To evaluate the properties of heat-treated SPK tool steel produced in Iran, some ingots were casted and forged with the available facilities and compared to the foriegn SPK steel. Tensile, impact and fatigue properties in full anealed and quench- tempered conditions, of these two steels were investigated.
The results show that all the properties of foriegn steel is higher than local product and it is necessary to provide advanced casting and forging facilities.
