What is Stainless Steel 347H Pipes?

The Stainless Steel 347H Pipes are the high-carbon variant of austenitic stainless steel with larger strength and further improved resistance to corrosion and oxidation. With a chemical composition rich in chromium, nickel, further stabilized by columbium and tantalum, these stainless steel pipes are ideal for stress-induced environments. The 347H pipes showcase great performances without rupture or distortion up to 1500°F.

Its high creep and stress-rupture strength make them particularly suitable for applications where sensitization is a problem. These pipes have a density of 7.96 g/cm³ and may be more difficult to weld due to the higher carbon content. The mechanical properties of 347H Stainless Steel Tubes are even better, offering greater strength and corrosion resistance than those of other variants.

The round pipes made from 347H are manufactured under ASTM A312 standards and therefore cannot undergo any heat treatment. Annealing at 1950°F with water quenching, however, brings about significant improvement in their performance in acidic environments. Manufactured from extruded steel billets, the Stainless Steel 347H Seamless Pipes access applications requiring unparalleled reliability and strength in high-pressure and temperature conditions. Economically practical versions, the SS 347H welded pipes are normally used for low and moderate pressure uses, manufactured by welding sheets or strips

347H ERW pipes are made through the process of high-voltage electrical resistance welding longitudinally by creating seams without filler materials. Metcore Alloys, the leading manufacturer, supplier, exporter, and stockist, supply a wide variety of 347H Stainless Steel Pipes specifically made with seamless, welded and ERW constructions.

Cabin heaters, aircraft exhausts, oil and gas refining systems, heat exchanger tubes, boiler casings (of high temperature water, super heated steam, hot gases, and oils), alongside other appliances, make use of these pipes. SS 347H pipes showcase excellent hardness, 201 Brinell, at a melting temperature of up to 1450°C and are meant for harsh conditions.

The tensile strength of more than 515MPa with a yield strength of 205MPa makes the ASTM A312 TP 347H pipes we deal with very suitable for use in heavy-duty industries. We deal with pipes that are also resistant to such aforementioned problems relating to intergranular corrosion and sensitization arising in grades 304 and 304L. These pipes, ranging in size from ½" to 24" NB, are known for high and low-frequency resistance-essential for many industrial purposes.

As trusted stockists and exporters, we offer customized solutions such as rectangular, square, and polished pipes to all your project requirements. Our SS 347H pipes are provided with AISI, UNS S34709, and DIN 1.4961 specifications for superior performance in both high and low-temperature applications.
