Specifications

Using methods and properties
Usage: 1.2379 is a high-carbon high-chromium alloy tool steel, heat treatment has a high hardness and wear resistance, and has high hardenability, and good dimensional stability, suitable for long-life production of high precision cold die And thermoset molding plastic mold.

Features: 1. pure steel vacuum degassing refining treatment.

                2. ball softening annealing, cutting performance is good.

                3. strengthening elements vanadium, molybdenum special to join, extremely high wear resistance

Use
Uses: 1. Sheet thickness of not more than 2MM, efficient blanking die, punch die and pressure die set.
           2. scissors, inlaid blade, woodworking blade.
           3. Thread rolling die and wear-resistant slider.
           4. Cold Heading Die, thermosetting resin molding.
           5. deep drawing forming dies, cold extrusion dies.


Edit this paragraph heat treatment specifications
Cryogenic Treatment: In order to obtain the highest hardness and dimensional stability, mold immediately after the quenching of cryogenic -70 to -80 °C, maintained for 3-4 hours, and then tempered by deep cryogenic treatment of tool or die harder than conventional heat treatment Hardness 1-3HRC. Changes in shape and size of large complex parts, the production of cryogenic treatment has the risk of cracking the mold or workpiece nitriding nitriding, the surface layer has high hardness and corrosion resistance of the hardened layer of a certain organization.
