CarTech 20Mo-6 HS stainless is a 6% Mo austenitic stainless alloy possessing a unique combination of corrosion resistance and ultra high tensile strength capability (up to 280 ksi [1930 MPa]) with good ductility.

CarTech 20Mo-6 HS stainless is the result of compositional and processing modifications made to 20Mo-6 stainless for enhanced work hardening response.

The HS grade achieves high strength through cold work, not by heat treatment. In the cold-worked condition, CarTech 20Mo-6 HS stainless retains excellent resistance to environmental cracking and chloride-induced pitting and crevice corrosion while remaining nonmagnetic.

Applications:
Because of its combination of mechanical, physical and corrosion resistance properties, CarTech 20Mo-6 HS stainless is suited for aggressive environmental conditions where high strength is required.

The alloy has been used for cold-drawn rod and wire applications including single strand wireline (slickline) and armoring wire for oil and gas wells, springs, yacht rigging and non-magnetic cables.

CarTech 20Mo-6 HS stainless is not intended to replace 20Mo-6 stainless, particularly for sheet, plate, pipe or tubing applications since CarTech 20Mo-6 stainless does not require post-weld annealing.
