1018 HR Special Bar Quality
HOT ROLLED & COLD FINISHED
PACIFIC 1018 is the standard analysis for low carbon machinery steels and is best known for use in "cold rolled" bars. PACIFIC's hot rolled 1018 offers consistent machinability with good weldability. This special quality 1018 meets ASTM A576 special bar requirements and is vacuum degassed, calcium treated and ultrasonic tested for soundness. These bars are rough turned oversize to finish at nominal size for economical machining. This grade can be surface hardened by carburizing but does not respond to through hardening heat treatment.
