At Piyush Steel, we are a trusted 321 stainless steel round bar manufacturer and supplier, renowned for their strength, resistance to corrosion, and capacity to tolerate elevated temperatures. These bars are widely used in many industries, such as chemical processing, power plants, aerospace, and maritime applications. Stainless steel 321 bars are ideal for applications that are exposed to temperatures as high as 900°C because of their remarkable resistance to oxidation and capacity to operate in harsh environments.
Table Of Content
Although titanium (Ti) is present in the austenitic stainless steel alloy used to make 321 stainless steel bars, carbide precipitation is avoided during welding and exposure to high temperatures. 17–19% chromium (Cr), 9–12% nickel (Ni), 0.08% carbon (C), 2% manganese (Mn), and trace elements including sulfur (S) and phosphorus (P) make up its chemical makeup. These bars are extremely resistant to intergranular corrosion, oxidation, and scaling because they are composed of a well-balanced mixture of metals. This advantage implies that they can be utilized in exhaust systems, boiler tubes, furnace components, and heat exchangers.
We manufacture 321 round stainless steel bars in a range of sizes, with lengths up to 6 meters and diameters between 5 and 500 mm. To accommodate a range of industrial requirements, these bars are available in round, square, flat, and hexagonal forms. Customers can select from a variety of finishes, including polished, brilliant, cold-drawn, and hot-rolled finishes, depending on the application. We especially appreciate our 321 stainless steel hex bars in structural applications where strength and accuracy are crucial.
Our 321 round bars made of stainless steel meet the standards set by ASTM A276, ASTM A479, ASME SA276, ASME SA479, and DIN 1.4541. This means they have better mechanical properties, won't rust, and will last longer. These standards guarantee that our bars meet the strictest industrial requirements, making them suitable for critical applications across multiple industries.
After years of experience, Piyush Steel is dedicated to providing premium stainless steel 321 bars that satisfy global requirements. We put our bars through a thorough testing process that includes hardness testing, tensile strength analysis, PMI testing, and ultrasonic inspection to ensure great dependability. Stainless steel 321 round bars, hex bars, and other stainless steel items are best purchased from us since we provide affordable pricing, personalized solutions, and international delivery.
