Martensitic Stainless Steel Product Overview

Martensitic Stainless Steel Product Overview

Product Description:

Martensitic stainless steel is a type of alloy that combines high strength and hardness with good corrosion resistance. It is widely used in applications where both mechanical properties and corrosion resistance are critical. SD-steel, a leading supplier of high-quality stainless steel products, offers an extensive range of Martensitic Stainless Steel tailored to meet the diverse needs of our global clientele.

Product Overview

Martensitic stainless steels are characterized by their high tensile strength and hardness, making them ideal for applications requiring exceptional wear resistance and toughness. These steels are magnetic and can be heat-treated to achieve specific mechanical properties. They are commonly used in applications such as cutlery, surgical instruments, and automotive components due to their excellent combination of strength and corrosion resistance.

Material Properties

Martensitic stainless steels are primarily composed of iron and chromium, with additional alloying elements like carbon, nickel, and molybdenum. The addition of these elements enhances their mechanical properties and corrosion resistance. The most common grades include 410, 420, and 440 series, each offering unique benefits depending on the specific requirements of the end-use application.

| Grade | Composition (approximate wt%) | Typical Applications |

|------------|------------------------------------|---------------------------|

| 410 | Fe-12%Cr, up to 0.15%C | Cutlery, shafts, gears, and bearings |

| 420 | Fe-13%Cr, up to 0.15%C | Surgical instruments, valves, and pumps |

| 440C | Fe-17%Cr, up to 1.2%C | High-strength parts, bearings, and tools |
