ASTM A312 TP309 Welded Pipe and SS 309 ERW Pipes Supplier in India


One of the best properties of grade 309 is its endurance to elevated temperatures or heat. Similar to grade 310, the high inclusion of chromium to the alloy of Stainless Steel 309 Seamless Pipe gives it this endurance to heat. Under non-cyclic conditions, grade 309 is an austenitic alloy that can resist oxidation up to a temperature of 1900°F. However, this same property of the 309 Stainless steel Efw Pipes witnesses a slight reduction to a temperature of 1850°F, due to frequent thermal cycling.

Its endurance to high temperature is the reason why this material makes it the top choice for application involving furnaces, incinerators, catalytic recovery systems rotary kilns as well as calciners. The industries that benefit from the use of AISI 309 Welded Pipe are industries pertaining to fuel such as petroleum and the coal industry. The heat in these industries is extremely high and the survival of conventional steel or carbon steel pipes are at risk. But if the SS Din 1.4301 Seamless Tubing were to be used as material for structural piping systems, the longevity of said systems is much better. Apart from resistance to oxidation and its endurance to heat, the astm a312 tp 309 welded pipe may be considered for applications where conditions such as nitriding, oxidizing, cementing, and thermal cycling are possible. However, most manufacturers caution buyers while using alloy grade 309 stainless steel pipe under such conditions, as it would perish if the maximum service temperature were to be used.
