Jig grind 4340 - Practical Machinist
In your first post you said 4340 at 56 RC. 4340 is neither exotic nor is 56 RC very hard. It& 39;s got a bit of nickel and chromium in it so its a bit shittier to grind than plain carbon steels, but not overwhelmingly so. However at 56 RC it& 39;ll hardmill just fine.
Hydrogen embrittlement of 4340 steel - Finishing
2001. It depends on the condition of the 4340 steel and the specific electroplating/pickling process. If the steel is hard, there is a great potential for hydrogen embrittlement when the process generates hydrogen at the steel surface as in most plating and pickling processes.

Heat treating 4340 Engineers Edge Forum www.engineersedge.com
What happens to the physical size of 4340 during heat treating? I have some shafts to machine from 4340 5-1/2" dia stock, to an average size of 5.000" dia x 18" long. Will the material grow or shrink and by how much? It will be quenched and tempered to 40-44 RC. Thanks for any help, Dave Cooke Amax Machining
Working With Titanium Alloys - Neonickel
To speed up the process of grinding titanium a perfect combination of grinding fluid, abrasive wheel and wheel speeds should be used. Using alundum and silicon carbide wheels at lower speeds along with a sodium nitrite mixture will help achieve the best finish possible.
