Preston Pipes & Alloys is a trusted supplier of premium stainless steel bars to a variety of industries. Our stainless steel 310 / 310S round bar is known for its high-temperature resistance. These are austenitic stainless steel bars made from a combination of carbon, manganese, silicon, phosphorous, sulfur, chromium, molybdenum, nickel, and iron. SS 310 is stronger, whereas SS 310S is more weldable and has a lower carbon content, which reduces carbide precipitation. These bars are manufactured in accordance with EN, DIN, JIS, ASTM, BS, ASME, and AISI specifications. As a leading Stainless Steel 310S bar suppliers, we ensure reliable material quality and precise dimensions.


ASTM A276 Type 310 Bar provide excellent strength and heat resistance. With a density of 7.9 g/cm³ and a melting point around 1402°C, it works well in extreme heat. It has a tensile strength of 75000 psi (515 MPa) and a yield strength of 30000 psi (205 MPa), making it strong and stable. These bars can handle working temperatures above 1150°C, making them suitable for high-heat industrial setups. Stainless Steel 310S round bar offers solid mechanical properties and is made using processes like hot rolling, cold drawing, annealing, and peeling to maintain finish and strength.


SS 310 / 310S Round Bar

SS UNS S31000 Round Bar comes in diameters from 4mm to 500mm. Available lengths from 1 to 6 meters or as per custom needs. Surface finishes include black, bright polished, rough turned, matte, BA, and No.4 finishes. We offer them in round, square, hex, rectangular, billet, ingot, and forged forms. UNS S31008 Rod is used in heat treatment trays, furnaces, power plants, and chemical plants. The SS 310 round bar price in India varies based on size, finish, and order quantity.


Our stainless steel 310 rod goes through tests like PMI, IGC, hardness, tensile, flaring, flattening, and ultrasonic checks. We pack each order securely with end capping, plastic wrapping, and wooden boxes to avoid damage. Products follow ASTM A276, A479 / ASME SA276, SA479 standards and are available in custom surface finish, end finish, dimensions, shapes, sizes, length, and toughness.
