Technical Equipment

1) the steel can be used for silicon steel cold punching die, for dynamic loading conditions require high wear resistance, simple shapes of deep drawing and blanking die

2) is widely used to make complex shape, subjected to impact, high wear resistance requirements cold work mould, such as silicon steel cold punching die, screw thread rolling die, pull the carp module, etc.

3) used for making deep drawing die of wear-resisting of concave touch, suggest HRC hardness 62 ~ 62.

4) used for aluminum cold extrusion die punch, suggested that hardness 60 ~ 62 HRC.

5) used in the production of bending die for ⾼ wear-resisting, complex shape of convex die, die, set pieces, making punch, concave die when he suggested hardness 60 ~ 64 HRC.

6) is used for forming the carbon mass fraction is 0.5% ~ 0.80% of the elastic steel plate, in 37 ~ 42 HRC hardness, service life can reach 220000 times

7) used to make cold heading boxcar bolt die, parts size for Ф 8. 9 mm x 9.0 mm Ф concentric cylinder, the service life of only 01000 ~ 02000 times

8) used for thermosetting plastic molding mold, high resistance to mushroom, high intensity of mould

9) used in the b + quenching + tempering wear-resisting brick forming die, compared with the original use of Q235 carbon steel mold, improve the service life of 5-6 times, technology is simple, economic benefit is remarkable

10) Cr12 steel side punch after solid chromium boron altogether, convex touch edge as l6 to about ten thousand times. Conventional quenching process is only 0. 60000 ~ 0. 80000 times, boron treatment is only 0. 70000 ~ 10000 times

11) thread rolling plate Cr12 steel vanadium compound processing, increase the service life of the mold to 1. 70000

12) Cr12 steel cold heading hex head bolt bolt hexagon mold, after vanadium compound treatment, increased the service life of mould l0 times.
