Stainless Steel Grade 254 SMO™ (UNS S31254)
Stainless steels are high-alloy steels. These steels are available in four groups that include martensitic, austenitic, ferritic, and precipitation-hardened steels. These groups are formed based on the crystalline structure of stainless steel.
Stainless steels contain larger amounts of chromium in comparison with other steels and thus have good corrosion resistance. Most stainless steels contain about 10% of chromium.
