ASTMA588 weathering steel product features

ASTM A588 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% (grade 12 MnSiVNb); %) 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.

Aluminum content 0.45% - 0.72% (grade 12 MnSiVNb);

The content of manganese in steel is 0.30%-0.55%.

Product Features:

ASTM A588 weathering steel has good low-temperature impact toughness, which is 3 times higher than ASTMA585, and can meet the requirements of various working conditions; it has strong fatigue resistance and high fatigue limit, and can be used to make medium and heavy-duty automobiles, tractors, construction machinery, etc. with high requirements. Load vehicles and hull structures, etc. Products are widely used in marine ships, construction machinery, offshore oil platforms and other products with harsh environmental conditions, and are the first choice for manufacturing weathering steel.

ASTM A588 weather-resistant steel plate has good low-temperature toughness, and can maintain good mechanical properties at -40°C; it can maintain good welding performance at -60°C.
