Unifit Metal Alloys is a known exporter and seller of SS 347 / 347H Pipes and Tubes, which is extremely resistant to sensitization (grain boundary carbide precipitation).

Stainless Steel UNS S34700 High Pressure Pipes has the following features: increased creep resistance Excellent shape-ability, High temperature tensile and rupture strength, corrosion and pitting resistance, and so forth. In the as-welded state, it exhibits high resistance to intergranular corrosion. It has great ductility when annealed and can be easily roll-formed, deep pulled, and bent. The fundamental advantage of this Stainless Steel WNR 1.4550 Cold Rolled Coiled Tubes is that it can withstand greater temperatures for longer periods of time without sensitization (precipitation). It possesses higher creep resistance, excellent formability, rupture and tensile strength at high temperatures, corrosion and pitting resistance, and other properties.

SS 347H 90 Square Pipe, SS 347 Bush Hex Pipe, DIN 1.4550 Welded Pipes, 347 Stainless Steel Electropolish Pipe, Stainless Steel 347H ERW Pipes, UNS S34700 Seamless Pipes, SS 347H Butt Weld Fittings, ANSI B16.9 Stainless Steel 347 Heat Ex-changer Tubes Manufacturer In Mumbai, India.

347 Stainless Steel Bright Annealed Pipes is used in the chemical and pharmaceutical industries, surgical and medical instruments, surgical implants, digesters, evaporators, and handling equipment in the paper industry, petroleum refining equipment, textile industry equipment, textile tubing, and so on. It should be air-cooled after forging and annealed after forging for the optimum corrosion resistance. Such Stainless Steel UNS S34709 Heat Exchanger Tubes are of excellent quality, and before selling them to customers, we rigorously evaluate the full array on well-defined quality parameters in order to provide a fault-free range. At cryogenic temperatures, it exhibits exceptional strength and hardness. Because of its low cost and simplicity of manufacture, it is widely utilized in the oil & gas and chemical sectors.

Stainless Steel WNR 1.4961 Polish Pipes is also utilized in cookware, cutlery, hardware, medical tools, big appliances, industrial equipment, and skyscrapers and massive structures as a construction material. This steel must be annealed to restore ductility and decrease hardness for further forming processes. 347H Stainless Steel Hexagonal Tubes is also often used in food processing equipment, brewery equipment, chemical and petrochemical equipment, laboratory benches and equipment, coastal architectural panelling, coastal balustrading, and other similar applications. We can sell our products in every part of the country thanks to our extensive distribution network and efficient transportation.
