Under normal circumstances, stainless steel will not rust. However, if the stainless steel is not used or maintained properly, or the environment in which it is located is too harsh, stainless steel may be rusted. When we see the yellow or orange rust on the steel surface, we can quickly confirm that it is a sign of rust.

Mechanical properties vary according to the type of stainless steel. Martensitic stainless steel has high strength and hardness and is suitable for manufacturing parts that are both corrosion resistant and require high strength and high wear resistance, such as turbine shafts, stainless steel tools, and stainless steel bearings.

In various procurement scenarios, we often need to determine the authenticity of stainless steel, which may use chemical identification, grinding identification, visual identification, magnet identification, etc.

Stainless steel has grown into many different subcategories. According to the difference of its various metal contents, it can be divided into Austenitic stainless steel, Ferricic stainless steel, Martensitic stainless steel, Duplex stainless steel and Precipitation Hardening stainless steel.

After the surface of the metal is corroded, it will be in contact with food and medicine, which will pollute food and medicine. Therefore, in such mechanical design, metal materials in contact with food and medicine are accustomed to using stainless steel. In addition, in high temperature environments, food is in contact with stainless steel, so the content of lead and nickel in stainless steel is also considered.

Stainless steel is a general term for a class of alloy steels which usually contain 10% to 30% chromium. This kind of steel is not as rusty as ordinary steel because its surface can form an oxide film, which has rust-proof properties. Stainless steel is used as a raw material in a large number of parts of pharmaceutical machinery, therefore understanding stainless steel can better select the machinery required.
