H13 Alloy Steel For Shrink Fit tool Holder

H13 steel is the most widely used and most distinctive hot work die steel. Its main characteristics are:
(1) It has high hardenability and high compensation;
(2) Excellent thermal crack resistance, water cooling can be added in the workplace;
(3) It has medium abrasion resistance, and can also use infiltration carbon or nitriding process to increase its surface hardness, but it should slightly reduce the thermal crack resistance;
(4) Due to its reduced carbon content, the secondary hardening ability during tempering is poor;
(5) It can resist softening at higher temperatures, but the hardness drops rapidly when the use temperature is higher than 540°C (1000°F) (that is, the working temperature is 540°C);
