PowderRange® H13 is a versatile air-hardening, 5% chromium hot-work tool steel for laser powder bed fusion (LPBF). It combines high impact toughness, temper resistance and excellent thermal-fatigue resistance — the classic choice for die-casting and hot-forming tooling.
Processing note: like all high-carbon tool steels, H13 has challenging weldability in laser/electron-beam AM — part geometry and build parameters must be controlled (and preheat used) to avoid micro-cracking. For tooling where AM processability is the priority, ask us about M300 maraging steel as an alternative.
Why teams buy this powder from Additive Plus
- Genuine Carpenter PowderRange® H13 — gas-atomized for high sphericity, low oxygen and consistent flow.
- Available in small, workable volumes. Most mills sell large minimums and hide pricing behind an account. We stock this alloy and sell it in accessible quantities at a clear, published price.
- Full COA with every lot — particle size distribution, chemistry, apparent density and flow rate, with a traceable lot number.
- Fast dispatch from Los Angeles.
- Need a custom alloy or a tighter cut? We also run our own atomization in-house and can produce custom small-batch powder on request — separate from this stocked product.

Heat treatment & processing
- Air-hardening with low distortion; austenitize, then temper (typically a double temper) to the target hardness.
- Use platform preheat and validated parameters to control residual stress and avoid micro-cracking in the build.
- Stress relief before part removal is recommended.

What is H13 tool steel powder?
H13 tool steel powder is a 5% chromium hot work steel designed for additive manufacturing, offering high toughness and thermal fatigue resistance for tooling applications.
Which additive manufacturing processes are compatible?
H13 tool steel powder is primarily used with LPBF systems.
Is H13 easy to print in LPBF?
H13 can present weldability challenges in laser and electron-beam processes. Proper parameter optimization is required to reduce micro-cracking risk.
What industries use H13 tool steel powder?
It is commonly used in energy and industrial sectors for hot work tooling and high-temperature components.
What are typical applications?
Applications include extrusion tooling, die casting, molding tools, valves, pumps, and manifolds.
What quantity do you sell — can I order a small amount?
Yes. This is a stocked Carpenter PowderRange® alloy and we sell it in accessible quantities — a 10 kg bottle as standard, with 440 kg and 840 kg hopper sizes available for production runs. Most mills require large minimums and hide pricing behind an account; we keep it simple with a clear, published price and small-lot availability. Need a different volume? Just ask.
Do you provide a Certificate of Analysis (COA)?
Every lot ships with a full COA — particle size distribution, chemistry, apparent density and flow rate — plus a traceable lot number, so you can qualify once and reorder the same material with confidence.
