It is an optional heat treatment, which provides an increased surface hardness.

in the case of high use such as on a car production line, or, in case of fast movement (more than 0.3 meters per second), we advise this surface treatment.

This treatment gives the material a surface hardness of about 35 HRC, a hardness equivalent to that of the ball bearings'. Resistance to wear is, thus, greatly improved. Obtained under vacuum, it penetrates the material better than salt bath treatments. In this way increased hardness is effective to a depth of almost 3 tenths of a millimeter .
