Hardened Tool Steel W.-Nr. 1.2003 – 75Cr1 – AISI 1075
Composition: C: 0,70-0,80%, Si: 0,25-0,50%, Mn: 0,60-0,80%, P: max. 0,03%, S:
max. 0,03%, Cr: 0,30-0,40% Condition: hardened and tempered, unpolished.
Flatness max. 0.2% of the strip width, cut edges.
A small amount of Chromium leads to a higher wear resistance and better hardening
for large widths. This alloy is also suitable for small tools due to a Rockwell hardness
of 47-51 HRC.
