A material mainly used in plants, tankers, seawater pumps, etc. Next-generation stainless steel with high corrosion resistance, lightweight, and high strength.
Duplex stainless steel is a high-strength, high-corrosion-resistant stainless steel that has a dual-phase structure of austenite and ferrite by adding an appropriate amount of nickel (Ni) to high chromium (Cr). Additionally, by adding molybdenum (Mo) and nitrogen (N) along with chromium and nickel, it offers a wide range of corrosion resistance and price options from general-purpose stainless steel classes to super stainless steel classes. In addition to excellent pitting resistance, it also has superior stress corrosion cracking resistance compared to general-purpose austenitic steels. Materials other than S32304 are also available.

basic information
【Features】 ○ Duplex stainless steel is a high-strength, high-corrosion-resistant stainless steel that has a dual-phase structure of austenite and ferrite by adding an appropriate amount of nickel (Ni) to high chromium (Cr). ○ In addition to chromium and nickel, by adding molybdenum (Mo) and nitrogen (N), it offers a wide range of corrosion resistance and price options from general-purpose stainless steel classes to super stainless steel classes. ○ It has nearly twice the strength (0.2% yield strength comparison) of SUS304 and SUS316, allowing for thin and lightweight designs. ○ In addition to good pitting resistance, it excels in stress corrosion cracking resistance compared to general-purpose austenitic steels. ○ Coated arc, TIG, and MIG welding can be performed using common alloy welding materials. Depending on the steel type, FCAW and SAW are also possible. ● For more details, please download the catalog or contact us.
