Our axle shaft forgings 4140 forged steel tensile strength can reach more than 1080MPa and the yield strength can reach more than 930MPa. The 4140 steel forgings material that is used in the making of the axle shaft forgings 100% comply with ASTM A29/A29M and SAE A29. 4140 forged steel is chromium-, molybdenum-, and manganese-containing low alloy steel. Our 4140 forged steel has high fatigue strength, abrasion and impact resistance, toughness, and torsional strength, high strength, high hardenability, small deformation during quenching, and high creep strength and endurance strength at high temperatures. Fully meet the requirements of high strength, wear resistance, and good mechanical performance of the axle shafts.
We supply the axle shaft forgings 4140 forged steel at suitable length and the correct diameter. These axle shaft forgings can be delivered by rough turning + Q & T ( oxide surface) or rough turning Q & T ( bright surface). Our forgings reserve a reasonable machining allowance for the subsequent processing. Greatly reducing the time and cost of the next processing step.
All of our steel forgings have undergone strict inspections, including chemical composition testing, dimensional testing, ultrasonic non-destructive testing, mechanical performance testing, and more. Confirm that the chemical composition and mechanical properties of the forgings fully meet the standards.
As the custom axle shaft forgings manufacturing expert, we have rich knowledge and experience to create custom axle shaft forgings according to your drawings and requirement.
