This month was published our new brochure Project Alfa PLUS:
Machine taps for ISO metric thread DIN 13
Grade of fit ISO 2 (6H)
- spiral point
form B: 4 - 5 threads leads
- helical flutes
form C: 2 - 3 threads leads
· New taps geometry
· Optimized steel type in taps production: HSSE and PM 30
· New production technologies
· New machines for tools production
· High treatment methods optimized
· High Tech - coating
PM 30 is a Co high alloyed powder metallurgy high speed steel. The high compressive strength, 67 HRC, and good abrasive wear resistance makes PM 30 suitable for demanding cold work applications and for cutting tools as an alternative to conventional Co-alloyed HSS.
The PM process gives a good machinability and grindability as well as a good dimension stability during heat treatment.
