Work Item
ASTM WK83002

Revision of A1018/A1018M-18 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


Structural Steel Grades 50 and 55 are currently published per ASTM A1011 for thicknesses less than 0.230". These grades are currently produced and available in the marketplace for thicknesses 0.230" and greater. Since ASTM A1018 does not include Structural Steel grades greater than SS 45, these grades are currently being supplied based on agreement between producer and user and there is no ASTM definition for the parameter associated with these grades, such as mechanical properties, chemistry, testing, etc. This ballot item will establish consistency and uniformity of requirements in the marketplace by providing definition in ASTM A1018 for heavy thickness structural steel grades SS 50 and SS 55.
