    Recycling of iron & steel SlideShare

    18-09-2014· IRON & STEEL (CONTINUED) Steel is an alloy of iron produced by refining iron to remove excess carbon and other elements, particularly silicon and phosphorus. The carefully controlled amount of carbon and other elements which are left, and some aluminum, nickel and chromium which may be deliberately added, determine the steel’s properties and therefore it’s applications.
