Stainless Steel 321/321H Round Bars

Stainless Steel 321/321h round bars are a type of steel bar known as austenitic steel. You can find this in various sizes, shapes, and grades. Stainless steel 321/321h round bar is an excellent raw material because it has a low carbon content. Steel typically has high concentrations of nickel and chromium. When mixed with nickel and chromium, they can be easily treated with heat. Stainless Steel 321H Round bars are great for harsh acidic conditions and high temperatures.

Shree Viratra Enterprises is a famous company that exports and supplies SS 321 / 321H Round Bar. These bars have a high carbon content (.04 – 10), which enhances their high-temperature creep properties. Our production team makes these bars following national and international standards. Our experts and workers use their skills and knowledge to create the best product for various industrial uses.
The 321 Stainless Steel Rod is stainless steel stabilized with titanium. It is known for its ability to resist general corrosion. 321H Stainless Steel Round Bar has excellent resistance to oxidation and corrosion. They also have good creep strength. The SS 321 Round bar cannot be hardened through heat treatment. Instead, it can only be set through cold working. It is easy to weld and process using standard shop fabrication methods. The SS ASTM A276 321 Flat bar is suitable for temperatures between 425 and 900 °C. It works exceptionally well in environments with water that can cause corrosion. Stainless Steel 321H Rectangular Bar is used in acidic solutions without chloride or fluoride at moderate temperatures. The 321 SS Round bar was explicitly made for use in high temperatures between 1800 – 1500°F (427 – 816°C). It is because other alloys like 304 can be damaged by intergranular attack at these temperatures. Pickles the brushed seam area in SS 321H Round Bar by dipping or spraying. Sometimes, pickling pastes or solutions are used. After pickling, it is essential to rinse with water thoroughly. The 321H Stainless Steel Round Bar is good at resisting corrosion in many corrosive substances. It also strongly resists deformation and breaking under high pressure and stress. 321 Stainless Steel Round Bar is commonly used for various applications such as condensers, heat exchangers, filters, pressure vessels, valves, and more.
