Remark:

Boron in 16MnCrB5: 0.0008-0.0050

Boron is added not for increase of hardenability but to improve the toughness of the case hardened zone.

Normal condition at delivery

Unless otherwise agreed at the time of enquiry and order, the products shall be delivered in the untreated.

Machinability

All steels are machinable in the condition of soft annealed, treated to hardness range, treated to ferrite/pearlite structure and harness range, and normalized.

Grain size

Unless otherwise agreed the steel shall show a fine grain structure with an austenitic grain size of 5 or finer.

Surface condition

All products shall have a surface finish appropriate to the manufacturing processes applied.

The removal of surface defects buy welding is only permitted with the approval of the purchaser or his representative.

Marking

The manufacturer shall mark the products or the bundles or boxes in a suitable way so that it is possible to determine the cast, the steel grade and the origin of the delivery.
