The most common grades of martensitic stainless steel include:

• 410: General-purpose grade with good corrosion and oxidation resistance. Commonly used in fasteners and cutlery.

• 420: Higher carbon content than 410, providing better hardness. Often used in surgical tools and knife blades.

• 440C: High carbon and chromium content, offering superior hardness and wear resistance. Suitable for high-end bearings and valve parts.

    Each grade can be heat-treated to improve mechanical performance.

As a factory supplier, we offer these grades in bar, sheet, and custom-forged formats.

We also support special packaging and third-party inspections for export clients in the Middle East and Southeast Asia.
