Jim, I am open to applying hard coatings if the cost for small lots compares to a standard tool (wrench) heat treatment with comparable surface toughness. I am still looking for the standard in tool heat treatment so that I can price and compare. I thought that the spec. would be common...
Thank you for the info. I was trying to start a new thread to find the basic heat treatment for tools, but yes it is technically part of the old thread. I just have not found an answer and continue to research.
Regarding 4320, I will research your recommnedations further...thank you

Thank you for the reply. I agree..most tools are forged, but heat treated also...I am trying to learn more about this process and how to specify for custom one of a kind tools machined out of steel. A related question would be...how to attain the surface toughness of a forged wrench on a...
I am working with a machine shop to fabricate a specialized puller. The puller will see its fair share of hammer blows. I noticed that many of my wrenches, pullers, bearing splitters, etc. show very minor signs of wear, but have been abused for many years. I would like the puller to have the...
Thanks for the info...
The part is specialized therefore low quantity. The material type is 4140...the part will not be cast or forged. I am familiar with a heat treatment of a puller, involving high temperature then lye salt to temper or harden, but not sure if sufficient....investigating...
Hello...I need to specify the heat treatment, hardness, peening, etc of a basic three prong gear puller with 6 inch 'arms'....I have searched this site and the web and have not found much info. The design will go thru destructive testing, but I am trying to establish an engr. baseline. Several...
How does one machine miniature tubing, say .040 inch OD x .020 ID, without any burrs? Does industry use small cutoff saws or laser? There are many companies offering the service, but wondered if I can achieve the same in my shop without expensive machinery such as a laser. Thank you.
