A335 gr P11 Welded Pipe & Alloy Steel P11 Seamless Pipes stockist in India


Grade P11 is referred to as chrome-moly alloy steel. This alloy steel has properties at a much elevated level in comparison to carbon steels. Usually, the percentage of elements in alloy steels like ASTM A335 P11 Pipes tends to be much higher than conventional steels. Thus, raising their efficiency to the next level. The alloying contents in grade P11 include both chromium and molybdenum, where the percentage of chromium is about 1.25. And the percentage of molybdenum in the Alloy Steel P11 Seamless Pipes amounts to approx 0.5%.

Though in comparison to stainless steel, the percentage of elements in alloy steels and the mechanical properties are lower, when the comparison is in terms of pricing, the ASTM A335 Grade P11 Seamless Pipes offers the buyer a cost effective alternative. It is not only the mechanical properties that receive a boost with the addition of chromium and moly to the alloy but the corrosion resistance properties of an SA335 Gr P11 Seamless Pipes often surpass conventional steel alloys. In grade P11, the inclusion of both elements serves individual purposes. For instance, adding chromium to alloy SA 335 P11 welded pipes improves the tensile and mechanical strength at elevated temperatures. Chromium also increases the resistance of the alloy to oxidation, while also boosting the yield strength and hardness at ambient temperatures. Molybdenum, on the other hand, improves the materials’ wear resistance properties as well as the impact qualities and hardenability of the a335 p11 steel pipe.
