Good weather resistance of ASTMA588 weathering steel

ASTMA588 weathering steel: Its characteristics are high strength, good weather resistance, excellent cold deformation processing performance and welding performance.

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

In the marine atmospheric environment, it can resist harsh corrosive environments such as seawater, salt spray, microorganisms, and humid air, and has a certain ability to resist fatigue and seawater corrosion.

Weather-resistant steel plates are divided into low-alloy weather-resistant steel and medium-alloy steel plates according to their thickness. The difference between the two lies in the carbon content. Low-alloy weathering steel can be used for a long time in the atmospheric corrosion environment, usually the thickness does not exceed 0.10 mm (including 0.10 mm), and the carbon content does not exceed 0.10%. Generally refers to the thickness of 0.5 ~ 2.0m.

Medium alloy weathering steel is similar to low alloy weathering steel, but worse than low alloy weathering steel.

The weather-resistant steel plate also has good low-temperature toughness and weldability, and can be used in the range of -50°C to +150°C, and has good plasticity and weldability in the range of -30°C to +80°C.
