H11 is a kind of high-performance die steel with excellent wear resistance and high hardness, which is widely used in manufacturing Injection mold construction and extrusion mold.
H11 is a steel material that has undergone pre hardening treatment, with a surface hardness of 290-330HBS in the pre hardening state. H11 mold steel has a high purity, not only excellent balance, polishing and etching performance, but also high hardenability and good polishing performance. Increasing carbon content can improve the hardness and wear resistance of H11, but it will reduce toughness and impact resistance, as well as reduce the strength and ductility of H11.
The chemical composition of H11 also affects its wear resistance, for example, H11 containing elements such as carbon, chromium, molybdenum, cobalt, etc. usually has good wear resistance. H11 is also suitable for precision mold processing, as its excellent resistance to temptation greatly reduces the maintenance cost of the mold.
Wear resistance is one of the most important properties of H11, and is usually measured and evaluated using methods such as wear testing and scratch testing. The hardness of H11 ranges from 28.42HRC to 36.42HRC, and the hardness after heat treatment can reach 50.41HRC.
In summary, the usage conditions should be controlled based on the characteristics and application scenarios of H11 to avoid extreme usage conditions such as high temperature, high pressure, high speed, high frequency, etc. H11 has been pre hardened to a hardness of 31-36HRC before leaving the factory through a special production process, which can reduce the heat treatment process in some projects and improve economic benefits.
