A Detailed Guide of Stainless Steel and its Manufacturing Process

Steel is undoubtedly one of the most prominent metals that are in existence today. It comes with a wide range of applications fit for all of the available industries. 

Steel occurs in diverse forms like Carbon Steel, Alloy Steel, Stainless Steel and Tool Steel. All of them are unique, with their list of advantages and disadvantages, but here we will deal with a major variant of steel known as stainless steel.

Stainless steel is an iconic form of steel, known specifically for its enormous strength and unparalleled lustre. It is used in all of the major industries which includes construction, dentistry, heavy machinery, surgery and the automobile industry to name a few. With the discovery of stainless steel, the Indian Steel Industry has taken a revolutionary turn for the general good.

Raw Materials for Manufacturing Stainless Steel

Stainless steel is an alloy of iron, coupled with several other elements, which includes, chromium, nickel, manganese, nitrogen and carbon. The properties of the metal can also be altered by varying the amounts of the elements.

Why is Chromium Added to Stainless Steel?

Chromium is one of the distinctive metals used in the production of stainless steel. This is because Chromium is hard and resistant to corrosion, lending the same attributes to the ultimate metal. However, it is imperative to go with the Best Steel manufacturer India to rest assured about the quality of the steel.

How is Stainless Steel Manufactured?

Stainless steel involves many steps to take the final form in which you find it. In case you are wondering about the manufacturing process of steel, here we list you all the major steps involved in it:

  • Firstly, all of the raw materials are melted in an electric arc furnace. It takes 8-12 hours of intense heat.

  • Next, the carbon content is removed from the metal by subjecting the metal in an AOD (Argon Oxygen Decarburization).

  • Now, the steel is stripped of the unwanted elements that exist in it. This process is known as tuning.

  • The molten steel is then cast into forms. Billets, blooms, slabs, rods and tubes are some of the commonly existing forms in which the steel is cast.

  • Then, the steel is subjected to the hot rolling process. The temperature is always above the re-crystallization temperature of steel.

  • Now, the steel is again subjected to a process known as cold rolling where the temperature is below the re-crystallization temperature of steel.

  • Annealing – This is a process of heating and cooling steel under artificial conditions, helping it to soften down, thereby, recovering from the earlier stresses.

  • The process of annealing forms scales on the steel, which ought to be descaled later on by pickling. Here, the steel is either bathed in nitric-hydrofluoric acid or an electric current is passed along the surface of the steel, rendering it free from the scales.

After going through these rigorous steps, the steel is finally cut into the desired forms and subjected to a proper finishing.
