6 Steps In The Manufacturing Process Of a Stainless Steel Product

Stainless steel is a metal that is widely used in modern construction. This alloy is widely used in the construction of decorative elements due to its corrosion resistance and pleasing appearance, particularly in areas with unfavorable atmospheric influences. Stainless steel is literally all around us and you can also use custom PVD coating.

Yet how many of us are familiar with the way this type of metal and its derivative products are made? There are six major steps in the production of stainless steel, according to this article:

Here Are 6 Steps In The Production of Stainless Steel

  1. Melting And Casting

The raw materials that make up a stainless steel item are combined and melted in a massive electric furnace. During this step, intense heat is applied repeatedly for 8 to 12 hours. When the melting process is finished, the molten steel is cast into the desired semi-finished forms. Slabs, blooms (rectangular shapes), billets (round or square), rods, and tube rounds are some of the most common forms or shapes.

  1. Forming

The semi-finished steel shapes go through a series of forming operations in the second stage. For example, stainless steel is hot rolled (heated and passed through enormous rolls) and PVD coating michigan. The aforementioned blooms and billets are converted to bar and wire. In contrast, slabs are formed into plates, strips, or sheets. As the most versatile stainless steel form, semi-finished steel shapes are frequently turned into bars (it comes in all grades and sizes). There are round, squared, octagonal, and hexagonal bars, each suitable for a specific application.

  1. Heat Treatment

During this step, the various stainless steel forms are thoroughly annealed. Annealing is another term for heat treatment that involves heating and cooling stainless steel in a controlled environment. The goal of this heat treatment is to release pent-up stress within the stainless steel and soften the material, making it more suitable for a wide range of applications. The people in charge of carrying out the annealing process must exercise extreme caution because even minor changes in temperature, pressure, duration, or cooling rate can result in a faulty product.

  1. Descaling

A certain amount of scale appears on the surface of the stainless steel during the annealing process. This scale can be removed through a variety of processes known collectively as descaling. Pickling is one of the more common ways to perform the descaling process.

  1. Cutting

In this step, the semi-finished, heat-treated, and descaled stainless steel forms are cut into specific shapes. Mechanical cutting is done using guillotine knives, blanking, nibbling, and high-speed blades.

  1. Finishing

Finishing is used to give the stainless steel product its distinctive aesthetically pleasing appearance. Finishing is also required to make the stainless steel product smooth and easy to clean, which is a must in sanitary applications.

Stainless Steel Fabrication And (re)passivation

Steel is delivered to construction companies and PVD coating companies craftspeople in a variety of forms, including bars, plates, and sheets. However, its installation and application in the manufacture of various products (for example, stainless steel tanks) generally necessitate additional fabrication and processing. When we think of stainless steel fabrication, we usually think of processes like cutting and welding.

Unfortunately, both treatments destroy the protective layer on the surface of the steel, significantly reducing its corrosion resistance.


In addition to steel’s traditional properties, stainless steel has corrosion and heat resistance. It has all of the benefits of steel plus a few of its own. It is less prone to corrosion, can withstand harsh environments better, and has a longer service life. It is not, however, completely stain-proof. To begin, corrosion resistance is grade dependent. However, abnormal environmental conditions such as low oxygen, poor circulation, and high salinity can permanently stain it.

Different Types of Pvd Coating

PVD which is an acronym for physical vapor deposition can be determined as a process that includes the vaporization of a metal material which is then condensed to the surface of the production part in form of a coating. The quality of these production parts increases significantly as the physical vapor deposition or the PVD coating process enhances the durability, and toughness of the product and makes it oxidation and chemically resistant.  There are a lot of industries namely, automotive, medical industry, and aerospace which use this process time and time again. This helps to improve the overall performance of the product and brings a lot of comfort in terms of ease of cleaning. Let us further look at the three popular types of PVD coating

Three Main Types of PVD Coating

This incredible technique of physical vapor deposition first came into prominence during the early period of 1970s. They picked up a great pace in terms of usage in the late 90s and were essentially being used by every major industry. There are several processes of the PVD which are covering a large spectrum of work with super incredible attributes. Vapor deposition, sputter deposition, and thermal evaporation though are three of the popular and commonly used forms. Each of the processes in the PVD coating has got its subsets but they all are providing incredible results.

  • Thermal Evaporation

Thermal evaporation is divided into two main categories, one is electron beam deposition and the other is pulsed laser deposition. Both of these processes take the help of energy in evaporating any material such as chromium, aluminum, copper, or titanium in the vacuum. Now the vapor through the vacuum enters the production parts which are comparatively cooler where they get a chance to condense to take the formation of the hardened metal state. The process of thermal evaporation is mostly used in micro fabrication, packaging, and the computer industry.

  • Sputter Deposition

Magnetron sputtering and ion beam sputtering are the two different type of deposition that is being used in manufacturing applications these days. The process of the ion beam is used to navigate a high electric field towards the material’s surface to vaporize. This led to the ionization of metal vapor gases directing the moment of ions towards the part of the production. Magnetron sputtering though is slightly different where the charged ions get the required acceleration by the electrical field which is then superimposed to targeted directions. The medical industry highly prefers to use this process.

  • Arc Vapor Deposition

The most popular PVD plating process which is highly preferred by Surftech Inc is arc vapor deposition. The process involves the usage of a low-volt arc to vaporize the surface of the metal. Now the evaporated atoms of the metal start to combine with molecules of the gas and again the process of condensation starts in cooler production parts situated nearby. a multi-axis carousel help to spin the parts in production and distribute them in equal quantity for perfect coating. This process has come into prominence because it is one of the most environmentally friendly processes.

Surftech INC has years of experience in dealing with PVD coating as well PVD plating process. Our team will be all thrilled to help you understand the various processes and suggest what will suit best for you.
