Stainless & Maraging Steels

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, such as SS 416, SS 403CB and SS 420, 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. Stainless Steels such as SS 410 and SS 403 are examples of the martensitic group and 405 is an example of the ferritic group. The combination of martensitic and ferritic steels forms a fourth group of stainless steels known as precipitation-hardened steels which include 15-5 PH and 17-4 PH.
Maraging steel is a very high strength iron base, molybdenum, cobalt and nickel alloy.
