How is stainless steel made?

Stainless steel can be cast or wrought. The main difference is in how it is formed into a final product. Cast stainless steel is made by pouring liquid metal into a molding container with a specific shape. Wrought stainless steel starts out at a steel mill, where continuous casters make stainless into ingots, blooms, billets, or slabs. These raw manufacturing materials must then be shaped by further work. They are reheated and reworked using rolling or hammering techniques.

What is stainless steel made of?

Like all steel, stainless steel starts out with a mixture of iron and carbon. What sets this family of alloys apart is that stainless also has a minimum of 10.5% chromium. This element gives stainless steel its characteristic resistance to oxidation. When stainless steel is exposed to the atmosphere, the chromium combines with oxygen to form a thin, stable passivation layer of chromium (III) oxide (Cr2O3). The passivation layer protects the interior steel from oxidization, and quickly reforms if the surface is scratched.
