Owing to its unmatched resistance to wear and tear, hardenability, and hot hardness, the H13 steel variety offers excellent thermal resistance. It also tolerates water cooling to some extent when put to use. Also, Nitriding the metal helps to improve its overall hardness. It even helps in diminishing resistance to shock in case the hardening layer gets considerably thick. And for the considerably fine structure and better homogeneity than its other peers, the machinability and tensile strength under high temperature make it a common use right about everywhere - from factory to forage.
The Best Properties
Some of the best features of H13 tool steel include:
- As a variety of versatile tool steel, mechanics can enhance by welding it with shielded metals, oxy-acetylene and shielded inert gases. However, to make the most of the metal, it is necessary to preheat, as well as post-heat the metal. It is also essential that the base metal goes with the filler. H13 tool steel's thermal fatigue, as well as high toughness, makes it ideal for various applications for hot work tools.
- The tool steel contains molybdenum and chromium. This makes it possible for cold and hot tool applications owing to their exceptional properties. Its impressive hot hardness means that it gives excellent resistance to cracking due to thermal fatigue. This can be the go-to pick for any mechanic for various tooling applications for hot work. This makes it one of the most popular tool steels in this market.
- H13 tool steel is also suitable for tooling that requires cold work. This is due to its properties to resist wear and tear.
Some of its other properties include:
- Good toughness on the colour of the steel.
- Strong scaling capability.
- Excellent resistance to impact.
The Available Varieties
The H13 steel tool variety comes in two wide varieties:
- VAR or Vacuum-Arc-Remelted.
- ESR or Electro Slag Remelted.
Typically, these steel mills follow the smelting procedure for advanced-quality tool steel. This includes vacuum cleansing furnace processing, vacuum smelting, remelting of electro slag and powder slaying. This helps in reducing the inclusion of toxic elements in steel. Also, the procedure of remelting provides better homogeneity in chemicals. It also refuses the carbide content in steel. Moreover, it improves the capacity of resistance to wear and tear and also improves the mechanical properties.
Applications for Every Utility
Among its various applications, H13 tool steel is most commonly found in die casting, as well as plastic moulds, as well as die casting. It has the capability to tolerate fast cooling right after very high temperatures for operation. It is also a good choice for the thermoplastic dies. The properties of H13 tool steel make it outperform the other popular choices, including 4140.
Common Application Examples
H13 tool steel finds its applications in extrusion and plastic moulding. The part involves dies, backers, die-holders, liners and stems, as these are copper alloys with rich aluminium and magnesium content. As a plastic modelling tool, it is used in the compression of injection moulds and transfer moulds with an HRC of 50-52. H13 Is an outstanding die steel for die casting and is also employed successfully for slides and cores in tool assemblies.
Examples of Very Common Applications
Premier India-based suppliers like TGKSSK supply H13 tool steels for various applications, including:
- Extrusion and forging dies.
- Cavities which are useful for casting dies.
- Wear resistant parts like automobile parts.
- The injection mould’s ejector pins.
- Shrunk rings for dies made from cemented carbide.
- Trimming dies.
- Short sleeves are used for die-casting.
From factories to forage, H13 tool steels tend to have their place just about everywhere.
