Mechanical Properties of Tool Steel in the Annealed state
Mechanical Properties of Tool Steel in the Annealed state
(OP)
Hello, my employer has just purchased new simulation software. I have been working on a project to Coin or Hob tool steel. Within this software there is a tool steel library, but the chemical properties given seem to be in the hardened state of the tool steel. I have contacted our steel vendor and the information they sent me was also for tool steel in the hardened state. Can anyone help me with determining what the mechanical properties are for S7, D2, and M2 in the soft annealed state or where I may be able to find this information if it even exists? Appreciate any feedback, Tyson

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

Data sheets will show the maximum annealed hardness (usually around 255 HBW). You can use converters (e.g. on efunda.com) to find ultimate tensile strength. For annealed material, the ratio of yield strength to tensile strength usually is 0.6.

I read up on the subject and learned something new. Of course, based on what I read a more accurate term would be "cold hobbing". I'm also curious as to which area of manufacturing was first to use the term hobbing, tool/die makers or gear makers?
