Aung Metals has earned a strong reputation as a trusted leader in the metal industry, specializing in high-quality stainless steel products designed to meet diverse industrial requirements. Our SS 310S Hollow Bars are crafted with exceptional precision and undergo rigorous quality control to ensure compliance with international standards and optimal performance. Produced using an advanced high-temperature rolling process, our SS 310S Hollow Bars are available in both hot-rolled and cold-drawn variants, fully conforming to the ASTM A276 Type 310S specification for superior durability and reliability.
SS 310S Hollow Bars are composed primarily of 25% chromium and 20% nickel, offering excellent resistance to oxidation and high-temperature corrosion. The alloy also contains small amounts of carbon, manganese, silicon, and sulfur. Mechanically, SS 310S provides high tensile strength (around 515 MPa) and yield strength (approximately 205 MPa), with elongation values of up to 40%. Its hardness typically ranges from 200 to 250 HB. These properties make SS 310S Hollow Bars ideal for high-temperature applications, including furnace parts, heat exchangers, and reactors.

The high chromium (25%) and nickel (20%) content in SS 310S enhances its resistance to corrosion by forming a protective oxide layer on the surface. This layer shields the material from aggressive environmental factors, preventing oxidation and corrosion in harsh conditions.
SS 310S Hollow Bars are commonly used in industries such as power generation, chemical processing, petrochemical, aerospace, and manufacturing. They are essential for components in high-temperature environments, including furnace parts, heat exchangers, boilers, reactors, and gas turbines.
SS 310S Hollow Bars are widely used in hot and humid environments due to their excellent oxidation and heat resistance. Typical applications include furnace parts, heat exchangers, boilers and chemicals. In addition to being used in power plants, petroleum refineries, and high-temperature components such as reactor cores and combustion engines, SS 310S Hollow Bars are ideal for gas turbines, exhaust systems, and industrial applications of other properties resistant to scaling, corrosion and heat cycling is important
