Dursteel Mn
Manganese Steel
Dursteel Mn is a work-hardening, non-magnetic manganese steel.
Its non-hardened (austenitic) structure provides very high toughness.
The work-hardened (martensitic) structure, reaching up to 540 HB, provides very high abrasion resistance.
DURSTEEL Mn wear-resistant steel, featuring a work-hardening surface layer (1 to 3 mm thick) and a ductile core, is ideal for many applications combining impact and abrasion.

Forming of Dursteel Mn:
Dursteel Mn is difficult to drill. It requires 12% cobalt tools or carbide inserts.
Feed must be sufficient to remove the work-hardened zone during each pass.
Sharpening should be checked regularly.
NB: It is possible to obtain smooth holes with a diameter equal to the plate thickness (minimum diameter 10 mm) by plasma cutting. Please consult us on this subject.

Why choose Dursteel Mn ?
Dursteel Mn offers exceptional resistance in environments where abrasion and impact occur simultaneously.
Under the effect of impacts, its surface work-hardens naturally over 1 to 3 mm and can reach up to 540 HB, while its core remains tough (≈200 HB).
This transformation, from austenite to a very hard martensitic structure, ensures a service life far superior to conventional steels in highly stressed areas.
Conversely, if mechanical stresses are too low to trigger this work-hardening, Dursteel Mn is not the ideal solution (consult us for a suitable alternative).
