Hot Work Die Steel

AISI H11 (DIN 1.2343) is one of the hot work chromium type tool steels belong to ASTM A681 standard. It has good strength in high temperature, excellent toughness and ductility in all z directions, excellent hardenability, and a high level of thermal shock and thermal fatigue resistance. AISI H11 steel can be deeply hardened by heat treatment and air quenching.

AISI H13 tool steel is characterized by its high hardness, wear resistance, toughness, and corrosion resistance. AISI H13 steel can withstand high temperature and high pressure loads. AISI H13 steel can reduce the tooling wear and improve production efficiency.

SKD61 Hot Work Die Steel is a medium alloy hot work die steel containing silicon, chromium, molybdenum and vanadium. After quenching and tempering treatment, it obtains a martensitic structure with fine structure and moderate grains. It is basically distributed with fine carbides and has good properties. It has comprehensive mechanical properties and good hardenability, which is more suitable for manufacturing molds with large sizes and complex shapes.The corresponding foreign brand of SKD61 steel is 4Cr5MoSiV1 steel、DIN 1.2344、ASTM H13

AISI H13 tool steel is characterized by its high hardness, wear resistance, toughness, and corrosion resistance. AISI H13 steel can withstand high temperature and high pressure loads. AISI H13 steel can reduce the tooling wear and improve production efficiency.

1.2343 steel is often used for highly stressed structural parts such as aircraft landing gear. lt resistssoftening at temperatures up to 537°C while retaining good ductility and toughness even atstrength levels on the order of 275 ksi.

H11/1.2343 tool steel is a high-strength, high-toughness hot-work mold steel with excellent heat resistance and hardness, widely used in manufacturing high-quality molds, mold components, and tools ‌. Compared to other types of steel, H11 tool steel exhibits superior comprehensive performance, especially at high temperatures, maintaining its strength and toughness even below 600℃ ‌[High Temperature Performance]‌. Its chemical composition includes chromium, molybdenum, and vanadium, which contribute to its high hardness and wear resistance. While H11/1.2343 tool steel can undergo heat treatment processes like quenching and tempering to enhance its hardness and strength, it may impact its plasticity ‌[Heat Treatment & Plasticity]‌. Overall, H11 steel is particularly suitable for manufacturing molds requiring high precision and complexity due to its superior deformation ability and workability ‌[Suitability for Complex Molds]‌ .

DIN 1.2344 Steel is pressure-resistant hot work die steel. DIN 1.2344 steel has been remelted by electro slag and has uniform material and good hardenability. DIN 1.2344 steel has excellent machining performance and polishing performance, high toughness and plasticity, good high and low temperature wear resistance, high temperature fatigue resistance and heat resistance.The corresponding trademark of DIN 1.2344 steel in other countries is H13 steel,SKD61 tool steel,GB 4Cr5MoSiV1.
