What is ASTM A335 P11?

 

 

P11 is a low-alloy heat-resistant steel, belonging to alloy steel, of which the most prominent advantage is one hundred percent recyclable, according to the production process, P11 can be divided into two kinds of hot-rolled seamless steel pipe and cold-rolled seamless steel pipe, of which cold-rolled pipe is divided into two kinds of round pipe and profiled pipe.

The production process of hot rolled seamless steel pipe is round billet, heating, piercing, three-roll diagonal zigzag, continuous zigzag or extrusion, stripping, stemming, cooling, billet, straightening, hydrostatic test, marking, storage.

Cold rolled seamless steel pipe making process is round billet, heating, piercing, beating, annealing, pickling, oiling, multi-pass cold drawing, billet pipe, heat treatment, straightening, water pressure test, marking, storage,

Physical Properties of ASTM A335 P11

ASTM A335 P11 is an alloy steel that combines high strength with high ductility.The physical properties of P11 grade alloy steel are that it has a yield strength of 300 MPa and maintains its properties at elevated temperatures. The grade's high-temperature strength makes it particularly suitable for temperature-sensitive applications, such as automotive, power generation, nuclear and gas turbines. Because of its good weldability and formability, this alloy steel is often used as a base material for many construction projects. It is also used to make a variety of parts from turbine blades to fasteners because of its ability to withstand shock loads in these applications. Because of its combination of strength, flexibility and heat resistance, P11 grade alloy steel is an excellent choice for many industries.

Heat treatment

 

Tubes of ASTM A335 P11 may be cold drawn or hot rolled. Each tube should be re-tempered - fully or isothermally annealed, normalised and tempered at a temperature of not less than 650°C.

Along with dimensional and visual inspection, each length of ASTM A335 P11 pipe should be hydrostatically tested. Longitudinal or transverse tension tests, flattening tests or bending tests shall be carried out on each hot number of the furnace. When specified by the buyer, one of the alternative non-destructive tests may be carried out: ultrasonic testing, eddy current testing or solder leakage testing. Hardness testing is not necessary.
