What are the application fields of 10Cr9Mo1VNb steel

10Cr9Mo1VNb steel is equivalent to T91 and P91, corresponding to American Standard SA387GR91CL2. 10Cr9Mo1VNb not only has high oxidation resistance and high temperature steam corrosion resistance, but also has good impact toughness, high and stable permanent plasticity and thermal strength. When the service temperature is lower than 620℃, the service stress is higher than that of austenitic stainless steel. Above 550℃, the recommended design stress is about twice that of T9 and 2.25Cr-1Mo steel.

Application of 10Cr9Mo1VNb steel:
10Cr9Mo1VNb can be used as steel pipe for high temperature superheater and reheater of subcritical and supercritical boilers with wall temperature ≤ 625℃, as well as high temperature header and steam pipe with wall temperature ≤ 600℃. It can also be used as nuclear electric heat exchanger and furnace pipe of petroleum cracking unit.
