Nextgen Steel & Alloys is a reputed manufacturer of SS 347 Round Bar. Our company is the provider of these high-quality round bars. We buy raw materials from the vendor, and our materials are well-known in the market. The material and grade offer the best finishing’s to these round bars. This alloy is a stainless steel alloy that contains carbon, chromium, and manganese. Alloy 347 is a stainless steel grade with good corrosion resistance and excellent resistance in stable oxidizing conditions. Our SS 347 round bar has excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range. This round rod made of SS 347 has good oxidation resistance and high temperature creep resistance. At low temperatures, this alloy has good toughness. SS 347H round bar contains high carbon. Our company produces SS 347H Round bars, which show enhanced creep resistance and shows higher strength at elevated temperatures. SS 347 can only be hardened by cold forming, not heat treated. Based on standard manufacturing processes, SS 347H is easy to weld and process.
We provide SS 347H Round bars that show good physical properties like density, thermal conductivity, electrical resistivity, and specific heat. These round bars also show tensile strength, yield strength, elongation, and hardness. Our round bars are used in water supply systems, power plants, fabrication, and food processing industries. It is also used in the chemical industry and petroleum refining. For example, in hydrocarbon service, our round bars show resistance to polythionic acid stress corrosion cracking. Our team always makes efforts to produce a high-quality product. Nextgen Steel & Alloys pack products using the high standard system. We deliver our products all over the world.
Radiant superheaters, heavy wall-welded equipment, oil and gas refinery piping, boiler tubes and casings, aircraft exhaust stacks and collector rings, cabin heaters, heat exchanger tubes are the broad ranges of industrial applications that have used SS 347H Round bars. Our bars offer great flexible performance and offer great outcomes. About the surface finishing’s we offer the bright, matte finish, cleanser coated, or electropolish quality finishing’s to our SS 347H Round bars.
