We offer Hot Die Steels available in various sizes, shapes and finish to suit varied requirements of our valued clients. These are procured from trusted vendors of the market who make use of better quality processing and servicing properties to manufacture quality range of Hot Die Steels.
We hold specialization in offering our clients an expansive range of Hot Die Steels, which is acknowledged for its load bearing ability and durability. These high quality products are widely used in forged dies, die casting dies, aluminum extrusion dies, bolt dies, hot piercing punches and for forming punches. Our range exhibits better processing and servicing properties as compared with steels in forgings.
1.Hot Die Steel ( H-11 Steel )
H-11 is 5% Chromium Hot Work Tool Steel. H-11 Steel has high hot tensile strength and toughness. It has good thermal conductivity and insusceptibility to hot cracking. H-11 can be water-cooled to a limited extent. Applications : Hot–work tool steel for universal use. Pressure casting dies and metal extrusion tools for processing light metals, forging dies, moulds, screws and barrels for plastic processing, shrink rings, hot-shear blades. Sizes Available : Rounds , Flats and Squares.
- Unmatched thermal conductivity
- Insusceptibility to hot cracking
- Can be water-cooled to a limited extent
2.Hot Die Steel ( H-13 Steel )
H-13 is 5% Chromium Hot Work Tool Steel with higher Vanadium. H-13 is an air hardening tool steel which combines a very good red-hardness with toughness and covers a wide variety of applications. H-13 hot work tool steel may be water cooled in service and gives high temperature strength and wear resistance. Applications : Hot-work tool steel for universal use. Pressure casting dies and metal extrusion tools for processing light metals, forging dies, moulds, screws and barrels for plastic processing, nitride ejectors, hot-shear blades. Sizes Available : Rounds , Flats and Squares.
- Die casting dies
- Extrusion dies
- Hot forging dies
- Hot gripper & heading dies
- Hot work punches
- Hot shear knives
3. Hot Die Steel ( H-21 Steel )
H-21 is 9% Tungsten hot work tool steel. H-21/1.2581 Hot Work tool Steel was developed to extend the life of aluminum die cast moulds. Used for hot-working dies and tooling such as die casting, extrusion and hot forming of parts. This alloy is one of the Hot Work, tungsten containing tool steels. The tungsten content is beneficial for hot strength at red heat, although toughness is somewhat reduced. Applications : Tools for metal tubes & rods, extrusion. Presses, rams, forging dies etc. Sizes Available : Rounds. Dia and Length are as per clients request.
