The result of the Influences of Sub-zero treatment study of blanking die for wear on Cold work tool steel JIS grade Tool Steel by Cold SKD 11 JIS SKD 11 found that the Sub-zero's treatment outcome, competency process. Effect on Microstructure: hostel nanai residues tend to decrease and chromium carbide that are likely to increase through the cold in the plating process range temperature range-20° c. -190° c There is a strong probability and impact absorption in the range 10-58.03-HRC and 59.8 8 J, respectively. After baking the night a There are strengths and absorbs shocks in 58.56 58.06-9.2 10.2-HRC and J, respectively. Baking temperature plating through cold lower chromium carbide has resulted in increased quantities. There is a small circle, and fragmented manner on a regular basis. As a result, the work piece is increased strength value, which, after baking the night a. Chromium carbide size grow up a little bit and there was a decrease of residual stress within the job. As a result, the piece has a slightly lower hardness values and increased impact absorption. Where the appropriate conditions are a temperature-190 degrees Celsius and return the baking with the strengths and values to absorb shocks that HRC and 58.56 9.2 J, respectively.
