SKD11 tool steel is a premium-grade cold work die steel under the JIS G4404 standard, equivalent to AISI D2 and DIN 1.2379. It is characterized by high carbon (1.4–1.6%) and chromium (11–13%) content, providing exceptional wear resistance, high hardness, and good toughness. SKD11 maintains dimensional stability during heat treatment and offers outstanding performance in high-pressure, high-wear applications. It is widely used for manufacturing cold work dies, punches, cutting tools, shear blades, and wear-resistant components. Available in hot rolled, forged, and precision-ground forms, SKD11 is suitable for CNC machining and can be supplied as annealed or pre-hardened material to meet diverse manufacturing needs.

| SKD11 Alloy steel Applications: |
Cold Work Dies – Punching dies, blanking dies, forming dies, and trimming dies for sheet metal processing.
Cutting Tools – Shear blades, slitting knives, and industrial cutting knives.
Rollers and Guides – Cold rolling mill rolls, forming rollers, and guide rails.
Wear Parts – Bushings, wear plates, and precision mechanical components subjected to abrasion.
Molding Components – Injection mold inserts, compression mold parts, and stamping molds requiring high wear resistance.
Precision Engineering – Components for aerospace, automotive, and heavy machinery where tight tolerances are critical.
1.Black Surface – As-rolled or forged finish with oxide scale.
2.Ground Finish – Bright appearance with a slightly rough texture; not precision ground.
3.Machined Plate Finish – Bright and accurate dimensions; minor turning marks may be visible.
4.Peeled/Turned Finish – Bright with precise sizing; slight turning marks remain.
5.Polished Finish – Highly bright with precise dimensions; free from turning marks.
Q1: What is SKD11 tool steel equivalent to?
A1: SKD11 is equivalent to AISI D2 and DIN 1.2379 cold work tool steel.
Q2: Can SKD11 be used for high-volume stamping dies?
A2: Yes, its high wear resistance and toughness make it ideal for large production runs.
Q3: What is the typical hardness of SKD11 after heat treatment?
A3: SKD11 can reach 58–62 HRC after proper quenching and tempering.
Q4: Does SKD11 have good corrosion resistance?
A4: It has better corrosion resistance than low-alloy tool steels but less than stainless steel.
Q5: What is the main advantage of SKD11 over other cold work steels?
A5: Its combination of high hardness, wear resistance, and dimensional stability.
