Stainless steels are high-alloy steels. They have high corrosion resistance when compared to other steels due to the presence of large amounts of chromium. Based on their crystalline structure, they are classified into ferritic, austenitic, and martensitic steels. Precipitation-hardened steels are another group of stainless steels. They are a combination of martensitic and austenitic steels.
