p91 seamless steel pipe

P91 steel is equivalent to the national standard T91/P91 (10Cr9Mo1VNb).

p91 Specifications:
The outer diameter of the hot-rolled tube is 32-630mm. Wall thickness 2.5 ~ 75mm.
Cold-rolled (cold-drawn) tube outer diameter 5 ~ 200mm. Wall thickness 2.5 ~ 12mm.

P91 seamless steel pipe has high high temperature strength, excellent oxidation resistance and good process performance.

P91 seamless steel pipe not only has high oxidation resistance and high temperature steam corrosion resistance, but also has good impact toughness, high and stable durable plasticity and thermal strength.

P91 steel chemical composition:

Grade	P91
chemical composition	C	Mn	Si	P	S	Cr	Mo	V	Nb	N	Al
Wt(%)	≤0.40	0.12	0.6	0.5	9.5	1.05	0.25	0.1	0.07	—	—

P91 seamless steel pipes are mainly used as pipes or structural parts for conveying fluids, and have become ideal steel for power plant boilers.
