Plastic Mold Steels
NAK80
- Welding
As a result of low carbon content, age hardening, and the availability of NAK
weld rod, hardness is lowered in the heat-affected zone during the welding
process, NAK 80 can be re-aged to 40 HRc with no distortion or stress put into
the mold. Polish, texture and wear in welded area are indistinguishable from
adjoining "parent steel" on the finished product.
- Machining
Machines to a superior surface with negligible dimensional change up to 20%
faster than P20. Positive rake cutters with concave, chip breaking inserts
work best, and last up to twice as long as P20 mold steels.
- EDM
The soft recast layer (approximately 32 HRc) is much thinner and is easier to
remove than steels with a recast layer that is equivalent to their "as
quenched" hardness. With NAK80, no post EDM stress relieving is ever needed.
- Stability
Age hardening eliminates the stresses inherent in quenched and tempered
steels. NAK80 is dimensionally stable and predictable over many years of
heating and cooling cycles.
- Surface Enhancements
Super clean steel with uniform grain structure facilitates superior nickel,
chrome, titanium, and other coatings. Unique chemistry responds extremely well
to ion nitriding.
- Texturing and Polishing
Exceptionally clean steel with uniform grain structure polishes beautifully
allowing superior texturing and photo etching.
- Wear
Higher hardness ensures molds have a longer life than those made from P20,
particularly in gate, runner, and parting line areas.
