P91 Alloy Steel Pipe is a kind of pipe which has high class strength and temperature resistance because of the chrome moly alloy metal material. P91 Alloy Steel Pipe l is made under the temperature of 1050°C,and then cooled to the temperature 200 °C in the open air. After that, P91 Alloy Steel Pipe need to be heated through heating to 760 °C. All these process make P91 Alloy Steel Pipe have creep strength and durability. Within P91 Alloy Steel Pipe’s chemical elements, the chrome makes it have temperature strength and oxidation resistance. The molybdenum increases the elasticity, resistance to wear, and high temperature creep strength of P91 Alloy Steel Pipe.
