1. Core Advantages and Introduction of the Product
Dear customer, hello! Our factory provides long-term spot supply of high-quality H13 hot work die steel. H13 is a widely used chromium-molybdenum-vanadium medium alloy hot work die steel, with the national standard designation of 4Cr5MoSiV1. Due to its excellent thermal fatigue resistance, good wear resistance and toughness, as well as superior hardenability and thermal strength, it has become a material for manufacturing aluminum, zinc, and magnesium alloy die-casting molds, hot extrusion molds, and hot forging molds, and is known as the "evergreen tree" in the field of hot work die steel.
Excellent thermal fatigue resistance: It can operate under harsh working conditions involving alternating hot and cold cycles, resisting thermal stress cracks caused by repeated heating and cooling, thereby extending the lifespan of the mold.
Excellent comprehensive mechanical properties: It combines high high-temperature strength and good toughness, capable of withstanding impact loads and preventing early cracking of molds.
Excellent hardenability: It boasts an extremely deep hardening depth, ensuring uniform mechanical properties in the core of even large-sized modules.
Good resistance to solution loss: It exhibits good resistance to the erosion caused by molten metals such as aluminum and zinc.

III. Supply specification and form (customization supported)
Round bar/bar material: Diameter: Φ20mm - Φ600mm | Length: Customized according to size
Plate/flat steel: Thickness: 20mm - 800mm | Width: 200mm - 1500mm | Length: customized according to specific dimensions
Module/block material: We can provide large mold blanks and perform sawing, rough milling, and six-face grinding according to the drawings.
We offer professional heat treatment OEM services (quenching + tempering), and can provide pre-hardened finished products with different hardness levels (such as HRC48-52) according to your specific application requirements (such as die-casting and forging).
IV. Our Advantages
Excellent quality: Smelting is carried out using electric furnace + electroslag remelting (ESR) or vacuum degassing (VD) processes, resulting in pure material, uniform microstructure, good isotropy, and stable performance.
Complete specifications: We regularly stock round bars, plates, and large modules of various specifications, and are particularly adept at supplying large-sized die-casting mold blanks.
Price advantage: Direct supply from the manufacturer with clear channels, making us a reliable partner for your stable production.
Technical consultation: With an experienced technical team, we can provide advice on material selection and heat treatment processes for your mold projects.
One-stop service: From raw materials, rough machining to heat treatment, we can provide a one-stop solution to save you valuable time.
V. Application Fields
This product is the core material for manufacturing aluminum, zinc, and magnesium alloy die-casting molds, hot extrusion molds, hot forging molds, plastic mold frames, and all molds that operate at high temperatures.
