P91 steel pipe application and properties

2021-01-04 17:01:54

P91 steel pipe is equivalent to the national standard 10Cr9Mo1VNbN, not only has high oxidation resistance and high temperature steam corrosion resistance, P91 steel pipe also has good impact toughness and high and stable durable plasticity and thermal strength. When the service temperature is lower than 620℃, the allowable stress of P91 steel pipe is higher than that of austenitic stainless steel. Above 550℃, the recommended design allowable stress is about twice that of T9 and 2.25Cr-1Mo steel.

P91 steel pipe can be used as high temperature superheater and reheater steel pipe for subcritical and supercritical boiler wall temperature ≤625℃, and high temperature header and steam pipeline with wall temperature ≤600℃. P91 steel pipe can also be used as nuclear power heat exchanger and petroleum cracking Installation furnace tube.

If you have any needs of P91 steel pipe, please contact us freely. We can offer the P91 steel pipe with high quality and best price.
