Fushun Special Steel H13 die steel is the most widely used die-casting mold steel. Due to its relative advantages, stable quality and low price, it has won the trust of our customers. So what do you need to pay attention to when using H13 die steel?
1.H13 die steel has high hardenability, so it is deformed due to the use of medium with less cooling intensity and less heat treatment during heat treatment.
2.H13 die steel has high resistance to hot cracking and heat fatigue resistance, and can be water-cooled, so that the mold is not easy to form cracks and the cracks formed are not easy to expand, so as to avoid mold failure.
3.H13 die steel has high thermal softening ability and high temperature wear resistance, carburizing or nitriding process can be used to improve its surface hardness, Pengcheng die steel technicians said that it is necessary to pay attention to slightly reduce the thermal cracking resistance, in order to maintain a certain high temperature strength and dimensional stability.
4.Suitable heat treatment process: The heat treatment process of H13 die steel has a significant impact on its properties. In order to ensure the best performance and longevity of the mold, parameters such as heating temperature, holding time and cooling rate should be strictly controlled. It is recommended to carry out heat treatment operations under the guidance of professional heat treatment technicians.
5.Suitable cutting conditions: The machinability of H13 die steel is relatively good, but it is still necessary to choose the right cutting tool, cutting speed and cutting fluid. Too high cutting speed and too low cutting fluid concentration may lead to an increase in cutting force and cutting heat, which can affect the surface quality and accuracy of the mold.
6.Correct mold design: The mold design should fully consider the performance characteristics of H13 mold steel, such as thermal expansion coefficient, thermal conductivity, etc. Reasonable mold structure design, wall thickness distribution and cooling system design will help to improve the heat resistance, wear resistance and service life of the mold.
7.Timely maintenance and maintenance: During use, the wear and tear of the mold, surface quality, etc. should be checked regularly, and repaired and maintained in time. For molds that have been worn, they can be repaired by grinding, polishing and other methods to improve their service life.
In short, Fushun special steel H13 die steel, as a widely used die-casting mold steel, can only give full play to its advantages and improve the performance and life of the mold only by fully understanding its performance characteristics and taking correct use and maintenance measures.
