Hot rolled steel is more suitable for large structural components which do not have tight tolerances and aesthetic requirements. However, cold rolled steel will be the best choice if you need smaller parts requiring durable and more precise qualities. Cold rolled steel is also stronger and harder than hot rolled steel.

1D Stainless Steel Finish Hot Rolled, Annealed Pickled. After the steel is hot rolled in the mill, it is then put through a heat treatment called annealing. Annealing consists of heating the steel and letting it cool down slowly to remove internal stress and reduce hardness. This makes it more ductile and workable.

Cold Rolled is Hot Rolled that was rolled a second time while cold (atmospheric temp) which gets it to a more precise size and shape. Side effects of being Cold Rolled are that the mill scale pops off and the stock "work hardens". Many think that Cold Rolled is harder to forge because it is harder metal. It is only harder because it is "work ...
