ASTM A572 Grade 50 vs C60
Side-by-side chemical composition and mechanical property comparison.
Overview
ASTM A572 Grade 50
The most widely used structural steel grade in the United States. 345 MPa (50 ksi) yield strength HSLA steel. Has largely replaced A36 for structural applications due to higher strength-to-weight ratio. Used for building frames, bridges, heavy equipment, and general structural fabrication.
C60
1.0601
High-carbon unalloyed quenching and tempering steel. High hardness and strength after heat treatment but difficult to weld. Used for springs, hand tools (screwdrivers, pliers), agricultural blades, wear parts, and railway components.
