ASTM A335 P11 Alloy Steel Pipe (Chrome Moly Pipe)
The A335 alloy pipes are distinguished by their higher alloying elements in comparison to standard carbon steel pipes. The ASTM A335 P11 Pipe is crafted with key chemical constituents, featuring 1-1.50% chromium, 0.44-0.65% molybdenum, 0.50-1% sulfur, along with minor traces of carbon, manganese, phosphorus, and silicon.
The design of the ASTM A335 P11 Steel Chrome Pipe revolves around its ability to resist corrosion in a variety of corrosive environments. These pipes exhibit exceptional oxidation resistance and excel under extreme pressures and temperatures. As per the NBR 5603 standard, P11 Chrome Pipe can undergo cold rolling or cold drawing processes following the initial hot-rolling phase.
Furthermore, these pipes can be heat-treated or subjected to isothermal annealing at temperatures up to 1200 degrees Fahrenheit. The SA335 gr P11 Round Pipe is extensively employed in various industries, including chemical, oil and gas transportation systems, sugar, petrochemical, and more. We proudly stand as the leading A335 P11 Pipe suppliers in India, offering top-quality products to meet your needs.
