Hongxin - Model DIN 1.2343 -Hot Work Tool Steel for Plastic Molding
DIN 1.2343, also known as X37CrMoV5-1, is a versatile chromium-based hot work tool steel widely used in tooling and high-temperature industrial applications. It exhibits excellent impact toughness and resistance to thermal fatigue cracking, making it ideal for applications such as hot work tooling, plastic molding, aluminum and non-ferrous metal processing, and high-pressure die casting. This steel can be deep-hardened by heat treatment and air quenching, which minimizes size alteration during heat processing and enhances its stability during repetitive thermal cycles. Featuring a chemical composition that includes chromium, molybdenum, and vanadium, it can withstand stresses and thermal shocks effectively. Its typical mechanical properties, influenced by different heat treatments, include high tensile and yield strength, hardness, and impact values. The typical processes like Electro-Slag Remelting (ESR) enhance its cleanliness and uniformity. Delivery conditions range from hot rolled, annealed to rough turned, depending on the product specifications and customer requirements.DIN 1.2343 material is a versatile and reliable choice for a wide range of industrial applications, particularly in hot work and high-temperature environments. Its excellent properties make it a preferred material for tooling and components that require high performance and durability.Hot Work Tooling, Aluminum and Non-Ferrous Metal Processing,Plastic Molding,High-Pressure Die Casting and General Engineering Applications are all its application.

- DIN 1.2343(X37CrMoV5-1) introduction
DIN 1.2343(X37CrMoV5-1) tool steel is a 5% chromium hot work tool steel that is represented by its excellent impact toughness. Chromium hot-work tool steels are designated as group H steels according to the AISI classification system, and specified in ASTM A681standard. The most commonly used chromium hot-work steels are DIN 1.2343(X37CrMoV5-1) tool steel, H12 tool steel, and H13 steel, within the series from H1 to H19.
DIN 1.2343(X37CrMoV5-1) tool steel is a deep-hardening, air-hardening steel and DIN 1.2343(X37CrMoV5-1) alloy steel could be deep hardened by heat treatment and air-quenching. That gives minimal size change during heat treatment. DIN 1.2343(X37CrMoV5-1) hot work steel also has super resistance to thermal fatigue cracking and superb resistance to gross cracking and thermal shock when water cooled in service.
- DIN 1.2343(X37CrMoV5-1) steel mechanical properties
The mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction, hardness, impact value, non-metalic inclusion etc. Different heat treatment, the mechanical properties will be different, such as normalized, tempered, QT. If you want to know the properties, kindly contact the salesman.
- Heat treatment
Annealing
Slowly heat to 843 – 898(1550-1650 F) then slowly Cool to 538(1000) in heat treatment furnace. Then frosty in make public. After annealing hardness HBS: 235 Max
Hardening
DIN 1.2343(X37CrMoV5-1) steel having enormously high hardenability and should be hardened by cooling in yet appearance. The use of a salt bath or controlled mood furnace is desirable to minimize decarburization, and if not user-simple, pack hardening in spent arena coke is suggested. The temperature employed is usually 1800-1850F, depending upon size section.
Quenching
Quenching temperature / ℃ | salt bath furnace: 996
Quenching temperature / ℃ | controlled atmosphere furnace: 1010
The heat preservation time/min: 5 ~ 15
Quenching medium: air cooling .
Tempering
Tempering temperature / : 552
After tempering hardness HRC or future: 52
- Delivery condition
For hot forged or hot rolled bar, usually the delivery condition is hot forged or rolled, annealed, rough turned.
For hot forged plate, usually the delivery condition is hot forged, annealed, milled surface.
For hot rolled plate, usually the delivery condition is hot rolled, annealed, black surface.
