Such atmospheric corrosion resistant elements as Cu, cr, and Ni are added to structural steel to increase both weather and corrosion resistance.
铜、铬、镍等大气耐腐蚀元素被添加到增加天气、耐蚀钢结构。
So that, the dual-phase treatment may be the effective way for development of high strength, high cold formability atmospheric corrosion resistant steel.
