ASTM A312 TP347 Stainless Steel Pipe

ASME SA312 347 ERW Pipe and Stainless Steel 347 Seamless Pipe manufacturer in India

ASTM A312 Gr Tp347 is an austenitic stainless steel stabilized with columbium. The addition of columbium makes it perform under high oxidation condition under high temperatures at around 800 degrees Celsius. The A312 Tp347 is stronger and durable. There are different sizes of the pipes in the SA 312 Tp 347 grade that range from 1/2inches to 24 inches. They could be manufactured in seamless, electric resistant weld or in electrical fusion weld conditions. The electric fusion welded pipes could range from 6 inches to 100 inches. Oshwin Overseas is a leading manufacturer of 347 Stainless Steel Pipe products. We produce all kinds of pipes in this material grade in different dimensions.

Our SS 347 Seamless Pipe is used under high temperatures because it has good creep strength at higher temperatures. The mechanical properties along with the chemical composition of the material make it applicable along a wide range of applications. The use of the 347 SS Pipe is seen mostly in marine environment, boats, marine architecture, equipment and laboratory furniture and in aerospace industries as well. The SS 347 Erw Pipe is electric resistant welded and therefore it is good for heavily welded applications. Our SS 347 Welded Pipe products are stronger and can come in different shapes. The Stainless Steel 347 Round Pipe is the most common in this material grade but we also manufacture square and rectangular pipes as well. We can also take custom orders to produce specific products. Please contact us for further details.

Cost difference between 347 and 347h stainless steel?

The 347 stainless steel is austenitic chromium nickel stainless steel that is stabilized with columbium and tantalum. The major difference between the 347 and the 347H is the carbon content. So there is not much difference in the cost of the material. If there is cost difference, it is due to the lower use cases of the 347h that the manufacturers don’t have to produce much of the material in the same volume as the 347 material.

Both are corrosion resistant, heat resistant and have high tensile strength and yield strength. Both materials can be used in chemical processing plants, boilers, super heater elements and in other high temperature services. In these applications, there are some instances where the hardness and toughness of the material needs to be higher.

The 347h is used exactly for that. The manufacturing cost per unit decreases with the volume of production. The transportation, storage and other service costs also go down with the volume of production. The 347 is produced in high quantities than the 347h because the 347 is the most used. It is due to these reasons, the 347h cost might be slightly more than that of 347.
