H13 Tool Steel Powder
H13 Tool Steel Powder Supplier and Exporter
H13 Tool Steel powder (T20813) is a argon gas atomised hot-work tool steel feedstock for additive manufacturing, supplied to ASTM A681 for the wrought equivalent in 5-25 µm, 15-45 µm, 15-53 µm, 45-105 µm, 53-105 µm, 45-150 µm, 53-150 µm size fractions.
Holds hardness at temperature and resists thermal fatigue, so it survives the heat-and-quench cycling that destroys ordinary tool steel in die casting.

What Properties Does Printed H13 Reach?
Printed properties depend on the heat treatment, not just the alloy, so they are given per condition.
| Condition | Tensile strength | Yield strength | Elongation | Hardness |
|---|---|---|---|---|
| As built | 1700-1900 MPa | 1400-1600 MPa | 1-3% | 50-55 HRC |
| Hardened and double tempered | 1500-1800 MPa | 1300-1500 MPa | 5-10% | 44-52 HRC |
A preheated build plate, typically 200 C or above, is normally required to stop solidification cracking in the martensitic structure.
Which Processes Can H13 Powder Be Used In?
| LPBF | EBM | DED / cladding | MIM | Binder jetting | Thermal spray |
|---|---|---|---|---|---|
| Yes | Not applicable | Yes | Yes | Limited | Yes |
What Is H13 Powder Used For?
Die-casting dies, hot forging tooling, extrusion dies, and repair cladding of worn tool surfaces.
Post-processing
Preheated build plate to control cracking, then austenitise, quench and double temper.
Should I use H13 or maraging steel powder?
Use H13 where the tool runs hot and cycles, as in die casting, hot forging and extrusion, because it holds hardness at temperature and resists thermal fatigue. Use maraging 18Ni300 for injection mould inserts, where you want extreme hardness, easy machining before ageing and almost no distortion during it. H13 for heat, maraging for hardness and dimensional stability.
Characterisation and Packing
Each batch is supplied with chemical analysis, particle size distribution by laser diffraction to ASTM B822, apparent and tap density, and flow rate by Hall or Carney funnel. Morphology imaging, oxygen and nitrogen analysis and reporting to ISO/ASTM 52907 are available where your qualification requires them.
Powder is packed under argon in sealed containers with desiccant, labelled with lot number, alloy, particle size cut and date of atomisation.
