PRODUCT INTRODUCTION
The yield strength of dual phase steel plate is more than twice that of ordinary austenitic stainless steel. This feature enables designers to reduce the weight when designing products, making this alloy more cost-effective than 316317l. This alloy is particularly suitable for the temperature range of - 50 ° f / + 600 ° F.

This kind of steel has the characteristics of both austenitic and ferritic stainless steel. Compared with ferrite, it has higher plasticity and toughness, no room temperature brittleness, significantly improved intergranular corrosion resistance and welding performance. At the same time, it also maintains the 475 ℃ brittleness, high thermal conductivity and Superplasticity of ferritic stainless steel. Compared with austenitic stainless steel, it has high strength and significantly improved resistance to intergranular corrosion and chloride stress corrosion. Duplex stainless steel has excellent pitting corrosion resistance and is also a nickel saving stainless steel.
