SKD11 is a general cold work die steel with high wear resistance and toughness, high carbon and high chromium alloy tool steel and vacuum degassed refined steel. The steel is pure, has good hardenability and good hardenability with small quenching deformation. The steel has been softened by spheroidizing annealing, and has good machinability, fine and uniform carbide particles, and there is no need to worry about the special addition of molybdenum and vanadium, which are strengthening elements of quenching and cracking.

chemical composition:

C carbon 1.4 ~ 1.6 Si silicon ≤ 0.40 Mn manganese ≤ 0.60 P phosphorus ≤ 0.030

S sulfur ≤ 0.030 Cr chromium 11.0-13.0 Mo molybdenum 0.80-1.20 Ni nickel ≤ 0.50

V Vanadium 0.20-0.50 Cu Copper≤0.25

Features:

(1) Vacuum degassing and refining are carried out, so the internal quality is extremely clean.

(2) Good machinability.

(3) The hardenability is good, and it can be hardened by air cooling, so there is no need to worry about quenching cracks.

(4) The heat treatment deformation is very small, and the quenching deviation is extremely small, which is most suitable for molds with precision requirements.

(5) It has excellent wear resistance and is most suitable for blanking dies for stainless steel or high-hard materials.

(6) Good toughness.

Uses: 1. Used to make plastic molds, scissors, circular saws, metal stamping dies, forming rolls

2. Make cold work or hot work trimming dies, roller edges, silk patterns, wire dies, transformer core punching dies,

Rolling knives for cutting steel skin, steel pipe forming rollers, special forming cylinders, nail head dies, etc.

3. High-efficiency blanking dies, punching dies, and embossing dies for thin steel plates with a thickness of ≤6mm

4. Various scissors, inlaid parts, thread rolling dies.

5. Slider-resistant cold heading dies, deep drawing dies, cold extrusion dies.

6. Thermosetting resin molds, general plastic molds.
