ASTM A276 AISI 347 Stainless Steel Bar Manufacturer, Supplier, Stockist & Exporter from India

Triroundbars.com is one of the largest exporter, manufacturer and supplier of Stainless Steel 347 Round Bars in India. With a high resistance to extended heat and corrosion, 347 Stainless Steel Bars are ideal for power generation, engine, welded fabrications, and other elevated heat applications. In addition to being known as UNS S34700 bars, 347 Stainless Steel bars provide excellent mechanical characteristics through their superior creep and stress rupture properties than other grades, such as Stainless Steel 304.

We are recognized as the foremost manufacturer, exporter and supplier of ASTM A276 347 Round Bar. As per the international quality standards, this ASTM A276 347 Round Bar is designed with utmost precision.

As a matter of fact, it can be categorically said that steel bars are a key component of any manufacturing industry, or for that matter any industry which relies on machinery. Applications in automotive, textile, fabrication, construction, cement, ship building, paper and pulp, defence, heavy earth moving equipment, or aerospace.

347 (UNS S34700) is a columbium stabilised austenitic stainless steel plate with good general corrosion resistance and slightly better resistance to strong oxidising conditions than 321 (UNS S32100). It has excellent resistance to intergranular corrosion at temperatures in the chromium carbide precipitation range of 800 – 1500°F (427 – 816°C). The alloy has good oxidation resistance and creep strength to 1500°F (816°C). It also possesses good low temperature toughness.

Alloy 347H (UNS S3409) stainless steel plate is the higher carbon (0.04 – 0.10) version of the alloy. It was developed for enhanced creep resistance and for higher strength at temperatures above 1000°Chromium carbide precipitation occurs at temperatures between 800°F and 1500°F (427°C and 816°C), and it possesses excellent resistance to intergranular corrosion.

Alloy 347 stainless steel plates cannot be hardened by heat treatment, only by cold working. It can be easily welded and processed by standard shop fabrication practices.347 grade stainless steel diffChromium carbide precipitation occurs at temperatures between 800°F and 1500°F (427°C and 816°C), and it possesses excellent resistance to intergranular corrosion materials. SS 347 Round bars come in various thickness and dimensions to suit the requirements of our clients.

As part of the American ASTM standard, 347 stainless steel is a brand of stainless steel. 347 stainless steel is equivalent to 0Cr18Ni11Nb stainless steel in China. Stainless steel is a type of high alloy steel that can resist corrosion in air or chemical environments. Stainless steel has a beautiful surface and is corrosion-resistant. 

Surface treatments such as plating are not necessary, as stainless steel has inherent surface properties. It is commonly known as stainless steel. The representative properties are 13 chromium steel, 18-8 chromium-nickel steel, and other high alloy steels. Tantalum and niobium are used in 347 mainly for welding high temperature parts.

Stainless steel alloy 347 (UNS S34700) is a columbium stabilised austenitic stainless steel plate with good corrosion resistance and slightly better resistance to strong oxidising conditions than alloy 321 (UNS S32100). It exhibits excellent corrosion resistance after exposure to temperatures in the chromium carbide precipitation range of 800 – 1500°F (427 – 816°C). This alloy has good oxidation resistance and creep strength to 1500°F (816°C). It is also tough at low temperatures.

Alloy 347H (UNS S3409) stainless steel plate is the higher carbon (0.04 – 0.10) version of the alloy. It was developed for enhanced creep resistance and for higher strength at temperatures above 1000°F (537°C). In most instances, the carbon content of the plate enables dual certification.

Plates made from alloy 347 stainless steel can only be hardened through cold working, not by heat treatment. They can be easily welded and processed by standard shop fabrication techniques.
