A58Gr.K Weather Resistant Steel

A58Gr.K Weather Resistant Steel

A588 Grade K Weathering steel chemical composition ASTM A588 Grade K Corten steel, A588 Gr.K steel plate/Sheet. A588 Grade K low alloy A588 grade K steel plate, A588 grade K weathering steel When properly exposed to the atmosphere, A588 Grade K is suitable for many applications in the bare condition. A588 grade K steel plate specification:Thickness:6MM to 200 Width:1500mm to 4050mm, Length:3000mm to 15000mm. A588 grade K chemical composition: ASTM A588 Corrosion-Resistant Structural Steel A Carbon 0.19% max Manganese 0.80-1.25% Phosphorus 0.030% max Sulfur 0.030% max Silicon 0.03-0.65% Nickel 0.40% max Chromium 0.40-0.65% Copper 0.25-0.40% Vanadium 0.02-0.10% B Carbon 0.20% max Manganese 0.75-1.35% Phosphorus 0.030% max Sulfur 0.030% max Silicon 0.15-0.50% Nickel 0.50% max Chromium 0.40-0.70% Copper 0.20-0.40% Weathering Steel Plate-ASTM A588 Gr.A/B.C/K-AGICO-ANSONASTM A588 Weathering Steel Plate. ASTM A588 specifies high strength low alloy weathering steel for structural purposes, it includes 4 grades:Grade A, Grade B, Grade C, Grade K. For it has protective oxide film on steel surface, compared with ASTM A36 and ASTM A572-50, it has better cossrosion resistant characteristic, use ASTM A588 steel plate instead of common carbon ASTM A588/A588M Weathering resistant steel ,A588 steel
