ASTM A1018/A1018M-23

Standard Specification for Steel, Sheet and Strip, Heavy-Thickness Coils, Hot-Rolled, Carbon, Commercial, Drawing, Structural, High-Strength Low-Alloy, High-Strength Low-Alloy with Improved Formability, and Ultra-High Strength

This specification covers standards for hot-rolled, heavy-thickness steel sheet and strip coils. The materials shall come in the following designations: (a) Commercial Steel (or CS) of Types A and B, and Standard Steel Designation; (b) Drawing Steel (DS) of Types A and B, and Standard Steel Designation; (c) Structural Steel (SS) of Grades 30[205], 33[230], 36[250] in Types 1 and 2, and 40[275]; (d) High-Strength Low-Alloy Steel (HSLAS) of Grades 45[310], 50[340], 55[380], 60[410], 65[450], and 70[480] in Classes 1 and 2; (e) High-Strength Low-Alloy Steel with Improved Formability (HSLAS-F) of Grades 50[340], 60[410], 70[480], and 80[550]; and (f) Ultra-High Strength Steel (UHSS) of Grades 90[620] and 100[690], Types 1 and 2. The strip and sheet coils shall conform to specified limit in width and thickness. Carbon, manganese, phosphorus, silicon, aluminum, silicon, copper, nickel, chromium, molybdenum, columbium, titanium, nitrogen, and boron contents shall be followed as specified by each designations, classes, types, and grades. Tension tests shall be performed. Materials shall adhere to yield strength, tensile strength, and elongation requirements. Guidelines for workmanship, finish, and appearance are given.
