ROC Mn

Water over quenched

ROC Mn contains 11 - 14 % Manganese, over quenched, fully austenitic and then is non-magnetic, work hardening steel with an exceptionally high level of wear resistance when subjected to impact or high pressure in service.

Processing information

Cutting

Only with plasma or laser.

Forming

Cold bending and rolling are easy to perform (at workshop temperature >10 °C). It is not recommended to form in any area, hardened due to shearing operation (grinding requested).

Drilling

Please contact us for any machining aspect.

Welding

Use stainless welding products (class AWS A5.4 E 307 or 5.4 E 3.8MO).
