Production Process of A105 Carbon Steel Forged Bars
Forging aligns the grain with the bar, enhancing strength under pressure.
Heat Selection & MTC Check
Killed carbon steel heats screened against A105 chemistry limits
Controlled Heating
Billets soaked evenly to forging temperature – no cold cores
Open-Die Forging / Rolling
Section reduced progressively for uniform grain flow along the axis
Heat Treatment
Normalizing (A105N) or annealing where the order or class demands it
Finishing
Bright drawing, peeling, polishing or descaled black as ordered
Testing & Marking
Tension, hardness & PMI checked; bars stamped with grade, heat & size
