General Product Description

ASTM A1018 is a standard specification for hot-rolled, heavy-thickness coils of carbon steel, commercial steel, drawing steel, structural steel, high-strength low-alloy steel and ultra-high strength steel. The specification covers steel coils in thicknesses of 0.230 in. to 1.000 in. A1018 High-Strength Low-Alloy Steel with Improved Formability (HSLAS-F) Grade 70 has a specified minimum yield strength of 70 ksi.
