2507 Super Duplex Stainless Steel Plate S32750 Steel Plate Stock 25% Cr Duplex
2507 Super duplex stainless steel plate S32750 steel plate stock 25%Cr duplex PREN ≥40.0
2507 (UNS S32750) 25% chromium duplex stainless steel
General attributes:
2507 alloy is a super duplex stainless steel composed of 25% chromium, 4% molybdenum and 7% nickel. Its strength and corrosion resistance are strong, mainly used in chemical processing, petrochemical and subsea equipment. It has strong resistance to chloride corrosion, higher thermal conductivity and lower thermal expansion coefficient. The high chromium, molybdenum and nickel content makes it highly resistant to pitting, crevice and uniform corrosion.
Its impact strength is also very high. 2507 Super duplex stainless steel alloy is not suitable for use at temperatures higher than 570 ° F. For a long time in such an environment, its toughness will decrease.
Application area:
Oil and gas industry equipment
Offshore platforms, heat exchangers, underwater equipment, fire fighting equipment
Chemical processing industry, utensils and pipes
Desalination plants, high-pressure RO plants and subsea pipelines
Mechanical parts (high-strength, corrosion-resistant parts)
Energy industry FGD system, industrial scrubbing system, absorption tower
