The Effect of Each Elements on the Low W-Mo-V High Speed Steel

Sadao Koshiba


Abstract:

The author carried out a series of experiment on the effect of each elements, i.e. C 1.0∼1.4%, Cr 3∼6%, W 4∼1%, V1∼3%, for standard composition containcing C 1.1%, Cr 4%, W 6%, Mo 2%, V2% and studied changes in their hardness and microstructures brought about by different heat treatments, and also tested their cutting durability by putting them in actual service. As the results of this investigation, it is ascertained that moderate composition are C 1.0∼1.2%, Cr 4.0∼5.5%, W 5∼7%, Mo 2%, V 1.8∼2.8%, and that this high speed steel containing moderate composition have better cutting durability than low tungsten high speed steel containing W 11%.
