H13 Tool Steel Filament

H13 Tool Steel Material 200cm³


H13 Tool Steel is a tough, high-wear tooling steel suitable for demanding hot work applications. It is abrasion-resistant at low and high temps, and exhibits high strength at low and high temps, making it a great multi-purpose steel.

Markforged H13 Tool Steel is specially engineered for 3D printing with the Metal X. Parts can be used as-sintered, or they can be heat-treated to optimise their mechanical properties. As-sintered parts demonstrate a hardness of 40 HRC and a tensile strength of 1,420 MPa; heat-treated parts demonstrate a hardness of 45 HRC and a tensile strength of 1,500 MPa - an 11% and 5% increase respectively.

You can use H13 Tool Steel for forming, blanking, and tooling to create dies, punches, rollers, blades, plates, pressure pads, stems, rams, inserts and bending tools.

H13 is widely used in engineering and manufacturing applications, but it is also used in construction and industrial environments. It is low-cost, easy to machine, high-wear and can be repurposed, making it an extremely useful metal.

One of the most desirable characteristics of H13 Tool Steel is it resists thermal fatigue cracking as a result of heating and cooling cycles. The ability to withstand these cycles is why H13 is considered the best hot work tooling steel.

Markforged H13 meets the hardness requirements of ASTM E18. It achieves its greatest hardness and strength with double tempering at 600C. For this, you can use the Markforged Sinter 1, an oven specially designed for 3D printed parts.

    Many 3D printers lay claim to being ‘industrial-grade’ but when you delve into their material list, rarely do you find anything more durable than nylon.

    That’s where Markforged 3D printers differ. In the case of the Desktop and Industrial series 3D printers, these use nylon or Onyx as the base material (Onyx is a proprietary filament made by Markforged, it’s part nylon, part chopped carbon fibre). You can then reinforce prints with continuous strands of a stronger composite - carbon fibre, fibreglass, or Kevlar - to create truly industrial-grade prototypes and end-use parts.

    For example, parts printed in carbon fibre are stronger than 6061-T6 aluminium. The Desktop series includes the Mark Two, Onyx One and Onyx Pro, and the Industrial series the X7, X5, and X3. There’s a printer for every application.

    Then there’s the Metal X, Markforged’s greatest machine yet. This 3D printer utilises a process called ADAM (Atomic Diffusion Additive Manufacturing) to print parts in powdered metal surrounded by a plastic support. The parts are then sintered in a furnace externally to become solid. This enables you to manufacture metal parts with geometries and details that would be impossible with subtractive manufacturing processes.
