2507 (UNS S32750) 25% chromium duplex stainless steel
General attributes:
S32750 Super Duplex stainless steel pipe has strong strength and corrosion resistance, and is mainly used in chemical processing, petrochemical and subsea equipment. It has strong resistance to chloride corrosion, higher thermal conductivity and lower coefficient of thermal expansion. Higher chromium, molybdenum and nitrogen content it has a high resistance to pitting, crevice corrosion and general corrosion.
Its impact strength is also very high. The 2507 alloy is not suitable for use at temperatures higher than 570 ° C. If it is exposed to such an environment for a long time, its toughness will decrease. Its mechanical properties is shown below

Duplex stainless steel has an α + γ dual-phase structure, so its performance characteristics are built of austenitic stainless steel and ferritic stainless steel. It is a type of stainless steel with high strength and best corrosion resistance. Generally, in the case of low C content, 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, Nb, Ti, and N.
Compared with ferrite, it has higher plasticity and toughness, no room temperature brittleness, significantly improved intergranular corrosion resistance and welding performance, while maintaining the 475 ° C brittleness and high thermal conductivity of ferritic stainless steel, and has superplasticity, etc. Features. Compared with austenitic stainless steel, the yield strength is significantly improved, and the resistance to intergranular corrosion, stress corrosion, corrosion fatigue and abrasion is significantly improved.
Application fields are:
oil and gas industry equipment; offshore platforms, heat exchangers, underwater equipment, fire fighting equipment; chemical processing industry, utensils and pipeline industry; desalination plants, submarine pipelines; mechanical components (high-strength, corrosion-resistant components), Energy industry FGD system, industrial scrubbing system, absorption tower, etc.
Delivery form:Sheet, strip, bar, pipe (welded and seamless pipe), wire, forging, light rod, flange, welding
