3Cr2W8V is a high-performance hot-work die steel widely used in the manufacturing of molds for die-casting applications. It is primarily supplied by No. 5 Steel Mill as round steel, with zero-cut options available. For inquiries or distribution details, contact us at 0510-85360327.
Standardized under GB/T 1299-2000, 3Cr2W8V has a uniform digital code A20502 and is commonly known as Grade 3Cr2W8V. Its chemical composition includes:
- Carbon (C): 0.30–0.40%
- Silicon (Si): ≤0.40%
- Manganese (Mn): ≤0.40%
- Chromium (Cr): 2.20–2.70%
- Tungsten (W): 7.50–9.00%
- Vanadium (V): 0.20–0.50%
- Phosphorus (P): ≤0.030%
- Sulfur (S): ≤0.030%
The steel is typically delivered in a normalized or annealed condition with a Brinell hardness (HBW10/3000) of ≤255–207. For heat treatment, it is quenched at temperatures between 1075–1125°C, using oil as the cooling medium.
Known for its excellent thermal conductivity, toughness, and high-temperature strength, 3Cr2W8V is ideal for high-stress, high-temperature applications. It contains significant amounts of carbide-forming elements like chromium, tungsten, and vanadium, which enhance its hardness, wear resistance, and thermal stability.
This alloy is commonly used in the production of molds for casting copper, aluminum, and magnesium alloys. It is suitable for components such as cores, sprue bushings, splitting nails, embossing tools, hot shears, forging dies, and flat forging molds.

Aluminum single -hanging window is a window type made of aluminum alloy material. The following are some introductions about it:
1. Structural characteristics:
-Forest frame: Made of aluminum alloy material, has high strength and stability, and can withstand greater weight and wind. The design of the window frame is usually relatively concise to achieve narrow -edge effects and maximize the lighting area and field of vision.
-Fan fan: Generally, there is only one fan fan. It can be connected to the window frame through the hinge or other connection devices to open out or inward. The size of a single -hanging window is relatively small to facilitate operation and control.
-The hardware accessories: including clubs, handles, locks, etc. The quality of these hardware accessories directly affects the performance and safety of the window. High -quality hardware accessories can ensure that the windows are opened and closed smoothly, and they have good anti -theft function.
2. Performance advantages:
-Beve sealing: Aluminum single -hanging windows usually use sealing materials or sealing wool strips such as sealing materials, which can effectively prevent the penetration of air, rain and dust, and improve the indoor insulation, heat insulation and sound insulation effects.
-Opered corrosion resistance: The material of aluminum alloy has good corrosion resistance, not easy to rust and corrosion, and can be used for a long time in various harsh environments. Even in high corrosive environments such as humidity, rain, or coastal areas, aluminum single -hanging windows can maintain good appearance and performance.
-The higher strength and hardness: The strength and hardness of aluminum alloy materials are high, and can withstand large external force impacts, and it is not easy to deform and damage. This makes aluminum single -hanging windows have good safety and stability, and can effectively protect the safety of indoor personnel and property.
3. Application scenario:
-Residential building: suitable for various residential buildings, such as villas, apartments, ordinary houses, etc. It can be installed in different rooms such as bedrooms, living rooms, kitchens, and bathrooms to meet different lighting and ventilation needs.
-A commercial buildings: There are also widely used applications in commercial buildings, such as office buildings, shopping malls, hotels, etc. It can be used as an outer wall window or indoor partition window to provide good lighting and vision for business space.
-Ex Industrial Building: In some industrial buildings, such as factory buildings, warehouses, etc., aluminum single -hanging windows can also be used as a window for ventilation and lighting. Because it has good corrosion resistance and strength, it can meet the requirements of the industrial environment.
