1. DC due to the temperature is not right, the hardness of 53 heat treatment should be controlled at 500 otherwise the hardness is insufficient, the hardness value of DC53 changes little when tempered at 100 500, the hardness value is slightly higher when tempered at medium temperature at 400, and the hardness peak after standard heat treatment tempering is generally about 520, after tempering at 600 high temperature.
2. I'll help you solve this problem The low hardness of DC53 heat treatment is because the temperature is wrong, and the heat treatment temperature should be controlled at about 500, otherwise the hardness is insufficient.
3. In a corrosive environment, the properties of plastic DC53 will change, such as hardness, toughness, strength, etc. The properties of the material itself have a decisive influence on the toughness, and the chemical composition, grain size, and inclusion content of DC53 will all affect its toughness.
4. There is no essential difference in the anti-rust and corrosion resistance of the two steel grades, and in order to improve the anti-rust and corrosion resistance, you can consider quenching and tempering for nitriding or N-C co-infiltration treatment. The heat treatment process of SKD11 for DC53 material increases the grain size, the residual austenite volume increases, and the performance will be reduced, but it will not be scrapped.
5. The general factory hardness of DC53 is annealed HB255, DC53 quenching heating temperature, 960 980, 520 The hardness is about 62HRC after tempering twice, and the DC53 material is made with SKD11 heat treatment process.
6. The hardness of DC53 after heat treatment is higher than that of SKD1, and it can reach 62-63HRC after high temperature tempering. DC53 is a new type of cold work die steel improved on the basis of SKD11, which overcomes the weakness of SKD11 in terms of hardness and toughness of high-temperature tempering. The hardness of DC53 after heat treatment is higher than that of SKD1, and it can reach 62-63HRC after high temperature tempering.
1. DC53 heat treatment hardness can reach 62 63HRC. DC53 is a new type of cold work die steel improved by SKD11 by Daido Special Steel, and its technical specifications are contained in the Japanese Industrial Standard (JIS) G4404.
2. DC53 heat treatment hardness can reach 62-63HRC. DC53 is a new type of cold work die steel improved by SKD11 by Daido Special Steel, and its technical specifications are contained in the Japanese Industrial Standard (JIS) G4404.
3. DC53 heat treatment hardness can reach 62-63HRC, the definition of annealing treatment, heating metal parts to a certain high temperature, maintaining them for a period of time, and then letting them cool naturally A metal heat treatment process, phosphorus p,007.
4. The heat treatment hardness of DC53 die steel is greater than SKD11, and the hardness after high temperature tempering is 62 bars and 63HRC high hardness, which is a kind of die steel with high strength and excellent toughness, with medium carbon content, under the normal heat treatment standard, the remaining austenite can be fully decomposed, and the cryogenic treatment can be omitted normally, and it can still maintain good toughness under high hardness.
5. Abrasion resistance is one of the important factors affecting the service life of DC53, under normal circumstances, the better the wear resistance of DC53, the longer the service life. The hardness of DC53 is 262HRC 362HRC, and the hardness after heat treatment can reach 561HRC.
6. How much is the toughest DC53 hardness, and what is the DC53 hardness, many people still don't know, today Fei Fei will answer the above questions for you, now let's take a look! After heat treatment, quenching and other treatments in Hengtongxing, the hardness can reach 59-60.
