HEAT TREATMENT OF TOOL STEEL - UddeholmHEAT TREATMENT OF TOOL STEEL 3 CONTENTS What is tool steel? 4 Hardening and tempering 4 When the steel is hardened, the matrix is not completely converted into martensite. There is always some high speed steel, the holding time will be shorter when the hardening tem-perature is
M42 can be heat treated to the highest hardness available in high-speed steel. M42 is supplied in a hardness range of 67 69 HRC. This grade can be ground nearly as easily as M2 and is the best choice for machining stainless steels, super alloys, or other high strength heat-treated materials.
Laser treatment of powder high-speed steels with prior Laser treatment of powder steels R0M6F3-MP, R6M5-MP, and R6M5-P preliminarily subjected to vacuum quenching or vacuum cyanidation with quenching promotes the formation of surface layers having an elevated wear resistance under contact-abrasive action, for example, in machining ceramic and refractory heat-resistant materials or under the surface action of ion-plasma jets of a high specific

This grade can be ground nearly as easily as M2 and is the best choice for machining stainless steels, super alloys, or other high strength heat-treated materials.
Vacuum hardening - tempering - MiheuDuring vacuum hardening, material is heated in the absence of oxygen by convection in the medium of inert gas (N) and / or heat radiation in the underpressure.Steel is hardened with a stream of nitrogen, whereby cooling rate can be determined by selecting the excess pressure. Depending on the workpiece shape it is possible also to choose the direction and time of nitrogen blowing.
Pre heat steel slowly and uniformly to 450°-500°C and equalise. Then increase more quickly to the forging temperature of 950°-1100°C and equalise prior to forging. Do not allow the forging temperature to drop below 950°C, if this occurs re heating will be necessary. Always cool the steel very slowly after forging. 5) Heat treatment. Annealing
