P91 T91Alloy seamless steel tube high pressure boiler tube petroleum cracking tube
Product Description
P91 steel is equivalent to national standard 10Cr9Mo1VNb. T91 / P91 (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 allowable stress 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.
