Difference between cold and hot rolled steel

Locksmithing, turning, milling, but also sheet metal working are some of the specialist areas that our new forum for metal working will be about.

Hello, a stupid question what is the difference between hot and cold-rolled steel. Thanks in advance

Hello,
In the other Fred there is actually quite a bit, whereby cold-rolled sheets can be rolled thinner than hot-rolling. So 0.5 mm sheet metal should not be hot-rolled, then it is almost gone
Perhaps it is interesting that cold-drawn steel does not have these ugly round edges, which do not necessarily look nice with joints (e.g. T made of flat iron) after plastering, since a 50 wide by 30 thick flat iron only has 50 mm in the middle.

Metals are made up of crystals. During cold forming, these crystals are deformed (compressed, etc.). The result is essentially a loss of elasticity and plasticity and an increase in hardness. If I have this in mind, it will be used consciously for piano strings, for example.
Mostly, however, you want to get the greatest possible elasticity and plasticity. (Components should deform before breaking instead of breaking spontaneously).
This is reduced or canceled by heating.
