H13 tool steel plate is a chromium-molybdenum-vanadium hot work tool steel known for high toughness, good thermal fatigue resistance and wear resistance at elevated temperatures. It is widely used for die casting dies, extrusion tools, forging dies, hot shear blades and mold components. H13 steel plate can be supplied annealed for machining and heat-treated to required hardness after final processing.
Materials can be cut to required sizes according to customer specifications or project needs.
Different surface finishes can be supplied according to product type and application requirements.
Processing services such as cutting, machining, heat treatment or surface finishing can be arranged upon request.
Products are packed for international transportation with flexible delivery support for global buyers.
For high-temperature molds, die-casting molds, and hot-working tools.
Suitable for aluminum die-casting molds, hot forging dies, extrusion dies, hot-shearing tools, high-temperature components for plastic molds, mold inserts, and more. Ideal for mold applications requiring high-temperature strength, resistance to thermal fatigue, and wear resistance.|

Q: What is H13 hot work tool steel plate?
A: H13 plate is chromium‑molybdenum‑vanadium hot work tool steel mainly used for high‑temperature mould manufacturing. It features excellent thermal‑crack resistance and keeps stable mechanical performance under repeated heating‑cooling cycles.
Q: What equivalent grades and standards apply to H13 steel plate?
A: Our H13 steel plate follows ASTM A681 standard. Equivalent grades are GB 4Cr5MoSiV1, JIS SKD61 and DIN 1.2344. Mill test certificate covering chemical composition and mechanical properties is available for every batch.
Q: What thickness and processing options can you supply?
A: We provide H13 plates with thickness ranging from 10 mm to 200 mm. Hot‑rolled, forged and ESR refined plates are available. Saw cutting and custom size processing services are supported upon customer request.
Q: What are the main typical applications for H13 tool steel plate?
A: H13 plate is mostly used for aluminium and zinc alloy die‑casting dies, hot forging dies, hot extrusion dies, hot shear blades and high‑requirement plastic injection moulds needing good polishing performance.
Q: What is the delivery hardness and target hardness after heat treatment?
A: As‑delivered annealed H13 plate hardness is ≤235 HB for machining. After proper quenching and tempering treatment, the target working hardness reaches 48‑54 HRC with balanced toughness and heat‑fatigue performance.
