What Are the Common Grades of Martensitic Stainless Steel and Their Properties?

[2025-07-28 10:11:16]

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 ... Read More

How Can Martensitic Stainless Steel Be Heat-Treated for Maximum Performance?

[2025-07-28 10:12:01]

Heat treatment is essential for unlocking the full potential of martensitic stainless steel. The process usually involves three stages: Austenitizing: Heating the steel to 950–1050°C to form austenite. Quenching: Rapid cooling in air or oil to form hard martensite. Tempering: Reheating to 150–500°C ... Read More

What Are the Corrosion Resistance Characteristics of Martensitic Stainless Steel?

[2025-07-28 10:12:45]

Martensitic stainless steel offers moderate corrosion resistance compared to austenitic grades. Its resistance depends on chromium content and surface treatment. While grades like 410 and 420 are adequate for indoor or mildly corrosive environments, they may require coatings or polishing for use in ... Read More

What Quality Standards Should I Look for When Sourcing Martensitic Stainless Steel?

How Does Martensitic Stainless Steel Compare to Other Stainless Steel Types?

[2025-07-28 10:10:27]

Martensitic stainless steels differ significantly from austenitic and ferritic grades. Austenitic steels, such as 304 and 316, are non-magnetic and offer superior corrosion resistance, but they cannot be hardened by heat treatment. Ferritic steels offer good corrosion resistance and magnetic ... Read More
