How to machine 65 Rc hardened steel? - Practical Machinist

Jun 23, 2005  Milling hard surfacing would be horrible. There's quite a difference between a flat even surface that is of 65rc, and a surface that is bumpy, uneven, warped? and the hardness is probably not perfectly even. Much different grain structure also. It would be hell on the cutters. Unless you grind most of it and face mill it for the final touch.

Beginner’s Guide on How To Anneal Steel – Make It From Metal

It’s a solid way of making steel take many hours to cool. The ideal cooldown rate for annealing steel is about 70 F per hour, down to about 500 F. In other words, a piece of steel that’s cooling from 1500 F to 500 F should ideally take about 14 hours. Actual ideal times will vary by grade of steel, but that’s a decent rule of thumb.

How to Harden Steel With Motor Oil Sciencing

Hardening steel with motor oil is a way of performing what is called the case hardening of steel. Pure steel is actually too soft for many applications.
