Stainless steels are high-alloy steels which have high corrosion resistance when compared to other steels due to their high content of chromium. They are divided in to ferritic, austenitic, and martensitic steels based on their crystalline structure. Precipitation-hardened steels are another group of stainless steels. They are a combination of martensitic and austenitic steels.
