What is Stainless Steel? How is it made?

Below is an overview of how stainless steel is manufactured, from mines to manufacturers. But how does stainless steel move from a pile of scrap and refined minerals to its final form and application? Most stainless steels production begin in a similar manner before the process begins. This process determines the exact composition of the steel alloy, as well as its many properties. Therefore, to understand how stainless steel is manufactured, we must first dive into its composition. Step 1: Melt The production of stainless steel begins with melting scrap and additives in an electric arc furnace (EAF). EAF uses high power electrodes to heat the metal for hours to produce a fluent molten mixture. Step 2: Remove carbon content   Carbon helps increase the hardness and strength of iron. However, too much carbon can cause problems such as carbide precipitation during welding. Calibration and reduction of carbon content to appropriate levels are essential before melting molten stainless s...

  Stainless steel (an iron alloy containing at least 10 percent chromium) is most commonly used to make steel fittings for hydraulic systems. Stainless steel has the strength and reliability of pure steel and high chemical and corrosion resistance. Thanks to these qualities, this material is well suited for use in hydraulics, particularly in conditions where the liquid or the environment is corrosive. The increased resistance to corrosion increases the life of the hose assemblies. The strength of stainless steel at low temperatures is much higher than that of carbon steel. Industrial stainless steel fittings are often rated at 10,000 psi. Inch and specially designed stainless steel fittings can handle pressures up to 20,000 psi. Inch. Reliable, durable, corrosion-resistant stainless steel fittings generally cost more than fittings made from other materials. Durable fittings for aggressive environments When Corrosion Resistance is Vital Stainless Steel is the Perfect Fit. The hydrau...

How is stainless steel made?

Until the 1950s and 1960s, when the development of AOD (argon oxygen decarburization) and VOD (vacuum oxygen decarburization) was seen, the process of manufacturing stainless steel was time-consuming and costly. However, these two developments have revolutionized the production of stainless steel, significantly reducing raw material costs, increasing productivity and improving quality. This has led to the remarkable growth of steel production from the 1970s to the present. How is stainless steel made? The properties of the final alloy can be refined by varying the number of various elements. Importance of chromium in the manufacture of stainless steel There is no viable alternative. Chromium is a tough, corrosion-resistant transition element that gives stainless steel corrosion resistance. In general, the higher the chromium content, the more resistant the steel to corrosion. Removal of carbon content This is done by processing the molten metal with an AOD (Argon Oxygen Decarburization...
