NAK80 mold steel is we have been optimistic about the steel, NAK80 mold steel heat treatment cracking factors, generally can be summarized into several aspects of the mold structure, mold materials and heat treatment. These factors through the role of stress in the heat treatment, prompting the cracks. To prevent cracking of the heat treatment, it is necessary to take full account of all relevant factors. 2 Features Editor ● without heat treatment, polishing of optical excellent machinability, Etched good ● pure steel vacuum degassing refining treatment. ● ball annealing softening, cutting performance is good. ● strengthening elements vanadium, molybdenum adding special, extremely excellent abrasion resistance. The chemical composition of the elements C Si Ni Mn Mo Cu AI Cr Fe content 0.15 0.3 3.0 1.5 0.3 1.0 1.0 0.3 Other uses are generally used in a mirror iron polished mold, dust, TV filter plate, cosmetics boxes, precision mold processing wrinkles, office automation equipment, automotive parts EDM die. Transparent or require finish products, such as Transparent mold articles on home, car, cameras, computers and so on. ● Sheet thickness of not more than 2MM, efficient blanking die, punch die and pressure die carrier. ● all kinds of scissors, the insert, woodworking blade. ● thread rolling die and wear-resistant slider. ● Cold Heading Die, thermosetting resin molding. ● deep drawing mold, cold extrusion dies
