Drill Rod Hardness and Machinability. The rods are manufactured of annealed tool steel (O-1, A-2, D-2, H-13, S-7, M-2, or W-1). Then they are cold drawn and (usually) polished. The drill rod hardness is affected by the cold drawing manufacturing process. The hardness is greater for the small diameters as show by the table below.
Get Price2021-6-5 · Second is the hardness scale which uses the Rockwell scale which I've looked into a bit. The stainless rating for 304 is 88, but the rating for hot-rolled is B76. For cold-rolled, it seems to be broken into two: Hot rolled is B67-B80 and cold drawn is B80-B90. This confuses me even more because this looks like the steel is cold rolled hot rolled?

Get Price2020-3-27 · Hot-rolled steel is weaker than cold-rolled, but it’s also cheaper since it doesn’t go through the second production process. However, this doesn't automatically mean cold is better just because it's stronger and more expensive. The more significant difference in how to use it is how specific your material needs are.
Get Price2018-12-27 · CRS vs. 304 Stainless Steel. The difference between CRS and 304 stainless steel is that CRS is a process and 304 is an alloy. Steel, hot or cold rolled, will rust and corrode. It is used in applications where that is not a consideration. Stainless steel is an alloy with chromium and nickel that prevents rust and corrosion.
Get Price1018 Cold Finished. Most cold finished bars are produced by cold drawing oversize hot rolled bars through a die. The cold reduction of the bar results in significantly improved mechanical properties, with a smooth surface finish to close tolerances. The cold working of the bar likewise improves machinability, usually rated at 76.
