Welding performance of ASTMA588 weathering steel

1. ASTMA588 weathering steel is a special steel with high atmospheric corrosion resistance. It has good low-temperature impact performance in the temperature range of -50°C-+150°C, and has good low-temperature impact performance in the temperature range of -40°C-+150°C. Has good high temperature impact properties.

2. ASTMA588 weathering steel is an excellent cold work hardening steel, which has high strength when used in atmospheric corrosion and marine atmospheric environment.

3. It has good plasticity and welding properties in the temperature range of -50°C-+150°C.

4. ASTMA588 weathering steel is a special kind of steel with high carbon content and more alloying elements. The silicon content can reach 0.75%-0.75% (the grade is 12 MnSiVNb); adding trace amounts of manganese (0.02%) and chromium (0.01%) can improve the hardenability of steel; in addition, adding a small amount of elements such as niobium, vanadium and titanium can improve the atmospheric corrosion resistance.

5. ASTMA588 weathering steel has good welding performance and cold bending processing performance.

6. ASTMA588 weathering steel has good mechanical properties, good strength and plastic bonding performance in the temperature range of -50°C-+150°C, and good cold bending processing performance.
