Omfang

This specification covers the chemical and mechanical requirements for stainless steel hexagon socket button and flat countersunk head cap screws intended for use in applications requiring general corrosion resistance. The following three conditions are covered: austenitic alloy group 1 AF in an annealed condition, austenitic alloy group 1 CW in a cold-worked condition, and austenitic alloy group 1 CW1 in a cold worked condition. Screws shall be formed by upsetting or extruding, or both and shall be roll threaded and annealed to obtain maximum corrosion resistance and minimum permeability. The chemical composition, which shall be determined by chemical analysis, shall conform to the requirements for carbon, manganese, phosphorus, sulfur, silicon, chromium, nickel, copper, and molybdenum. The screws shall be subjected to tension tests and shall conform to the breaking strength, tensile strength, extension, yield strength, elongation, and Vickers and Rockwell hardness requirements. Corrosion test shall also be conducted to determine the susceptibility of the specimens to intergranular corrosion.
