SKD11 high wear-resisting ductile general cold work die steel, high carbon high chromium alloy tool steel and vacuum degassing refined steel, steel purity, has good hardenability, quenching deformation small good hardenability.The steel after spheroidizing annealing softening, machinability is good, the carbide particles small even, do not need to worry about the quenching crack strengthening jis spheroidizing annealing MachiningWhich is the correct temperature for annealing austenitizing steel?If the austenitizing steel is cooled to a slightly lower than Ar1 temperature, its A to P, and then cold to room temperature, which can shorten the annealing time greatly. This kind of annealing method is called isothermal annealing. Heat the steel to a temperature higher than Ac3 (or Ac1).See all results for this questionWhich is the best annealing method for hypoeutectoid steel?The selection of the annealing method generally has the following principles: (1) the various steels of the hypoeutectoid structure generally select complete annealing. In order to shorten the annealing time, isothermal annealing can be used. (2) the spheroidizing annealing is generally used in hypereutectic steel.See all results for this question

AISI 52100 steel is the representative of high carbon chromium bearing steel type. And it also can be called ISO 100Cr6 steel, GB GCr15 steel. After quenching and tempering, its hardness would be high and uniform. Its wear-resistance and fatigue strength are high and with good combination properties. And also with great hot workability.See all results for this questionWhat Is Annealing (7 Types of Annealing Process) | Complete annealing. Process: Heat the steel above Ac3 20 ~ 30 , heat preservation for a period Isothermal annealing. Complete annealing takes a long time, especially when the austenitic steel is Incomplete annealing. Process: Heating the steel to Ac1~Ac3(hypoeutectic steel) or Spherification annealing. A heat treatment process for spherification of carbide in steel to obtain Diffusion annealing (uniform annealing) Process: Heat the ingots, castings or forging billets to a Stress Relief annealing. Process: Heat the steel to a certain temperature below Ac1 (generally 500 Recrystallization annealing. Recrystallization annealing is also known as intermediate annealing.

spheroidizing of carbides improves the machinability of steels. However, the annealing treatment that results in spheroidization of carbides reduces the hardness of steel to a much lower value than what is required for a prehardened mold steel. Hence, design of a suitable heatThe Inspection of Spheroidized Annealing on SCM435 Cold jis spheroidizing annealing MachiningThe wires are usually produced by drawing, followed by spheroidized annealing to achieve the necessary formability for cold forging. The majority of all spheroidizing activity is performed to improve the ductility of steel [ 1] [ 2] [ 3] for cold formability.
