Abstract
This specification covers the requirements for 18chromium-12.5nickel-2.5molybdenum stainless steel alloy shot, bar, or ingot used for the manufacture of cast and solution-annealed surgical implants. This material is known to be paramagnetic. The product casting and casting alloy shall conform to the prescribed chemical requirements, tensile strength, yield strength, elongation and minimum reduction of area.
