Mn-alloyed steel
Mn-alloyed steel
(OP)
Does anyone know of a steel containing 6% Mn with a low carbon (0.12%) and small additions of Mo and V, without Cr or Ni?
I'm told it has superior fatigue resistance.

Corrosion never sleeps, but it can be managed.

RE: Mn-alloyed steel
We had the same tought. The carbon and manganese are to low to speak of Hadfield steel and there is no Cr nor Ni involved.
Is strain hardening beneficial for fatigue resistance?
What would be the effect of the high Mn on welding and casting?
From what we have heard this alloy is used in France in bridge building and is known there as X12MnMoV6.
RE: Mn-alloyed steel
Regarding welding, Mn is an austenite stabilizer, and as such, I would expect this material to be welded with minimum preheat in the field. This material should be readily weldable.

As workhardening occurs the TS increases so also the fatigue strength should improve.
