What is Stainless Steel?

Stainless steel is an alloy steel of Fe with over 11% of chromium. It has corrosion resistance by passive coat on the surface of the steel and lasts beautiful conditions longer.
Corrosion resistance of stainless steel is improved as chromium content rate becomes higher and passive coat becomes better.

Classification of Stainless steel

Classification of Stainless  steel Martensitic Ferritic Austenitic Duplex Precipitation Hardening

Applications

To keep the properties such as corrosion resistance, mechanical property, workability and heat resistance, stainless steel is applied to a variety of field, e.g. tableware, kitchen tool, construction material, parts for machinery, medical appliances, chemical equipment and aircraft.

Notes

Stainless steel does not always have advanced corrosion resistance under corrosive condition at all times. And depend on heat treatment, cold working and surface condition, the properties of stainless steel would be greatly different even same grade.

Machining/working on stainless steel may have great difficulties comparing to ordinary grade of steel. Each grade of stainless steel has suitable machining/working and heat treatment by application.

You need to carefully consider suitable properties of stainless steel according to the condition of application.
