SKD11 is a kind of high carbon and high chromium cold work die steel, which is often used in the manufacture of high-precision molds, printer rollers, paper cutting blades, shearing blades, injection molds, etc.
This material has extremely high hardness and strength and can be used to make durable tools and molds. At the same time, it also has good corrosion resistance and thermal stability.
What is the hardness of SKD11?
The hardness of SKD11 steel is generally between 58-62HRC, which is a harder steel. Among them, HRC refers to an indicator of hardness testing, which is the hardness of a material measured from a surface depth of 0.001 inches.
The hardness of SKD11 is closely related to its high carbon and chromium chemical composition. High carbon content hardens steel, while high chromium content increases its wear resistance, making it more suitable for making wear-resistant molds and tools.
Here are some of SKD11's key data and features:
1, high temperature strength and toughness, good wear resistance, easy cutting;
2, SKD11 is a good strength, toughness and heat balance of hot die steel, in recent years with the development of isotropic products and increasingly to high toughness and other aspects of development, it can make the mold life longer, more stable performance, and easy to process, heat treatment deformation is small
1. Chemical composition:
- Carbon (C) content: 1.40-1.60%
- Silicon (Si) content: 0.30-0.50%
- Manganese (Mn) content: 0.60-0.90%
- Sulfur (S) content: ≤ 0.030%
- Phosphorus (P) content: ≤ 0.030%
- Chromium (Cr) content: 11.00-13.00%
Molybdenum (Mo) content: 0.60-1.20%
Vanadium V content: 0.20-0.50%
1. High hardness and strength. The hardness and strength of SKD11 are paimingqian, which is very useful in the manufacture of high-precision molds and tools.
2. Good corrosion resistance. Due to its high chromium content, SKD11 has good corrosion resistance and can adapt to wet or corrosive environments.
3. Good thermal stability. SKD11, after proper heat treatment, can maintain a stable hardness and strength, thus maintaining its performance in high temperature environments.
Overall, SKD11 is a steel with high hardness, strength and corrosion resistance, which is ideal for the manufacture of high-precision molds and tools. However, in use, it should be noted that due to its high hardness, the processing difficulty is correspondingly increased, and it is necessary to use high hardness tools for cutting and drilling.
SKD11 is a tool steel brand, more zhiming in the industry, the price is also higher. The steel is a kind of cold working die steel widely used in the world. Smelting by electric furnace and electroslag remelting, high purity, better toughness, uniform organization, has good high temperature strength, toughness and high temperature fatigue resistance, can withstand temperature changes, suitable for long-term work at high temperatures, with excellent cutting performance and polishing performance, quenching temperature 1020℃. It is the best material for making large and medium aluminum alloy die casting mold.
