CNC-machined Alloy Steel 30CrMnSiA is a chromium-manganese-silicon steel that reaches at least 1,080 MPa tensile strength after quenching and tempering, with good toughness, suited to high-strength structural parts.
Alloy Steel 30CrMnSiA (GB/T 3077) is a medium-carbon chromium-manganese-silicon steel (about 0.28–0.34% carbon, 0.9–1.2% silicon, 0.8–1.1% manganese, 0.8–1.1% chromium).
Alloy Steel 30CrMnSiA is a good option for high-strength shafts, fasteners, and structural parts.
