SKD 11 Steel Supplier in India | High-Performance Cold Work Tool Steel
Introduction to SKD 11 Steel
SKD 11 steel is a premium, high-carbon, high-chromium cold work tool steel renowned for its exceptional wear resistance, edge retention, and high compressive strength. It is a go-to material for a wide variety of cold work tooling, prized for its ability to withstand severe abrasive conditions and its dimensional stability after heat treatment. At Jupiter Steels, based in Delhi, we are a trusted stockist and supplier of SKD 11 steel, providing top-quality material to businesses throughout India, including industrial hubs in Manesar, Haryana, and beyond.
Chemical Composition of SKD 11 Steel
The outstanding performance of SKD 11 tool steel is a direct result of its carefully balanced chemistry. The key alloying elements and their typical weight percentages are:
- Carbon (C): 1.40 – 1.60%
- Chromium (Cr): 11.00 – 13.00%
- Molybdenum (Mo): 0.80 – 1.20%
- Vanadium (V): 0.10 – 0.40%
- Silicon (Si): 0.20 – 0.50%
- Manganese (Mn): 0.20 – 0.50%
Functioning and Reasoning of Chemical Elements
- High Carbon & Chromium: The combination of high carbon and very high chromium content is the defining feature of SKD 11 steel. Together, they form a large volume of extremely hard chromium carbides. These carbides are what provide the steel with its extraordinary abrasion resistance and ability to maintain a sharp edge, making it perfect for long production runs.
- Molybdenum (Mo) & Vanadium (V): Molybdenum adds to the steel’s hardenability and wear resistance. Vanadium forms its own carbides, which further boost the steel’s resistance to wear and abrasion, which is essential for tooling.
Hardness, Properties, and Applications of SKD 11
Hardness
After heat treatment, SKD 11 steel can achieve a high working hardness, typically in the range of 58-62 HRC. This hardness is critical for its performance in cutting and forming applications.
Properties
- Exceptional Wear Resistance: This is its most well-known property. The high volume of carbides makes it highly resistant to abrasive wear, extending the life of tools.
- Good Dimensional Stability: It is an air-hardening steel, meaning it can be hardened with a controlled cooling process, which significantly reduces the risk of warping or cracking.
- High Compressive Strength: It can withstand heavy compressive loads without deforming, making it ideal for stamping and forming dies.
Applications
SKD 11 tool steel is extensively used in cold work tooling for cutting, blanking, forming, and stamping. Key applications include:
- Blanking and Stamping Dies
- Shear Blades for cutting sheet metal
- Fine Blanking Dies
- Woodworking Tools and Slitting Cutters
- Punches and Forming Rolls

SKD 11 Steel FAQ Section
Q1: What is SKD 11 steel used for?
A: SKD 11 steel is primarily used for cold work tooling that requires exceptional wear resistance and dimensional stability, such as blanking dies, shear blades, and forming rolls.
Q2: Can SKD 11 steel be used for high-temperature applications?
A: No, SKD 11 is a cold work tool steel and is not designed to retain hardness at elevated temperatures. For hot work applications, a specific hot work steel would be required.
Q3: Is SKD 11 easy to machine?
A: SKD 11 steel can be challenging to machine in its hardened state due to its high hardness and wear resistance. However, it can be easily machined in its annealed condition.
