ASTM A709 50W steel sheet process and parameters

ASTM A709 50W steel sheet is the Standard Specification for structural steel used primarily in the manufacture of steel bridges. ASTM A709 50W steel sheet covers high strength, low allowable steel structure shapes, plates and bars. In most environments, the atmospheric corrosion resistance of this steel is much better than that of carbon steel with or without copper.

Common parameters of ASTM A709 50W steel sheet
The thickness of ASTM A709 50W steel sheet is usually 1.5 mm ~ 4 mm, plate thickness is 4 mm ~ 20 mm, thickness 20 mm ~ 60 mm, special plate upward to 80 mm, conventional width of 0.5 m, 1 m, 1.2 m, 1.5 mm, 2 m and so on.

Process of ASTM A709 50W steel sheet
Rust stabilization treatment: rust stabilization treatment is a chemical method (liquid rust) in which the surface of the steel plate coated with ASTM A709 50W steel sheet is slowly dissolved to produce stable rust and form a uniform layer of rust. The rust layer with this protective effect can be the initial inhibition of outflow of stainless steel.
