Hardened and tempered Stainless Tool Steel W.-Nr. 1.4034 - X46Cr13 – (AISI 420)
Composition: C: approx. 0,46%, Si: max. 1,00%, Mn: max. 1,00%, P: max. 0,04%,
S: max. 0,03%, Cr: 12,5-14,5% Condition: hardened and tempered, brush polished.
Flatness 0,20% of the strip width, cut edges.
Due to the content of 13% Chromium this steel is corrosion resistant at wet air,
steam and water, but not resistant against chloride ions and acids. The alloy 1.4034
has advantages in better wear resistance and low inner stress compared to temper
rolled stainless steels like 1.4310 (AISI 301), but a lower corrosion resistance. With
a hardness of 50-52 HRC this alloy is used for gauges, small tools and knifes.
