Hi,
I have been looking for a supplier of power hammer dies and a machining/blacksmithing shop within a reasonable distance replied with an offer to make them. They seem professional and all but the material they told me they usually make the dies out of is O2 steel. This surprised me a bit as I have been thinking to have them made out of 4140, 4340 or some H or S steel for the right price.
Given the price is reasonable and they would do a proper heath treatment, is there any reason not to have them made out of O2 steel?
My power hammer is an old leaf spring hammer with 40kgs ram do not think this matters much, though.
Thanks for any help.
