It is a nickel alloy impact steel with high toughness. It is used for cutting and
forming thick sheets due to its excellent toughness. Its hardenability and
polishability are also high. The hardness of use is between 52 – 54 Rc.
It is a nickel alloy impact steel with high toughness.
It is used for cutting and forming thick sheets due to its excellent toughness.
It is an impact steel that can be used in knives, punches, plastic injection molds
that need high hardness, mint molds, cutlery patterning molds. Its hardenability
and polishability are also high. The hardness of use is between 52 – 54 Rc.
WP7V is recommended for impact dies where higher hardness is required.
