ASTM A335 P9 Alloy Steel Seamless Pipe

Stockist of ASTM A335 Gr P9 Welded Pipe in Mumbai

ASTM A335 Grade P9 Pipe is a high pressure high temperature pipe type used in the oil and gas, heat exchangers, boiler and power generation type of applications. These pipes are also known as the UNS S50400 Pipes under the UNS classification. There are welded and seamless pipes that are produced through ERW, EFW, welded and seamless technologies. The ASTM A335 Gr P9 Welded Pipe is of a ferritic alloy and does not require preheating before welding.

P9 Alloy Steel Pipe

P9 Alloy Steel Pipe

The pipes can be welded with most conventional welding methods. The P9 alloy steel pipe does not require post weld heat treatment because of the material composition. There is 0.9% molybdenum, 8% chromium and carbon, manganese, phosphorus, sulfur and silicon in the SA335 P9 Pipe material composition. The minimum tensile strength of the material is 415MPa and the minimum yield strength of the material is 205MPa.

ASME SA335 P9 Pipe

The ASTM A335 P9 ERW Pipe has only 0.15% carbon so that it makes welding easy and affordable with less prone to intergranular corrosion. The localized corrosion effects are also very less in the Alloy Steel P9 Smls Pipes and therefore these can be used in heavy welding applications. These are pressure pipes as indicated by the letter P in the naming of the grade. The SA335 Gr P9 Chrome Pipe is also highly corrosion resistant, especially against pitting.
