Gecontroleerde Leverancier General Information:
This steel grade was developed to complement standard mold steel to eliminate problems such as hardness drop-off towards the middle of the mold, maching problem and inadequate etch-grainability with large sizes of more than 400mm in cross section. A significant step taken towards dealing with these problems is to increase hardenability by alloying approximately 1% nickel.
Application:
It features excellent hardening penetration, good workability, polishing and photoengraving properties. This steel is used for plastic moulds of medium and big size. It can be subject to a nitriding treatment to improve it's wear resistance. Injection and thermoplastic extrusion moulds, rubber moulds, mould carrier frames, containers.
