UNS S17400 is a martensitic, chromium-nickel-copper precipitation-hardening stainless steel. UNS S17400 Stainless Steel Plate is capable of attaining a wide range of strength and toughness properties depending on the precipitation or aging temperature used in hardening. Its valuable combination of high strength, good corrosion resistance and toughness in both base metals and welds gives designers opportunities to add reliability to their products while simplifying fabrication and often reducing costs. High strength is maintained to approximately 600F (316C). UNS S17400 SS Plate has good resistance to stress corrosion cracking in the lower strength conditions.
