Stainless Steel 410S Forgings
410S, S41008
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.
Grade 410S stainless steel is a non-heat treatable version of grade 410 stainless steel.
Stainless steels are high-alloy steels with good corrosion resistance due to large amounts of chromium present in them. Most of the stainless steels contain about 10% of chromium.
