XM-19/S20910
Stainless Steel
XM-19 / S20910 is a high-nitrogen strengthened austenitic stainless steel. It combines exceptional high strength, excellent corrosion resistance and fully non-magnetic properties. Its yield strength is nearly twice that of conventional 316L stainless steel, providing outstanding resistance to pitting, crevice corrosion and chloride stress corrosion. It maintains excellent toughness and structural stability from cryogenic to elevated temperatures, and features good weldability and formability. Wi
Advantage
1.Extra high mechanical strength reinforced by nitrogen, much stronger than standard austenitic stainless steel 2.Superior pitting, crevice and stress corrosion resistance in chloride and seawater environments 3.Excellent low-temperature toughness and high-temperature structural stability for extreme working conditions 4.Fully non-magnetic performance with reliable weldability and comprehensive processing performance
