说明
Alloy Steel A335 P11 Distributor， ASME SA335 Alloy Steel P11 Pipe， Stockist of UNS K11597 Alloy Steel Pipe. ASTM A335 Grade P11 is also commonly known as ASME SA335 Grade P11 Pipes， it is a seamless ferritic alloy-steel pipe that mainly has high-temperature applications. The UNS designation for this grade P11 is K11597.
The key elements of P11 pipes are carbon， manganese， phosphorous， sulfur， silicon， chromium and molybdenum. Its key components are chrome and moly that provide it with strength， resistance against wear， hardenability as well as corrosion resistance properties. It is also possible to heat treat this alloy. The chromium within the alloy increases its resistance to oxidation allowing it to be used in corrosive high-temperature environments. Molybdenum addition enhances strength and wear resistance.P11 pipe material has high toughness and high wear and tear resistance.

Heat Treatment， Inspection & Test
Pipes of ASTM A335 P11 may be either cold drawn or hot rolled. Each pipe shall be reheated for heat treatment – full or isothermal annealing， normalizing and tempering at a temperature no less than 1200°F(650°C).
Hydrostatic test shall be performed on each pipe length of ASTM A335 P11 along with dimensional inspection and visual examination. Longitudinal or transverse tension test， flattening test， or bend test shall be performed for each heat number of furnace. When specified by the purchaser， one of the alternative nondestructive tests can be performed: ultrasonic test， eddy current test， or flux leakage examination. Hardness test is not necessary.
