Plastic Mold Steel
Plastic Mold Steel
China3Cr17NiMo is a new type of plastic mold steel designed based on the advantages and disadvantages of Swedish S-136 and German 1.2316 steel.It is particularly suitable for thermoplastic corrosive plastics, applicable toHigh Temperature Wear-Resistant TypeMolds, suitable for transparent, mirror products and molds.Element.The elements are controlled with Cr at 15.50-17.50, Ni at 0.50-1.00, and Si, Mn at 0.40-0.60..
1. Pre-Hardening Tempered Plastic Mold Steel,2. Excellent corrosion resistance, 3. Excellent wear resistance and toughness, 4. Good thermal fatigue resistance, 5. Uniform material hardness, superior polishing performance, 6. HighSurface Precision,7. Low impurity content, stable production during the same period,
According toASTM E45 Method A, A sulfides ≤0.5, B oxides, C silicates, and D spheroidal oxides each ≤1 or DIN 50602-K1 ≤10 or according to customer requirements.
Using the process of smelting by Electric Arc Furnace (EAF) + Ladle Refining (LF) + Vacuum Degassing (VD) + Electroslag Remelting (ESR).Heat Treatment
(
(1) Soft Annealing - 780-820℃, furnace cooling, hardness HB ≤230.
(2) Quenching - 1020-1050℃, oil cooling or quenching liquid cooling, hardness HRC ≥45.
(3) Tempering - Temperature (℃): 100 200 300 400 500 600.
Hardness (HRC): 49 47 46 46 47 32.
Mechanical Properties
Heat Treatment System:1030℃ oil quenching, 780-800℃ tempering.

Performance
(1) High purity, excellent mirror polishing.
(2) Strong corrosion resistance, its corrosion resistance exceeds S-136..
(3) Convenient heat treatment, after tempering and pre-hardening, size stability.
(4) Wear resistance can also match S-136, and is easy to weld.
