310S Stainless Steel Bar is a high-temperature resistant austenitic stainless steel bar manufactured by Jiangsu Cunrui Metal Products Co., Ltd.. This grade contains high levels of chromium and nickel, giving it excellent oxidation resistance, strength retention, and superior corrosion resistance in aggressive environments.
Our 310S Stainless Steel Rod is produced strictly according to international standards such as ASTM A276, ASTM A479, and EN standards. Each bar is supplied with mill test certificates, chemical composition reports, and can be verified through third-party inspections if required. The material delivers stable mechanical properties, good toughness, and reliable performance even under continuous exposure to elevated temperatures.
Features & Advantages
High Temperature Resistance: Retains strength and oxidation resistance up to 1100–1200°C.
Superior Corrosion Resistance: Performs well in oxidizing and sulfidizing environments compared with standard stainless steels.
Excellent Weldability & Formability: Suitable for machining, welding, bending, and cutting without cracking.
International Certification: Compliance with ASTM, EN, JIS, and ISO standards ensures global acceptance.
Long Service Life: High durability reduces maintenance costs and downtime.
Applications of 310S SS Bar
The 310S SS Bar is widely used in industries that require resistance to high temperatures and corrosive atmospheres. Common applications include:
Furnace parts, heat treatment equipment, and boiler components.
Petrochemical and refinery processing units.
Kilns, burners, and combustion chambers.
Power generation plants and heat exchangers.
Food processing equipment requiring heat and corrosion resistance.
