ASTM A335 P11 Alloy Steel Seamless Pipe

Supplier of ASME SA335 P11 Material in India

ASTM A335 P11 Pipe Suppliers produce the pipes known as 1.25Cr-0.5Mo pipes due to the composition of the pipes. These are pressure pipes made up of different production technologies. The ASTM A335 Gr P11 ERW Pipe is made through the electric resistance welding. There is manganese, phosphorus, sulfur, silicon, chromium and molybdenum with 0.05 carbon in the SA335 p11 material. Since the carbon content is very low, the material is easy to weld upon. The pipes can be heat treated for strength.

P11 Alloy Steel Pipe

The ASTM A335 P11 alloy steel pipe can either be fully annealed or isothermal annealed, normalized and tempered over 650 degrees Celsius temperatures. The minimum tensile strength of the ASTM A335 Grade P11 smls pipe is 415MPa and the minimum yield strength is 205MPa. The pipes get furnished with plain ends or with buttweld in most cases.


The applications of the UNS K11597 Alloy steel P11 welded pipe can be seen in the marine, sea water, brackish water, water purification industrial applications because of the corrosion resistance of the Alloy Steel a335 p11 pipe against chloride ion stress corrosion cracking. The applications also include pressure applications such as oil and gas, boiler, condenser and power generation plant components. The Low Alloy steel P11 seamless pipe comes in various dimensions according to the different standards.

We offer ASTM A335 Grade P11 smls pipe in square/ rectangle/ round shape.
