Weathering Resistance: Contains Cr (0.40–0.80%), Cu (0.25–0.55%), and P (≤0.035%) to form a protective oxide layer, 2–8x more corrosion-resistant than carbon steel.
Chemical Composition: C ≤0.16%, Si ≤0.50%, Mn 0.50–1.50%, S ≤0.035%, N ≤0.009% (when added).
Dimensions & Forms:
Thickness: 1.2–150 mm; Width: 1,220–4,200 mm; Length: 5,000–18,000 mm (custom cuttable).
Available as plates, sheets, coils, H-beams, bars, etc.; finishes: hot-rolled (HR), cold-rolled (CR).
Mechanical Properties:
Tensile strength: 510–680 MPa; Elongation: ≥16% (50 mm gauge); Impact test at 0°C.
Applications: Ideal for outdoor/harsh environments: bridges, shipping containers, marine structures, railway vehicles, and outdoor sculptures.
