SKD11 chemical composition
SKD11 is a high-performance air-hardening die steel that is widely used across the globe. It is produced using an electric arc furnace and then refined through electroslag remelting, resulting in high purity, excellent toughness, and a uniform microstructure. This material offers superior high-temperature strength, impact resistance, and fatigue performance, making it capable of withstanding rapid temperature changes. It is ideal for long-term use in high-temperature environments and provides outstanding cutting and polishing properties. The recommended quenching temperature is 1020°C, which ensures optimal hardness and durability.
SKD11 is particularly well-suited for manufacturing large and medium-sized aluminum alloy die-casting molds due to its stability and performance under demanding conditions. Its chemical composition includes:
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 versatile steel is commonly used in a wide range of industrial applications, including but not limited to: precision cutting tools, sharp edges, scissors, circular saw blades, cold and hot trimming dies, roller edges, screw patterns, wire drawing dies, milling cutters, impact dies, round rollers, power transformer cores, cutting knives for rolling, steel tube forming rolls, special forming rolls, precision gauges, complex-shaped cold pressing tools, mandrels, metallurgical equipment, tin molds, plastic molds, screw head molds, and more.
Whether you're working on precision tooling or heavy-duty die-making, SKD11 offers a reliable and durable solution that meets the highest standards of performance and longevity.
