ASTM A 1000/A 1000M

This specification covers round, shaped and flat rolled plain carbon and alloy steel spring wires, uniform in quality and temper, intended for the manufacture of mechanical springs that can withstand moderate fatigue stresses over some relatively low number of cycles. This wire shall be either in the annealed and cold-drawn or oil-tempered conditions. The steel may be made by any commercially accepted steel making process in either ingot cast or strand cast form. The percentage of the following elements: carbon, manganese, phosphorus, sulfur, silicon, chromium, and vanadium, shall conform to the chemical composition requirements and be determined by heat analysis. Tensile and wrap tests shall conform to the mechanical requirements such as tensile strength. Metallurgical requirements including eddy current testing for etched surface, decarburization, and inclusion content are detailed.
