Hot work tool steels are a group of alloy tool
steels that enable ferrous and non-ferrous materials to be shaped by various
methods such as injection, |
|
|
extrusion, forging and cutting under high
temperature conditions (300-600°C). Hot work tool steels, which are used in
the high temperature forming |
|
|
|
of
metal-based raw materials, are a steel group with a significant usage area in
today’s manufacturing and mold industry. Features expected in |
|
|
|
|
in Hot Work Tool Steels; High tempering
resistance, high temperature strength, resistance to thermal shocks, good
machinability, hot wear resistance. |
