Överum Mucro is the name of the heat-treated steel
used in Överum wearing parts.
The raw material is chosen with great care and heat-treated
according to Överum's own method.
The correct carbon content in the steel profile determines
the properties of the mouldboard. The mouldboard blanks
are processed for 24 hours in an oven with carbon-rich
environment and pulsating temperature. Carbon then penetrates
into the surface layer of the steel. The subsequent heat-treatment
will give the surface layer both hardness and wearing resistance
at the same time as it gives toughness and impact strength in the
centre of the mouldboard.
