In hot work applications where thermal fatigue, mechanical shock, and dimensional precision are critical, H13 / 1.2344 tool steel has earned its reputation as a reliable and high-performance material. With a perfect balance of hardness, toughness, and thermal resistance, it is ideal for hot forging molds, die-casting molds, and extrusion tooling.
SAKYSTEEL supplies a wide range of H13 forged round bars and mold blocks that meet international standards such as AISI H13, DIN 1.2344, and JIS SKD61. All products are forged with controlled parameters to ensure internal soundness and long service life.
Many customers choose H13 mold steel blocks from SAKYSTEEL for aluminum die casting, where the tool must withstand repeated exposure to molten metal and high injection pressures.
H13 / SKD61 / 1.2344 is widely used in:
Forging H13 requires a starting temperature of 1050–1150°C and should be completed above 850°C to avoid internal cracking. Adequate deformation (over 60%) is key to closing central porosity. SAKYSTEEL uses radial and quick forging methods to enhance internal grain flow and reduce segregation in H13 forged bars.
For high mold performance, preheat at 850°C, austenitize at 1020–1040°C, and temper 2–3 times. Avoid overheating during quenching. Proper post-machining stress relief helps prevent tool cracking in service.
Use sharp carbide tooling and reduce feed rate when nearing final dimensions. For mirror-finish applications, H13 steel molds are suitable for polishing and EDM finishing.
SAKYSTEEL ensures every delivery meets strict mechanical and dimensional standards, allowing customers to reduce downtime and increase productivity. For full details, check our H13 mold steel product page.
