Product Selling Points


H13 hot-work tool steel plate with chromium-molybdenum-vanadium alloy composition, exhibits outstanding hot hardness and thermal-fatigue resistance under cyclic high-temperature working conditions.

Excellent heat-shock resistance and good tempering stability, resists thermal cracking during repeated hot-forging, die-casting and hot-extrusion production cycles.

Fine homogeneous microstructure, good hardenability, delivers balanced strength, toughness and wear resistance after heat treatment, suitable for heavy-duty hot-working mold base and cavity inserts.

Good machinability in annealed state, supports laser cutting, water-jet cutting and custom blank processing, helps customers shorten mold-making cycle.

Strict metallurgical quality control, ESR-remelted high-cleanliness grade optional, full mill test certificates available, widely applied for aluminum die-casting molds, hot forging dies and hot extrusion tooling.

- FAQ -

Q1. What is H13 hot work tool steel plate 

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.

Q2. What equivalent grades and standards apply to H13 steel plate

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.

Q3. What thickness and processing options can you supply 

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 requestMade-in-Ch....

Q4. What are the main typical applications for H13 tool steel plate

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.

Q5. What is the delivery hardness and target hardness after heat treatment 

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.
