APPLICATION
D6 steel, as a high carbon and high chromium alloy tool steel, is widely used in cold work stamping dies (such as silicon steel sheet punching dies, stretching dies), industrial cutting tools (heavy-duty shear blades, wire rolling dies), and special fields (thermosetting plastic forming dies, wear-resistant rolling rolls) due to its excellent wear resistance, high hardness, and thermal stability. D6 steel is particularly suitable for precision machining environments that require long-term maintenance of blade sharpness and dimensional accuracy. At the same time, its basic rust prevention ability also allows it to adapt to slightly humid working conditions.
D6 Steel Properties
D6 steel belongs to high carbon and high chromium alloy tool steel, specially designed for cold work molds. The core elements include a high proportion of carbon and chromium, significantly improving the hardness and wear resistance of the material. Chromium also endows it with basic corrosion resistance, adapts to slightly humid environments, and optimizes purity through processes such as electroslag remelting to reduce impurity defects. The chemical composition balance of D6 steel enables it to achieve ultra-high hardness levels after quenching while maintaining good structural stability.
D6 steel has the core advantage of extremely high wear resistance, and its wear resistance far exceeds that of ordinary tool steel, making it particularly suitable for high wear applications such as stamping or shearing. D6 steel achieves a good balance between hardness and toughness, which can resist high-frequency impact and deformation, ensuring the sharpness of cutting edges and the lifespan of components. Under high temperature conditions, D6 steel exhibits excellent thermal stability, prevents softening phenomena, and has low thermal expansion characteristics to maintain dimensional accuracy.
D6 steel has excellent hardenability and can uniformly harden to the core of large workpieces, reducing performance gradient issues; Low deformation tendency during heat treatment, supporting precision machining and polishing, reducing later maintenance costs. D6 steel is widely used in the field of cold work molds, including silicon steel sheet stamping molds, bending punches, and heavy-duty shearing tools, as well as wear-resistant rollers and thermosetting plastic molding molds. The comprehensive performance of D6 steel meets the requirements of high reliability and long service life in industrial scenarios.
