Ⅰ.Application
D3 tool steel is one type oil-quenched,high carbon, high chromium steel;
It is heat treatable and offer a hardness in the range of 58-64HRC;
D3 tool steel possess high resistance to wear or to abrasion and for resistance to heavy pressure;
D3 machining is limited to finished grinding due to its abrasion resistance in the hardened condition;
With its non-deforming properties, D3 is unsurpassed for die work on long production runs.
It is widely used for blanking and forming dies,forming rolls , press tools , punches, bushes.
