Product Description

The cost-effectiveness of high speed steels is strongly dependent
on their alloy components. Strong fluctuations in the raw materials
market and resulting price variations have compelled voestalpine
BÖHLER Edelstahl to rethink the basic alloy concepts of the high
speed steels in our product portfolio. The result is the patented
BÖHLER S730 material, which is an economical alternative to the
generally applicable standard sort 1.3243 or M35 (BÖHLER S705).
Despite its economic advantage, BÖHLER S730 is fully equivalent to
the standard 1.3243 in terms of performance.
