SKD11 chemical composition
SKD11 is a high-performance air-hardening die steel that is widely used in industrial applications around the world. It is produced using an electric arc furnace and then remelted through electroslag refining, which ensures high purity and excellent mechanical properties. This process results in improved toughness, a uniform microstructure, and superior resistance to high-temperature fatigue. The steel can endure sudden temperature changes and is ideal for long-term operation under high-temperature conditions.
SKD11 offers exceptional cutting and polishing performance, making it a preferred choice for precision tooling. Its recommended quenching temperature is 1020°C, which helps achieve optimal hardness and durability. Due to its outstanding characteristics, SKD11 is considered one of the best materials for manufacturing large and medium-sized aluminum alloy die-casting molds.
The chemical composition of SKD11 includes the following elements:
Carbon (C): 1.50%
Silicon (Si): 0.25%
Manganese (Mn): 0.45%
Chromium (Cr): 12.00%
Molybdenum (Mo): 1.00%
Vanadium (V): 0.35%
Phosphorus (P): ≤0.025%
Sulfur (S): ≤0.01%
This alloy is particularly well-suited for applications that require high strength and wear resistance. It is commonly used in the production of cutting tools, such as shears, circular saw blades, trimming dies, and wire drawing dies. Additionally, it is ideal for manufacturing components like milling cutters, impact dies, forming rollers, and precision gauges.
SKD11 is also frequently employed in the manufacturing of cold-pressing tools with complex shapes, mandrels, and various types of molds, including those used in the metallurgy, tin casting, and plastic industries. It is especially popular for screw head molds and other specialized forming tools. With its combination of toughness, hardness, and thermal stability, SKD11 remains a top choice for demanding industrial applications.
