Steel has high strength at elevated temperatures, high hot wear resistance,
good toughness, thermal conductivity and is resistant to hot cracking.
Limited water cooling possible. Similar to AISI H13.
1.2344 (WP5V)
It is a hot work steel that does not lose its mechanical properties and
therefore wear resistance at high temperatures. It has very good thermal
stability and toughness. Limited cooling possible.
Description
APPLICATION AREAS
APPLICATION AREAS
It is a standard material in hot forming dies. It is used in areas such as
extrusion tools, forging molds, aluminum injection molds, hot cutting blades,
plastic molds. Since it has high impact resistance, it can also be used in thick
sheet metal cutting dies when necessary.
