FAQ

H13/1.2344 steel is a high-performance hot-work die steel with high quenching ability and high toughness, capable of withstanding large impact loads. It also exhibits excellent thermal crack resistance, maintaining stable performance at high temperatures. Its wear resistance is moderate, which can be enhanced by carburizing or nitriding processes. Additionally, it has resistance to softening at higher temperatures, but attention should be paid to the upper temperature limit to avoid rapid hardness decrease.

Due to its excellent properties, H13/1.2344 steel has wide applications in multiple fields. It is primarily used in mold manufacturing, such as plastic molds, stamping dies, and die-casting molds, suitable for producing high-load molds and mechanical parts. Furthermore, it is used in forging, including large forging molds, hot forging dies, and cold forging dies. In the field of hot-work dies, it is also widely applied in aluminum and copper alloy die-casting molds, hot extrusion molds, etc. Additionally, the aerospace industry uses H13/1.2344 steel to manufacture critical components due to its high strength and good heat resistance.

The heat treatment process for H13/1.2344 steel includes preheating, heating, soaking, cooling, and tempering. Preheating involves heating the steel to approximately 500~600°C to eliminate internal stresses. Heating entails raising the steel to 1000~1050°C and maintaining it for a period to dissolve carbides and evenly distribute alloy elements. Soaking is done at a constant temperature for a period to ensure complete internal structure transformation. Cooling typically uses oil or water to bring the steel to room temperature, obtaining the desired mechanical properties and microstructure. Tempering is conducted at a temperature of 500~700°C to adjust hardness and toughness.

To prevent cracking in H13/1.2344 steel during use, it is crucial to strictly control the chemical composition, ensuring low levels of harmful elements like phosphorus and sulfur. Additionally, optimizing the heat treatment process by following correct steps and parameters is essential to avoid structural defects caused by overheating or overcooling. Rational mold design, avoiding stress concentration areas, and using rounded transitions to distribute stress are also key. Furthermore, enhancing mold maintenance by regularly inspecting for wear and damage, and promptly repairing or replacing damaged parts, are important measures to prevent cracking.

For the maintenance and care of H13/1.2344 steel molds, several precautions should be taken. Firstly, regularly clean the mold surface to remove dirt and oil, keeping it dry and clean. Secondly, apply rust prevention treatment by coating with a rust inhibitor when not in use for extended periods to prevent mold rusting. Store in a dry and well-ventilated environment, avoiding contact with moisture or corrosive substances. Regularly inspect the mold for wear and damage, taking prompt measures for repair or replacement. Lastly, follow correct usage methods and operational specifications to avoid mold damage caused by overload or improper operation.
