Blanking dies for electric home appliance components

Application: Blanking dies for Ni based alloy materials used for medium-scale production of television components.

Results:

Material Conventional D2 DC53 Dimensions (mm) Ni based alloy (0.2mm thick) 58/59 HRc Tempered 510oC 62/63 HRc Tempered 510oC 35 X 100 X 250 Evaluation 5,000 25,000 5 times

Comments: The worked material is tough and tools produced in conventional D2 were subject to chipping and seizing. High temperature tempering and high hardness are important in preventing seizing and extending the life of die edges. DC53 was able to satisfy both requirements

Flat Thread Rolling Dies

Application: Flat Thread Rolling Dies for working stainless steel bolts where there is a particularly high working load.

Results:

Comments: Tools made with conventional D2 required early grinding as the result of chipping and local seizing of threads. Working with stainless steel requires high toughness, high hardness and high resistance to temper softening. DC53 proved fully effective.

Rolls for Straightening Machines

Application: Straightening of heat-resistant steel and stainless steel where pitting of the roll is a major problem and high hardness and toughness are required.

Results:

Comments: Conventional rolls were suffering from severe pitting and local seizing resulting in very limited runs. Rolls in DC53 fully satisfied the demand for high toughness to prevent pitting and high hardness to avoid seizing.
