Our steel shaft forgings 4140 shaft forgings have high fatigue strength, wear resistance, impact resistance, toughness, and torsional strength. Our 4140 shaft forgings have high strength, high hardenability, good toughness, 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 properties.
Our steel shaft forgings 4140 shaft forgings tensile strength can be more than 1080MPa and a yield strength more than 930MPa. The steel shaft forgings 4140 shaft forgings used for manufacturing forged steel shafts is 100% compliant with ASTM A29/A29M and SAE A29.
Usually, the steel shaft forgings 4140 shaft forgings we provide can be delivered as rough turning + quenching and tempering. According to customer requirements, we can also add a rough turning or semi fine turning after heat treatment. Our steel shaft forgings 4140 shaft forgings have retained a reasonable machining allowance. Greatly reducing the buyer’s subsequent processing time and cost, improving production efficiency, and shortening production time.
As experts in custom manufacturing of shaft forgings, we have rich knowledge and experience, and can customize steel shaft forgings according to your drawings and requirements.
