ASTM A312 TP321H Stainless Stee

Product Name：ASTM A321 TP321H Stainless Steel  Pipe

ASTM A335 P91 Seamless Ferritic

ASTM A335 P91 steel is an improved 9Cr-1Mo steel. When V, Nb and other alloy elements are added into the original 9Cr-1Mo martensitic steel, the allowable stress at 550-650 ℃ is significantly higher than that of 10CrMo910 and TP304 steel. Compared with 10CrMo910 steel, under the same temperature and pressure conditions, the pipe wall thickness can be reduced by 50%. The recommended use temperature of A335 P91 steel is below 650 ℃, A335 P91 steel has good high temperature resistance and resistance Corrosion and creep resistance,
