Vinit Stainless is a renowned SS 314 tubing manufacturer and supplier in Chennai, India, recognized for providing high-temperature resistant stainless steel solutions. SS 314 is a high-temperature austenitic stainless steel containing high chromium and nickel, with excellent resistance to oxidation up to 1150°C. Vinit Stainless makes sure that its SS 314 tubing conforms to high quality standards and is manufactured through state–of-the-art technology. It is well suited for use in furnace, kiln, and high-heat process environments. With the goal of performance and durability, Vinit Stainless offers SS 314 tubing that accommodates the toughest thermal applications.
SS 314 tubing has 23–26% Chromium, 19–22% Nickel, and an up to 0.25% carbon content. This allows for outstanding oxidation resistance at high temperatures. It provides tensile strength of about 620 MPa and yield strength of about 310 MPa. SS 314 also has good creep strength and thermal shock resistance. Though less resistant to corrosion in aqueous conditions than other grades of austenitic stainless steel, its excellent performance at high temperature and oxidative stresses makes it highly suitable for thermal process and furnace-related operations.

SS 314 tubing finds application in high-temperature operations that demand high oxidation resistance and mechanical properties. It is widely used in furnace parts, kiln linings, radiant tubes, and heat treatment baskets. Applications like metallurgy, ceramics, glass making, and petrochemical processing depend on SS 314 for operations subjected to extreme heat. The tube resists scaling in oxidizing conditions and is capable of withstanding continuous service up to 1150°C. Its toughness in structure as well as resistance to thermal attack render it feasible for applications in reheating furnaces and combustion chambers, where normal grades of stainless steel would suffer at a quick pace.
