martensitic high carbon stainless steel bars grade KS440, ACD34, DIN X65Cr13
KS440/ACD34/X65Cr13 grade stainless steel with a lower carbon content is used by EZO Japan and has greater
corrosion resistance, greater load capacity (approx 10 percent less than chrome steel) and superior low noise qualities
to the standard AISI440C grade.
The corrosion resistance of stainless steel can be increased by passivation (see section below).
400 grade stainless steel will also withstand higher temperatures than chrome steel, coping with up to 250C constant and
up to 300C intermittent with reduced load capacity. Above 300C, bearing life can be considerably shortened.
