P11 alloy steel pipe and T11 alloy steel pipe difference
 
 
P11 alloy steel pipe is the biggest advantage of 100% recycling, in line with environmental protection, energy saving, resource conservation national strategy, national policy to encourage the expansion of high-pressure p11 alloy pipe applications.

T11 alloy steel pipe is low hardenability cold work die general steel and carbon content of 0.6% or more of high carbon steel. The advantages of the steel is good machinability, with high hardness and toughness, but the hardenability is low, quenching deformation. Because the steel contains less alloying elements, low tempering resistance, hardened layer of shallow, and thus lower carrying capacity. With high hardness and wear resistance, grain growth sensitivity is small.
