ASTM A335 P11 Alloy Steel Seamless Pipe
A335 P11 seamless alloy steel pipe is mainly used for seamless alloy steel pipes used in petrochemical boilers, superheaters and heat exchangers.
P11 steel pipe is a kind of low-alloy heat-resistant steel, which belongs to alloy steel. The most outstanding advantage is that it is 100% recyclable. According to the production process, P11 heat-resistant steel pipe can be divided into two types: hot-rolled seamless steel pipe and cold-rolled seamless steel pipe. , among which cold-rolled pipes are divided into two types: round pipes and special-shaped pipes.
A335 P11 chemical composition: C: 0.05~0.15 Si: 0.50~1.00 Mn: 0.30~0.60 P≤0.025 S≤0.025 Cr: 1.00~1.50 Mo: 0.44~0.65
A335 P11 high pressure boiler tube mechanical properties: tensile strength ≥ 415Map, yield strength ≥ 205Mpa, elongation after break ≥ 30%,
A335 P11 pipe fittings delivery status: fully annealed or isothermal annealed, normalized + tempered.
A335 P11 seamless pipe specifications and dimensions: 60.3-765*2-120, common specifications diameter 60.3, 73, 88.9, 114.3, 168.3, 219.1, 273.1, 323.9, 355.6, 406.4, 457.2, 508, 559, 610, 660, 711 , 762, and other sizes can also be customized according to customer requirements.
