Anotation

This specification covers the chemical, mechanical, and metallurgical requirements for wrought, nitrogen strengthened manganese-chromium-molybdenum low-nickel stainless steel alloy bars and wires used for surgical implants. All bars and wires should be furnished as specified in either annealed or cold-worked condition and in cold-drawn, pickled, ground and polished, ground, or any other specified finish. The products should conform to the required chemical composition, microcleanliness, purity, surface finish, tensile properties, and hardness and should pass the intergranular corrosion susceptibility test. Both wires and bars must have a homogenous microstructure and with grain sizes within the specified range.
