Products Description
SMA570W weathering steel sheets as a low alloy anti-corrosion steel, the minimum yield of SMA570W weathering steel sheets is 420 Mpa and its tensile strength should be between 570 Mpa and 720 Mpa.
It belong to corrosion-resistant steel plates, also known as weathering steels. Weathering steels perform well in toughness, plasticity, forming, welding, abrasion resistance, high-temperature performance, and fatigue resistance.
They are widely used in various high-rise buildings, super-tall buildings, long-span structures, and lightweight steel/panel construction projects, especially in engineering projects with high fire-resistant and weathering requirements under harsh conditions.
SMA570W weathering steel sheets can be attached with other special technical condition requirements, such as flaw detection, Z-direction, simulated post-weld and other special technical conditions.
SMA570W weathering steel sheets corrosion resistant steel plate carbon equivalent is less than 47% when the thickness of steel plate is less than 50mm.
SMA570W weathering steel sheets is mainly used in steel structures exposed to the atmosphere for long periods, such as railways, vehicles, bridges, towers, photovoltaic systems, and highway projects.
