Duplex Stainless steel
S32760, also known as Super Duplex 2507, is a high-performance duplex stainless steel that combines excellent strength and corrosion resistance, particularly in chloride-rich environments. It offers superior resistance to pitting, crevice corrosion, and stress corrosion cracking compared to standard duplex and austenitic grades. S32760 has high chromium and molybdenum content, making it ideal for demanding applications in the oil and gas, chemical processing, and marine industries. Its good weldability and toughness further enhance its versatility in various high-stress applications.

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 |
| Duplex Stainless Steel | S31803, S32101, S32205, S32304, S32750, etc |
| Ferritic Stainless Steel | 429, 430, 433, 434, 435, 436, 439, etc |
