Product Description

Chrome Moly Alloy Flanges A182 F22 WNRF 

Product introduction
Chrome moly alloy flanges offer improved levels of chromium and molybdenum. The added chromium helps increase the steel's hardenability and corrosion resistance, whereas the increased molybdenum helps bolster its toughness and corrosion resistance.
Features
Strong creep strength
Improved rigidity
Superior hardenability
Robust wear resistance
Good impact resistance
Easy to fabricate
Applications
Chrome moly alloy flanges connect pipes, valves, pumps and other equipment, forming a piping system. They are ideal for applications carrying corrosive or high-temperature fluids or gases. Industries that could benefit from chrome moly flanges include:
Oil and Gas
Refinery
Power Generation
Chemical Processing
