Description

Stainless hot-work steel with heat treatment
Used for production of mould components for high volume injection moulding; can also be used for stainless functional components with high loads. Tool inserts with conformal cooling for the production of medical or chirurgical instruments as well as for packaging used in food and pharmaceutical industries. By using a special heat treatment a higher elongation can be achieved. Displays a homogeneous, dense structure.
