BioDur® 316LS stainless steel is an electro-slag remelted (ESR) or vacuum arc remelted (VAR), low carbon, high nickel and molybdenum version of 316 stainless. The secondary premium melting step (ESR or VAR) imparts improved cleanliness with chemistry modifications designed to maximize the corrosion resistance of this alloy and provide a ferrite free microstructure. The alloy is nonmagnetic even after severe cold forming operations and meets the requirements of ASTM F138, ASTM F139 and ISO 5832-1.
