In the world of manufacturing and engineering, tool steel is a critical component that ensures the durability and efficiency of various tools and dies. Among the various grades of tool steel, H13 stands out for its exceptional performance in both hot work and cold work applications. This versatility makes it a preferred choice for industries that require high resistance to thermal fatigue, shock, and abrasion.
What is Pre-Hard H13 is an interesting one? H13 tool steel is a high-performance material that finds its place in hot work applications.
Here are the key points about it:
Composition and Properties:
- Chemical Composition: H13 steel contains around 5% chromium (Cr) along with molybdenum (Mo) and vanadium (V). These alloying elements contribute to its exceptional properties.
- Toughness and Hardenability: Molybdenum enhances toughness, while vanadium promotes the dispersion of hard vanadium carbides, resulting in excellent wear resistance.
- Secondary Hardening: H13 is a secondary hardening steel, which means it maintains high hardness and strength even at elevated temperatures.
- Applications: It’s widely used for hot work tools, especially in die casting (think aluminum and magnesium), where it battles thermal fatigue, erosion, and wear.
Physical Properties:
- Density: Approximately 7.76 g/cm³ (0.280 lb/in³).
- Specific Heat Capacity: Around 460 J/kg·K (20 °C) or 0.11 Btu/lb·°F (68 °F).
- Elastic Modulus: Roughly 193 GPa (28 x 10⁶ psi) at room temperature.
- Thermal Conductivity: Varies with temperature but hovers around 32.0 W/m·K (20 °C) or 18.5 Btu/ft·h·°F (68 °F).
- Coefficient of Thermal Expansion (CTE): Increases with temperature, ranging from 10.4 μm/m (20-100 °C) to 13.1 μm/m (20-650 °C).
Mechanical Properties (Typical values for tempered H13 steel):
- Tensile Strength: Around 1960 MPa (284 ksi).
- Yield Strength: Approximately 1570 MPa (228 ksi).
- Elongation: About 13.0% in a 4D gage length.
- Hardness: Typically measured in the Rockwell C (HRC) scale, around 46.2 HRC.
- Impact Toughness: Charpy V-notch impact strength is also relevant.
Applications:
H13 is commonly used in cores, cavities for dies, and other tools that require toughness and polishability.
Its stability during heat treatment makes it a reliable choice for various hot and cold work applications. Pre-Hard H13 tool steel, with its standard hardness of 460-500 Brinell Hardness Number (BHN), is particularly sought after. This pre-hardened state allows for immediate use in manufacturing processes without the need for further heat treatment, saving time and resources. It is commonly utilized for components such as ejector pins, apparatus holders, and shrink fit chucks, which are integral to the functioning of machinery.
The applications of Pre-Hard H13 are diverse, ranging from dies for drop forgings to aluminum and low-pressure die casting. It is also used in extrusion processes, containers and liners, punches, plugs, holders, and injection molds. These applications highlight the steel’s ability to withstand the rigorous demands of forming and molding processes.
