24 metal Materials Commonly Used in Mold Processing and Their Characteristics (Two)
4. HT150 - gray cast iron
Application examples: gear boxes, machine tool beds, boxes, hydraulic cylinders, pump bodies, valve bodies, flywheels, cylinder heads, pulleys and bearing caps, etc.
5. 35 - Commonly used materials for various standard parts and fasteners
Main features: appropriate strength, good plasticity, high cold plasticity, and acceptable weldability. It can be partially upsetting and drawing in the cold state. Low hardenability, use after normalizing or tempering. Application examples: Suitable for manufacturing parts with small cross-sections and capable of withstanding large loads, such as crankshafts, levers, connecting rods, shackles, various standard parts and fasteners.
6. 65Mn - commonly used spring steel
Application examples: various small-sized flat and round springs, seat springs, spring springs, spring rings, valve springs, clutch reeds, brake springs, cold-rolled coil springs and circlips, etc.
7. 0Cr18Ni9 - the most commonly used stainless steel (U.S. steel number 304, Japanese steel number SUS304)
Characteristics and applications: It is most widely used as stainless heat-resistant steel, such as food equipment, general chemical equipment, etc.
8. Cr12 - commonly used cold work die steel (U.S. steel number D3, Japanese steel number SKD1)
Characteristics and applications: Cr12 steel is a widely used cold work die steel, which is a high-carbon, high-chromium ledeburite steel. This steel has good hardenability and good wear resistance; because the carbon content of Cr12 steel is as high as 2.3%, it has poor impact toughness, is prone to brittleness, and is prone to forming uneven eutectic carbides; Cr12 steel has It has good wear resistance and is mostly used to manufacture cold punching dies, punches, blanking dies, cold heading dies, cold extrusion dies, punches and dies, drill sleeves, and gauges that are subject to small impact loads and require high wear resistance. , wire drawing dies, impression dies, wire rubbing plates, deep drawing dies and cold pressing dies for powder metallurgy, etc.
9. DC53 - commonly used cold work die steel imported from Japan
Characteristics and applications: High-strength and toughness cold work die steel, steel grade manufactured by Japan's Datong Special Steel Co., Ltd. After high temperature tempering, it has high hardness, high toughness and good wire cutting properties. Used for precision cold stamping dies, drawing dies, thread rolling dies, cold blanking dies and punches, etc.
