Corten Ab A588 Steel Plate 6mm refers to a 6-millimeter-thick weathering steel plate conforming to the ASTM A588 standard, specifically within the Corten steel family (Corten A/Corten B). Below is a detailed technical overview in English:

Chemical Composition (ASTM A588/Corten B Typical Values)

Element	Content Range	Role in Corrosion Resistance
Carbon (C)	≤0.19%	Controls hardness and weldability
Silicon (Si)	0.30–0.65%	Enhances oxidation resistance
Manganese (Mn)	0.80–1.25%	Improves strength and hardenability
Copper (Cu)	0.25–0.40%	Promotes patina formation
Chromium (Cr)	0.40–0.65%	Stabilizes the protective oxide layer
Vanadium (V)	0.02–0.10%	Fine-tunes grain structure for strength
Nickel (Ni)	≤0.50%	Enhances toughness in low temperatures
Phosphorus (P)	≤0.04%	Improves corrosion resistance (via solid solution)
Sulfur (S)	≤0.05%	Minimized to reduce hot cracking risk
