10Cr9Mo1VNbN seamless steel pipe Equivalent: 

A213 T91    A335 P91

10Cr9Mo1VNbN seamless steel pipe features: 

10Cr9Mo1VNbN pipe not only has high oxidation resistance and high temperature steam corrosion performance, but also has good impact toughness and high stability and lasting plasticity and thermal strength. When the temperature below 620 ℃,  stress of 10Cr9Mo1VNbN pipe is higher than the austenitic stainless steel.
