Product Description

不锈钢 拷贝


We supply 310S stainless steel bars, a high-alloy austenitic stainless steel designed for prolonged service in elevated temperature and oxidizing environments. With high chromium and nickel content, this grade offers exceptional resistance to oxidation, carburization, and thermal fatigue, making it suitable for extreme heat applications.

Core Features

  • Superior High-Temperature Resistance: Suitable for continuous service up to 1150°C (2100°F) with excellent scaling resistance.

  • Oxidation and Carburization Resistance: Performs well in oxidizing, sulfidizing, and carburizing atmospheres.

  • Good Corrosion Resistance: Maintains durability in acidic, alkaline, and chloride-containing environments at moderate temperatures.

  • Excellent Weldability and Formability: Can be welded and formed using standard austenitic stainless steel techniques.

Applications
Ideal for furnace components, heat treatment fixtures, radiant tubes, boiler parts, kiln hardware, and high-temperature fasteners.

We provide bars in rounds, squares, hexagons, and flats, with options for cutting, heat treatment, machining, and surface finishing. Full material certification compliant with ASTM A276, EN 10088-3, JIS G4303, and related standards is included to ensure quality and traceability.
