WR 50 A

WR50A Weathering Resistant Steel

Grade: WR50A Steel Plate
Standard: BS
Thickness: 4-200mm
Width: 1500-3000mm
Length: 3000-12000mm

WR50A Introduction
WR50A is a structural weathering steel which is also referred to as atmospheric corrosion resistant steel. The main alloying elements are chromium nickel and copper with added phosphorous which gives it excellent self-protecting qualities. As the steel reacts with elements in the atmosphere, the material forms a layer of rust over time which in essence protects the steel from corrosion.
WR50A steel is the Equivalent grade to S355J0WP (1.8945) steel in EN 10025 - 5: 2004 standard and FE510C1K1 steel in UNI standard and also E36WA3 steel in NFA 35-502 standard.
Delivery conditions for WR50A steel there are Hot Rolled, Cold Rolled, Normalized, Quenched, Tempering, Thermal Mechanical Control Process (TMCP), Electroslag Remelting Technical, HIC test.

WR50A Chemical Composition
Main chemical composition in BS WR50A steel: Carbon: max 0.12, Manganese MAX 1.00, Silicon max 0.75, Sulphur max 0.03, Phosphorus from 0.06-0.15. More detailed information, please refer to the flowing table:
