WR50A weather steel in the standard of BS4360 is a weather resistant steel created by alloying copper, chromium and nickel.
WR50A weather steel has added phosphorous which makes the material best suited for gas flue applications and for aesthetic facias .
WR50A weather steel Dimension scope (mm): T 6-650*W 1200-4020*L 5000-18000
Trading term : FOB,CIF,CNF
WR50A weather steel is a steel of steel for resistant to atmospherical corrosion steel,WR 50 A has good resistance to atmospheric corrosion, alloying elements played a decisive role,
first, to reduce the conductive properties of the rust layer itself precipitate and cover the steel surface;
second impact of the rust layer phase structure and typeshinder the growth of the rust layer;
the third postpone rust crystals;: Accelerated steel evenly dissolved; fifth; acceleration F + conversion to Fe, and can hinder the rapid growth of the corrosion products;: alloying elements compounds blocking cracks and defects. Different weathering steel alloying elements of its resistance to atmospheric corrosion.
