Low-Distortion Steel for Precision Tooling
Kunshan Guanghouhong was recognized as a National High-Tech Enterprise in 2021. In 2025, we received the Jiangsu Provincial Private Science and Technology Enterprise designation. 9Mn2V Cold Hardening Steel is one of the grades we regularly process.
This material contains 0.85% to 0.95% carbon, 1.7% to 2.0% manganese, and 0.1% to 0.25% vanadium. It offers very low heat treatment distortion. It also provides good machinability and reliable toughness.
During processing, we use a spectrometer to check chemical composition. We use hardness testers to confirm hardness for every batch. This ensures that our products maintain stable and reliable performance.
Ideal for Precision Knives and Slender Punches
9Mn2V Cold Hardening Steel is suitable for precision knives used in plastic processing, slender punches, printing rollers, and measuring tools. If you need an economical choice for precision cold stamping dies under light loads, this material performs well.
For heat treatment, we recommend oil quenching at 780°C to 820°C. The tempering temperature is 160°C to 190°C. Hardness after quenching reaches 58 to 62HRC.
We support custom orders based on technical drawings. We can adjust size and hardness according to your requirements. Our production line includes precision surface grinders and CNC gantry mills. We handle precise dimensional processing.
Complete Pre-Sales and After-Sales Service
Before purchase, our technical team discusses your requirements. We provide material selection advice and cost estimates based on your application.
During production, we update you on order progress. After delivery, we provide usage guidance. If any issues arise, we respond quickly. We generally arrange technical support within 24 hours.
We conduct regular customer follow-ups to collect feedback. If material quality problems occur, we provide replacement or compensation according to the agreement.
