Material Notes:

Description: HBÖHLER M268 VMR is a hardened and tempered plastic mould steel with excellent cleanliness for best polishability. The hardness is constant over the entire cross-section of the steel block, even at large sizes, due to the addition of nickel.Applications: Moulds for plastics processing, components for general mechanical engineering and tool manufacture where highest polishability and fatigue strength are required.
