F-2 Tool Steel Equivelant

have you tryed your heattreatment supplier or local steel suplier for this info as most have a metalurgest on there payrolls?

I have tried that avenue with two different heat treaters, however they were not familiar with that specific grade. Thank you for your input though.

Any more details on application available?

I'll check my records and respond in the AM.

Our customers machine makes the powder that is used in powder coated paint. From my knowledge of the parts usage, the part they are asking us to replace is cylinder shaped with fins on the inside that spin at a high velocity to pulverize the powder media. Apparently the fins on the inside of this cylinder either are breaking from being too brittle or are being rounded by the media, so it takes longer to break down the media. This is using the current manufacturers supplied part for the machine.

We are hoping to find a tool steel that has very good abrasion resistance to machine these out of and then possibly have them titanium-nitride coated (If the tool steel used can be coated).

Hopefully this info will help more. Thank you all for your input.

F-2 designation is obsolete. it is same as t60602 in the uns system. High Carbon, Tungsten. Crucible used to sell it under the 'double special' brand name.

It was a water hardening cold work steel

Element Symbol Min. Max. Carbon C 1.2 1.4 Chromium Cr 0.2 0.4 Manganese Mn 0.5 Phosphorus P 0.03 Silicon Si 0.5 Sulfur S 0.03 Tungsten W 3.0 4.5

I am not surprised to find abrasion and wear, the question is over what length of time. We ran a high speed fan to provide draft for our dwight lloyd sintering plant and we had to metallize that fan every tuesday to replace metal worn off by dust strikes over the course of the prior six days...

What is the life of the current parts, and how does that differ from the anticipated design life ?

what is the section thickness? M-2, M-3 type 1 and M-3type 2 will both give through hardness deeply, so that even with the 'rounding' there is still hardness in the part to pulverise the material.

Not familiar with F-2.

I think M-2 gives pretty good wear & abrasion resistance & is readily available

hope it helps.

Good luck

Carpenter's book shows decent wear data for D-2 & D-3, D-3 being slightly better, but neither sound as good as the F-2.
