The article presents useful information on different indices such as hardness, yield strength, compressive strength. These indices differ according to the composition of the binder and the content of carbide phase in the carbide steels. Low alloy carbon steel, stainless chromium steel, nickel steel and stainless austenitic chrome-nickel steel were used as binders. In order to revaluate the serviceability of a sintered alloy under conditions of impact loads (e.g. in press tools which are largely used under conditions of impact loads) it is important to determine limit plastic deformation, the full work of rupture (A) and the work of plastic deformation (A sub l ). In brittle thermally strengthened alloys the difference A-A sub l is substantial which suggests that the work of elastic deformation plays an important role in the work of rupture of these alloys.
