What is Stainless Steel Passivation?

28 Aug 22

No Comments

Stainless steel passivation is a process that hardens and protects the underlying metal layer of a stainless steel surface from corrosion. The term “passivation” comes from the Latin word for “to pass through.” Stainless steel passivation can be achieved in three ways: by physical, chemical, or electrochemical methods.

What is Stainless Steel Passivation?

Stainless steel passivation is a process of creating a protective layer on the surface of the metal to prevent corrosion. It is achieved by using a combination of chemical and physical methods. The most common method is anodic oxidation, which uses an electric current to create a film of ferric oxide on the surface.

Physical passivation can be achieved by using a variety of coatings, including oil, waxes, and aqueous solutions. Chemical passivation is usually achieved by using an acidic solution to create a protective layer of oxides. Electrochemical passivation is achieved by applying an electric current to create a film of ferric oxide on the surface.

The Benefits of Stainless Steel Passivation

Stainless steel passivation is a process of creating a protective oxide film on the surface of the metal through an exposure to an inert gas, such as nitrogen. This film prevents the metal from reacting with oxygen and other elements in the air, which would cause corrosion. Stainless steel passivation can be applied to both iron and steel, and is an important step in maintaining the quality of these metals.

Stainless steel passivation has a number of benefits. First, it protects the metal from corrosion. This can prevent damage to equipment and reduce costs associated with repairs or replacement. Second, stainless steel passivation creates a barrier that limits the amount of oxygen that can reach the metal’s surface. This prevents oxidation and discoloration in the metal, which can create a less than desirable appearance. Finally, stainless steel passivation protects the metal against other environmental factors, such as dust and moisture. By limiting the amount of contact that the metal has with these elements, Stainless Steel Passivation can help extend the life of the metal material.

Benefits and Applications

Stainless steel passivation is a surface treatment process for improving the corrosion resistance of stainless steel. It is a two-step process: first, the metal is treated with an oxide film to create a passive layer; and second, the metal is then passivated with a non-oxide film. Stainless steel passivation offers several benefits, including improved corrosion resistance and longer lifespan.

Passivation can be used to improve the corrosion resistance of stainless steel in a variety of applications. Passivation can be used on objects that are in direct contact with water, like pipelines and tanks, or objects that are exposed to air, like air conditioning units.

The benefits of stainless steel passivation include improved corrosion resistance and longer lifespan. Stainless steel passivation can reduce the amount of maintenance required on stainless steel equipment, which can extend the life of the equipment. Additionally, stainless steel passivation can improve the appearance of stainless steel products by creating a matte finish.

How to Passivate Stainless Steel

Passivation is a process used to protect stainless steel from corrosion by oxide and other reactive oxides. It involves coating the metal with a thin film of a protective material. The most common type of passivation is called stainless steel passivation.

Passivation Processes

Passivation is the process of making a metal surface non-conductive. The most common type of passivation is called stainless steel passivation. Stainless steel is a type of metal that is used in many applications where durability and resistance to corrosion are important factors. When stainless steel is made, it is coated with a layer of chromium that makes it resistant to corrosion. However, over time, even stainless steel can become corroded.

One way to protect stainless steel from corrosion is by passing an electric current through the metal. This process known as passivation creates a thin film of metal on the surface of the stainless steel. The film offers protection against corrosion and makes the metal more resistant to other types of damage.

There are several different types of passivation processes that can be used with stainless steel. Some common processes include: electron beam evaporation, ion Beam Deposition, sputtering, and plasma treatment. Each process has its own benefits and drawbacks that must be taken into account when selecting the right method for passivating a particular piece of stainless steel.

Computer-aided design or CAD engineering design is the method of creating, modifying, analyzing, and optimizing a three-dimensional design of a machine with the help of computers. Cad Engineering Design is very advanced software engineering. It involves designing a machine to suit a particular purpose. Such a design is called a prototype.

Prototyping Companies are professional companies who first study the requirement of the client. They then design a prototype with computer software. The design is checked for size and dimension. Then the working of the prototype is testing through simulation for safety and efficacy. When the prototype passes all the simulations and tests, then it is finalized as a product prototype. Three dimensional prototyping with CAD is an error-free method of designing and creating a new machine.

Molding with thermoplastics

Plastic Injection Mold Design refers to the production of spare parts made of a raw material called thermoplastic. The a combination of plastic with a metal like steel or aluminum is infused into a heated drum, combined and mixed, and poured into a molded cavity and left to cool. When it cools it hardens and takes the shape of the mold.
The mold itself is created by qualified and experienced industrial designing engineers so there is no room for errors. The mold is precision made and is customized to the requirements of every client.

Benefits of product designing and prototypes

Product Design Toronto involves development of prototype for a part of industrial machinery or the machine itself. The designs ensure that the ultimate product does not require must use of fasteners. This in turn ensures that there is a higher level of safety during assembly and operation of the machines. The points where fasteners are attached are the most vulnerable sections of machinery and can cause problems like:

  • Leakages of toxic liquids passing through the machines,
  • Breakages can lead to industrial accidents that could even prove fatal.

The prototypes checks for safety of a machine during installation and operation through simulated events to prevent such accidents.

