20Mo-6® HS stainless is the result of compositional and processing modifications made to 20Mo-6 stainless for enhanced work hardening response. It is a 6% Mo austenitic alloy possessing a unique combination of corrosion resistance and ultra-high tensile strength capability (up to 280 ksi [1930 MPa]) with good ductility. The HS grade achieves high strength through cold work, not by heat treatment. In the cold-worked condition, 20Mo-6 HS stainless retains excellent resistance to environmental cracking and chloride-induced pitting and crevice corrosion while remaining nonmagnetic. Because of its combination of mechanical, physical, and corrosion resistance properties, 20Mo-6 HS stainless is suited for aggressive environmental conditions where high strength is required.
