GB/T 4Cr13 Plastic Mold Steel
4Cr13 is a type of stainless steel that is commonly used in the manufacturing of plastic molds and other tooling applications. It is known for its high corrosion resistance, good polishability, and excellent wear resistance. This material is often used in the production of injection molds, extrusion dies, and other precision tooling components.

4.Heat treatment
Annealing:
-Heat to 750~800℃, with hold at minimum rate for 3 hours.
-Furnace cooling.
Stress relieving:
To be carried out after machining and before the final heat treatment.
Heating to 600~650°C for 2 hours.
Hardening:
Preheating to 600~700℃;
- Austenitizing at 990~1040℃
- Oil or thermal bath cooling at 500~550℃, then oil cooling according to the steel shape and size.
Quenched hardness: HRC 52~56
Tempering:
To be carried out after hardening according to the required hardness; at 170-270℃ in order to match hardness and resistance to corrosion; permanence for at least 2 hours;
Tempering must be repeated at least twice at a temperature 30 ℃ lower than the previous. Cooling in air.