Selective laser sintering (SLS) and Stereo-lithography (SLA) are both the latest in prototyping technologies. In the SLS method particles of plastic are fused with metal using lasers by a process called sintering, thus forming a thermoplastic. In SLA a requisite shape of metal is lowered into a resin that coats the metal on all sides. SLS/SLA Prototypes are sturdy, strong, and durable. Prototypes of any shapes and sizes can be designed with these methods. Browse through for more information.

Apa sajakah bagian – bagian dies mesin industri yang harus Anda ketahui? Apakah Anda juga sedang mencari bengkel mesin industri di Bekasi? Sahl Engineering Indonesia menyediakan berbagai perkakas mesin terlengkap, salah satunya dies. Dies sendiri merupakan alat pendukung proses stamping. Bila didefinisikan, dies adalah cetakan yang digerakkan mesin press untuk menekan atau mengepress material penghasil barang tertentu. Cara kerja dies, yaitu memotong plat lembaran sesuai dengan bentuk yang dikehendaki. Material yang biasanya digunakan adalah special alloy stell.

Bagian Dies Mesin Industri yang Harus Anda Ketahui

Berikut ini Bagian dies mesin industri yang harus Anda ketahui untuk mempermudah proses pengoperasiannya:

Upper Plate

Upper plate merupakan bagian teratas dari dies yang memegang dan menyangga beberapa komponen, seperti punch, punch holder, backing plate, stripper dan guide bush. Upper plate berguna sebagai tempat mengatur atau setting dengan ram sebuah mesin press. Bagian ini dibuat dari baja lunak karena mempertimbagkan fungsinya yang bukan sebagai pembentuk atau pemotong. Umumnya, bahan yang dipakai ialah SS 41 (JIS) dengan kandungan karbon 0,2%.


Punch ialah pisau pemotong yang berada di bagian atas (pada jenis proses cutting) atau cetakan atas (pada jenis proses forming). Punch yang berukuran besar dibaut pada punch holder, sedangkan yang kecil cukup ditanam dengan suaian sesak pada punch holder supaya tidak goyang saat dies dijalankan.

Punch Holder

Punch holder berguna sebagai pemegang punch, baik pada proses cutting maupun forming. Pada proses cutting, punch yang berukuran kecil ditanam pada punch holder karena difungsikan sebagai pengikat atau penahan.


Stripper berfungsi sebagai penjepit atau penahan material plat supaya tidak bergerak saat punch menyentuhnya dan dies dalam keadaan berjalan. Biasanya stripper dipakai pada proses cutting, tapi ada pula yang menggunakannya untuk beberapa proses forming. Konstruksi stripper sendiri ialah plat dengan ketebalan tertentu yang di bagian atasnya dipasangi spring. Supaya pergerakan spring tersebut tidak melenceng, maka stripper harus diikat pada upper dies dengan stripper bolt.

Lower Plate

Lawan dari upper plate, lower plate adalah bagian terbawah dari sebuah dies, dimana semua komponen seperti guide pin, die, pad dan lainnya dipegang serta diikat. Lower plate berfungsi sebagai tempat setting dengan meja mesin press atau bolster. Karena dari segi fungsinya tidak membutuhkan banyak kekuatan, material baja lunak juga dipilih untuk membuat lower plate.

Backing Plate

Backing plate berfungsi untuk menahan tekanan punch yang bekerja memotong material. Sebab, aksi tersebut menimbulkan reaksi pada ujung punch yang lain. Tempatkan backing plate di antara upper plate dan punch holder supaya tidak melubangi bagian teratas dies. Backing plate ini tidak selalu ada di konstruksi dies, tapi tergantung pada prosesnya.


Die memiliki fungsi yang sama dengan punch, tapi letaknya di bawah. Karena fungsinya sebagai pemotong atau pembentuk, die harus dibuat dengan material yang kuat serta keras.


Pad (lifter atau ejector) bentuknya sama dengan stripper, tapi berfungsi sebagai pendorong atau pengangkat material. Jadi, pad berguna untuk memudahkan operator dalam mengambil material hasil proses. Mungkin bila tidak ada pad, material tersebut akan menempel pada die.

Guide Post

Guide post adalah bagian yang sangat penting pada dies, sebab fungsinya sebagai penepat antara upper dan lower dies. Dengan adanya guide post, posisi antara die dan punch bisa terjamin saat dies dijalankan. Pada konstruksi dies, minimal harus ada dua set guide post.


Shank merupakan bagian dies yang terpasang pada upper plate. Fungsi shank adalah untuk menempatkan dies di posisi center dari ram mesin press. Pada beberapa jenis mesin press, khususnya yang memiliki kapasitas kecil, shank berfungsi sebagai pengikat dan pengencang upper dies. Sementara pada dies berukuran besar, shank jarang dipakai karena proses pengikatan menggunakan sistem clamping.

Demikianlah bagian- bagian dies mesin industri yang harus Anda ketahui. Dan tujuan pembuatan dies pada alat stamping adalah untuk menghasilkan komponen secara massal, dengan bentuk dan ukuran yang sama dalam waktu relatif singkat. Jadi, dengan mengetahui bagian-bagiannya, diharapkan Anda bisa menggunakan dies dengan baik setelah memesannya dari Bengkel Bubut Jababeka? Sahl Engineering Indonesia.
