Stainless steels are high-alloy steels that possess good corrosion resistance in comparison with other steels
due to additional chromium content.
Based on their crystalline structure, stainless steels are generally divided into three groups, namely,
martensitic, austenitic and ferritic. A combination of martensitic and ferritic steels forms a fourth group
called the precipitation-hardened steels.
