1. Introduction to D3 materials:
D3 is equivalent to D3 steel in ASTM A681, which has good wear resistance and is suitable for making punches and punches, cold shear knives, drill sleeves, gauges, wire drawing dies, etc., which require higher wear resistance due to less impact load.
Second, D3 material use:
D3 is suitable for making punches and punches, cold shear knives, drill sleeves, gauges, wire drawing dies, etc., which are less affected by impact loads and require higher wear-resistant.

According to May 5, 2018, the 123rd China Import and Export Fair (Canton FairThe third phase closed in Guangzhou. D3O material** is generally more than 1000 yuan.
D3O material remains in a relaxed state under normal conditions, soft and elastic, once it is violently impacted or squeezed, the molecules immediately lock each other, quickly tighten and harden to digest the external force, forming a protective layer, when the external force disappears, the material will return to its original relaxed and soft state.
It can react differently to different shock situations in nanoseconds. In fact, this is a non-Newtonian fluid.
Substances, which have a viscosity completely different from those of liquids in Newton's physical collision models, such as water and gasoline.

The hip support FF is better, and other brands of D3O material do not have much cushioning effect on impact, at most so that you do not break bones.

Summary. D3M is equivalent to CR8 steel, which is a kind of cold work die steel, and is produced by Fushun Special Steel in China. Terminals for crimp connectors are used to save wiring and man-hours.
Single-touch wiring with crimp connectors. Space savings can be achieved by the lateral extension of the terminals.
The drive rod can be installed in two directions, and the switch can be installed with a large degree of freedom.
The installation spacing is the same as that of SS subminiature micro switches.
Product Category: S series subminiature, hope mine is helpful to you.
What kind of steel is D3M.
D3M is equivalent to CR8 steel, which is a kind of cold work die steel, and is produced in Fushun Yu pants special steel in China. Terminals for crimp connectors are used to save wiring and man-hours, and one-touch wiring is realized with crimp connectors. The transverse lead of the terminal is reduced by the virtual height of the terminal ・ The drive rod has two mounting directions, and the degree of freedom of switch installation is large, and the installation distance of the ruler is the same as that of the SS ultra-miniature micro switchProduct category:
S series subminiature, hope mine is helpful to you.
Who is better than D3M material and domestic CR12MOV?
Hello dear! Glad to answer for you, the difference between CR12MOV and D2. CR12MOV and D2 both belong to high-carbon and high-chromium cold work die steels, which have good wear resistance and quenching hardness up to HRC58-61.
It is widely used in metal stamping dies. Due to the different alloy content, the performance differences are different. The main differences are as follows:
1) D2 high-temperature resistant molybdenum Mo, the content is 2-3 times higher than that of Cr12MoV. Therefore, the resistance of D2 to high temperature softening is better than that of C12MoV. At high speed, the wear resistance of D2 is better than that of CR12MOV.
Pure hail 2) D2 wear-resistant alloy vanadium V, containing 3-4 times the high stroke volume of CR12MoV. Therefore, the wear resistance of D2 is 3-6 times that of CR12MOV, and the mold life made of D2 is long. Hope mine is helpful to you.

D3 cold work tool steel is a high-carbon, high-chromium leasonitic steel imported from the United States, which has high wear resistance, hardenability, hardenability, toughness, thermal stability, compressive strength, micro-deformation and other characteristics. Authentic imported D3 is a cold work die steel with excellent comprehensive performance, good machining and thermal oxidation resistance. It has a wide range of adaptability, high wear resistance, three to four times higher than general low-alloy tool steel, and good dimensional stability after quenching.
Imported D3 material.
