Description

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.
