ASTM 268 Standard Specification for Seamless and Welded Ferritic and Martensitic Stainless Steel Tubing for General Service. Covers standard specification for a number of grades of nominal wal thickness, welded ferritic and martensitic stainless steel tubing for general corrosion-resisting and high-temperature service.
The steel shall conform to the required chemical coompositon for carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, aluminum, copper, nitrogen, titanium, and columbium. The number of tubes in a lot heat treated by the continuous process shall be determined from the size of the tubes. The steel shall conform to the following tensile properties: tensile strength, yield strength, and elongation.
The tubes shall have a hardness number that will not exceed the prescribed Brinell and Rockwell hardness values. Several mechanical tests shall be conducted, namely: tension test; flaring test (for seamless tubes); flange test (for welded tubes); hardness test; reverse flattening test; intergranular corrosion test; and hydrostatic or nondestructive electric test.
