WIXSTEEL INDUSTRIAL OFFER THE BEST QUALITY Gear Steel Bar.
Gear steel bar is a general name for alloy steel which is suitable for gear process use steel, normally 20#, 20Cr, 20CrMnTi, 35#, 45#, 40Cr, 42CrMo, 35CrMo all can be used for gear process. All these steel need good performance on yield and tensile strength, hardness and toughness, surface with good abrasion but inner need good toughness, anti-impact property(shock-resistance). Gear steel is the key material for Auto, railway, vessel, and other engineer machine filed. Good gear steel should have best performance on hardenability when process in quenching, good hardenability can ensure the gear steel crystal grain well-distributed, after quenching, austenite crystal become well-distributed martensite, can obviously enhance the gear steel anti-fatigue performance, reduce the deflection after heat treatment.
