How much steel is recycled in the world each year?

Which is harder aluminum or steel?
Despite being at risk for corrosion, steel is still harder than aluminum. While aluminum does increase in strength in colder environments, it is generally more prone to dents and scratches than steel. Steel is less likely to warp or bend from weight, force, or heat.
