A588耐候钢的化学成分

元素	典型内容 (%)	功能
碳 (C)	0.14 – 0.20	Provides hardness and tensile strength
锰 (锰)	0.50 – 1.00	Enhances strength and toughness
磷 (磷)	0.07 – 0.15	Promotes formation of a stable patina
硫 (S)	≤0.05	Improves machinability
硅 (和)	0.20 – 0.50	Acts as a deoxidizer and strengthens steel
铜 (铜)	0.25 – 0.55	Accelerates protective patina formation
铬 (铬)	0.40 – 1.25	提高耐大气腐蚀性能
镍 (在)	0.40 – 0.65	Enhances toughness and durability

A588 is designed to form a dense, reddish-brown protective oxide layer (铜绿) 那 prevents deeper corrosion 当暴露于室外环境时. Compared to A242, A588 offers higher strength and improved corrosion resistance, making it suitable for 结构和重型应用.
