| Abstract: | The new-style of SKD61 steel is a medium alloy hot-mold steel. The appropriate heat treatment technology is given for new shape material of mould steel, that is SKD61, by studying the relation of the heat treatment technology and hardness. The result shows that the appropriate heat treatment technology is that the temperature for quenching is 1 025~1 070 ℃, the temperature for once is 560 ℃ and the temperature for twice is 580 ℃. Using the above quench treatment,SKD61 steel has fine martensite organization and high hardness as well as good synthesis mechanical capability. The result shows that the SKD61 steel can be used to make the complex and big size die. |
