I saw your post and no replies. I was wondering what you experience was 4 months ago with the A514 material. The Rockwell C hardness is 25-30, so that's reasonable to cut, but I have not cut it before. I am hoping it's not more difficult than 4140 HT which is 3-4 points higher in Rockwell but does not have nickel. Anything you can tell me is appreciated.
