For shaft applications that require higher hardness, wear resistance, and strength after heat treatment, martensitic stainless steel offers a practical material choice. Its mechanical properties can be adjusted through quenching and tempering, allowing customers to match hardness, toughness, and strength according to the final working conditions.

After heat treatment, martensitic stainless steel can provide better surface hardness and mechanical performance than many general stainless steel grades. This makes it useful for precision shafts, mechanical parts, wear-resistant components, valve parts, pump parts, tooling-related components, and other applications where strength and durability are important.

Compass Power Tech manufactures martensitic stainless steel precision ground shafts in grades including 410, 416, 420, 420J2, 431, and 440C. For projects that require a balance between machinability, hardness, corrosion resistance, and load-bearing performance, our team can help customers select a suitable grade and processing route.
