The inspection of tower steel words is mainly the steel seal used as identification by the inspector, such as flaw detection steel seal, which is generally produced according to the technical requirements of the enterprise. It refers to the circular pattern, pattern, character, code roll printing steel seal, etc. These steel seals are generally made on irregular abrasive tools, which requires high technology. The concave convex combination stamping and hot stamping die are used for hot stamping copper die and concave convex combination hot stamping on various gift packages.

The neutral salt bath vanadizing process of crl2mov cold working steel can obtain carbide carburizing layer after neutral salt bath vanadizing treatment of crl2mov. First, carbon vanadium compound. The carburizing layer has uniform structure, continuity and compactness of ---, uniform thickness, compact structure, micro hardness and high wear resistance of ---, and its surface hardness, wear resistance and adhesion resistance are greatly improved. 2、 The solubility of vc in austenite is higher than that in the ferrite. With the decrease of temperature, vc precipitates from the ferrite, strengthening the alloy and refining the grain, and the compound layer shows higher hardness.
This steel can? At the thickness of the production material>; For convex, concave and insert of 3mm punching die with complex shape, the recommended hardness is 58~62hrc when making convex die and 60~64hrc when making concave die. 2) ? What are the requirements for making blanking dies? Wear resistant punch and concave die. The recommended hardness is 60~62hrc for punch and 62~64hrc for die. 3) ? Is it required in the production of drawing die? For resistant female die, the recommended hardness is 62~64hrc. 4)? Requirements in manufacturing bending die? Wear resistant, complex shape punch, die and insert. The recommended hardness is 60~64hrc when making punch, and 60~64hrc5)? In the production of aluminum cold extrusion die punch, die. The recommended hardness is 60~62hrc when making punch and 62-64hrc when making die. 6) ? It is recommended to make the male die and female die of copper cold extrusion die? The hardness is 62~64hrc.
