Hot rolled grinding steel balls Using rolling process will not increase production cost

Apr 05, 2021

Apr 04, 2018 COLD-ROLLED STEEL. As you might suspect, the manufacturing process behind cold-rolled steel is a bit different. Despite the name, this process refers to steel that is pressed with the pressure of a roller at room temperature. Compared to hot-rolled steel, cold-rolled steel has a nearly 20% increase in strength through the use of strain hardening
