PURPOSE: High-strength corrosion resistance steel and a method for producing the same are provided to obtain tensile strength which is higher than 800MPa and minimally reduce the content of an expensive alloy element. CONSTITUTION: High-strength corrosion resistance steel consists carbon 0.06~0.10 weight%, silicon 0.3~1.5 weight%, manganese 0.3~2.5 weight%, phosphorus 0.05~0.10 weight%, chrome 0.3~0.5 weight%, copper 0.2~0.5 weight%, nickel 0.1~1.0 weight%, aluminum 0.01~0.05 weight%, boron 0.001~0.05 weight%, the rest composed of the iron and impurity. The high-strength corrosion resistance steel additionally contains molybdenum and titanium. |
