ASTM A335 P12 Alloy Steel Seamless Pipe

ASTM A335 Gr P12 Welded Pipe Stockist in Mumbai

ASTM A335 P12 pipe is a ferritic alloy pipe made as seamless through cold drawing production methods. The SA335 P12 material has carbon, manganese, phosphorus, sulfur, silicon, chromium and molybdenum in the composition. Because of the material composition of the ASTM A335 Gr P12 welded pipe, it has 415MPa minimum tensile strength, 205MPa minimum yield strength and 30% minimum elongation rate. The Alloy steel P12 pipes can be heat treated for strength. It could be normalized, annealed, isothermal annealed or quenched and tempered.

P12 Alloy Steel Pipe

The SA335 Gr P12 ERW pipe is made by electric resistance welding and is easy to weld with. The carbon content and alloying elements contents are less so that the intergranular corrosion is less and it avoids localized corrosion on welded locations. The ASTM A335 P12 Grade Pipes don’t need to be preheated for welding or post weld heat treated for stability. The pipe size ranges from 1/8 inches to 42 inches.

ASME SA335 P12 Pipe

There are different schedules correlating to the wall thickness. The UNS K11562 Chrome Pipe schedules can range from 20 to XXH and heavier wall thicknesses as well. The specification can also be ASTM A213 for high pressure services. The P12 Alloy Steel Seamless Pipe is mostly used in the oil and gas and in heaters, boilers and in heat exchanger applications.
