Product Description
Product Description
This precision CNC turned alloy steel 42CrMo spline shaft features carburizing heat treatment to HRC 55-62 for maximum surface hardness and wear resistance. The 42CrMo (AISI 4140 equivalent) material provides excellent core strength and fatigue resistance. The spline is machined to DIN 5480 standard with ±0.01mm profile accuracy. Each shaft undergoes case depth measurement, hardness traverse testing, and magnetic particle inspection before shipment. Suitable for automotive transmissions and heavy machinery drivetrains.
As a leading CNC turning manufacturer with over 15 years of precision machining experience, we produce Precision CNC Turning Alloy Steel...

Frequently Asked Questions
Q: What is 42CrMo steel equivalent to?
A: 42CrMo is the Chinese standard equivalent to AISI/SAE 4140, DIN 42CrMo4, and JIS SCM440. It offers excellent hardenability, strength, and fatigue resistance.
Q: What spline standards can you machine?
A: We machine DIN 5480, ANSI B92.1 (involute), JIS D2001, SAE straight-sided, and custom spline profiles. Spline gages are used for 100% inspection.
Q: What is the carburizing process?
A: Our gas carburizing process diffuses carbon into the surface at 900-950°C, followed by quenching and tempering. This produces a hard, wear-resistant case (HRC 55-62) with a tough, ductile core.
