A691 Gr 1/2 CR Alloy Welded Pipe is a chromium-molybdenum alloy steel that combines strength, toughness and excellent corrosion resistance.
A691 Gr 1/2 CR Alloy Steel Pipe is usually used in high temperature environments, such as pressure vessels, heat exchangers, piping systems, boilers, etc.
In order to improve the mechanical properties of A691 1/2CR Carbon Alloy Steel Pipe, in addition to carbon, the alloy steel also contains a large amount of elements such as nickel, tungsten, molybdenum, chromium, silicon, manganese, vanadium and a small amount of commonly used elements. The addition of these alloying elements can improve the strength, chemical resistance and hardness of the steel.
