440C Stainless Steel Bar

440C Stainless Steel Bar

440C stainless steel is a high-carbon martensitic stainless steel known for its exceptional hardness, wear resistance, and ability to achieve a high polish. It offers the highest hardness among stainless steels after heat treatment, making it ideal for applications requiring high strength and edge retention, such as knives, bearings, and cutting tools. However, its corrosion resistance is lower than that of austenitic grades, but it performs well in mildly corrosive environments.

Type of Stainless Steel:

Stainless steel is divided into austenitic stainless steel, ferritic stainless steel, martensitic stainless steel, and duplex stainless steel according to the structure state.

Austenitic Stainless Steel

stainless steel with an austenitic structure at room temperature. Steel contains Cr≈18%, Ni≈8%-25% and C≈0.1%. Steel has high toughness and plasticity, but low strength.

Martensitic Stainless Steel

A steel whose mechanical properties can be adjusted by heat treatment. It has different strength and toughness at different tempering temperatures.

Duplex Stainless Steel

Austenitic and ferrite each account for about half of the structure. When the C content is low, the Cr content is 18% to 28%, and the Ni content is 3% to 10%. Some steels also contain alloying elements such as Mo, Cu, Si, Nb, Ti, and N. This type of steel has the characteristics of austenitic and ferritic stainless steel

 

Ferritic Stainless Steel

It contains 15% to 30% chromium and has a body-centered cubic crystal structure. This type of steel generally does not contain nickel, and sometimes contains a small amount of Mo, Ti, Nb and other elements. This type of steel has the characteristics of large thermal conductivity, small expansion coefficient, good oxidation resistance, and excellent stress corrosion resistance.

Austenitic Stainless Steel 201, 301, 304, 305, 310, 314, 316, 321, 347, 370, etc
Martensitic Stainless Steel 410, 414, 416, 416, 420, 431, 440A, 440B, 440C, etc
