Plastic Mould Steel PH42 ESR

Main Characteristic

PH42 ESR is a plastic mold tool steel in the class of Precipitation hardening steel.
Selling in the condition of hardening.Hardness approximately 36-40 HRC (1250 N/mm2)
Besides, this is produce by the method of Electro Slag Remelted which made it highest quality
for plastic mold Electro Slag Remelting process is done by bring in the steel from conventional
process and remelting through the slag in order to purify any contamination from the steel.
By this mean, the steel are in high cleanliness condition with small grain size.
Thus, result in high performance as PH42 ESR, obtain maximum strength and performance in
every aspect as compare to conventional steel in the same grade. To name, better wear resistance,
polishing ability, texturing property and ability in wire cut and EDM

OutStanding Properties

Remelting in Slag purifying to obtain maximum performance
high strength in selling condition (40 HRC)
Homogeneity throughout cross section in any area
Risk free from bend or damage from heat treatment process
Come with High tensile and strength
Easy to machining and well polishing ability


Application

PH42 ESR suitable for plastic mold and rubber mold. All include any type of plastic ,
thermo plastic , reinforce plastic , thermo setting and engineering plastic.
For thermo setting recommend to do nitriding which will suitable for injection molding ,
extrusion molding and compression molding.Especially when the mold need maximum
high strength or need high precision with minimum changinin in it size would required
Or in case of high volume production.
Besides this grade also fit for high polishing ability task such as Lens or EDM ,
Texturing which demand higher quality as compared to 2311 Tensile is in range 1250 N/mm2 ,
suitable for making part of mold in cold work which need high strength but avoid hardening
Such as Punch Holder Base Plate
