65Mn Spring Steel Sheet for Blades, Washers & Wear Parts | China Supplier
Unlike alloy spring steels designed for large suspension components, 65Mn Spring Steel Sheet is widely chosen for thin spring plates, industrial blades, wear-resistant parts, and stamped components. Its relatively high carbon and manganese content allows it to achieve high hardness after quenching, making it a practical material where wear resistance and elasticity are equally important. For manufacturers looking for a balance between performance and cost, 65Mn remains one of the most commonly stocked spring steel grades in China.

Why Choose 65Mn Spring Steel Sheet?
-
High Hardness After Heat Treatment
With a carbon content of around 0.65%, 65Mn can achieve high hardness after quenching and tempering, making it suitable for wear-resistant components.
-
Excellent for Stamping and Cutting
Annealed sheets are widely used for laser cutting, blanking, punching, and forming before final heat treatment, helping improve production efficiency.
-
Cost-Effective Spring Steel
Compared with chromium-alloy spring steels, 65Mn offers reliable mechanical performance while maintaining competitive material costs.
-
Widely Available
65Mn is one of the most commonly stocked spring steel grades, making it easier to source in various thicknesses with shorter delivery times.
Typical Applications
- Industrial Blades
- Disc Springs
- Spring Washers
- Scraper Blades
- Saw Blades
- Agricultural Knives
- Wear Plates
- Stamped Spring Parts
