Stainless Steel Grade 403
Stainless steels are high-alloy steels with good corrosion resistance due to the presence of large amounts of chromium in these steels. Most of the stainless steels contain about 10% of chromium.
Stainless steels are available in three different groups based on their crystalline structure. These groups include martensitic, austenitic and ferritic. The combination of martensitic and ferritic steels forms a fourth group of stainless steels known as precipitation-hardened steels.
