JIS G4051 S15C low carbon steel owns very low carbon element. We henan KUNFENG can offer forged round bars OD 80 mm - 1200 mm. is in a large need,so we henan KUNFENG stock large quantity of forged bars in the warehouse, and various size round bars included.

JIS G4051 S15C owns low carbon element, which decides S15C round bar has lower strength,but toughness,weldability,cold punching press properties are good. Because of the properties limited, can only be used to produce parts that bears small load and requires high toughness. After carburization or cyanide carburizing treatment, can be applied to manufacture some parts with lower strength and abrasive wear requirements.

s are usually produced under the followed procedures: EAF arc furnace + LF purify affinage + VDF + ingot steel(bottom gating /argon) + forged + annealing + black polishing (turnery) + Sep 1921-C/c,D/d,E/e UT test + smooth edges with sawing .
