316 stainless steel wire has a higher nickel content and 2-2.50% molybdenum, giving the alloy better corrosion resistance. With its superior cold working properties, it can be used in severe cold forming operations and exhibits short time tensile and creep strength properties at elevated temperatures.

Cold heading is the process of forging metal at temperatures close to room temperature without any additional heat. The hardness, yield strength and tensile strength of the metal can be improved by cold working.
Cold heading wire is mainly used for various kinds of fasteners manufacturing, for example: precision screws, bolts and nuts etc. And also in manufacturing rivet, nail, stable, pins for construction and automotive.
