Ferro Manganese or Pure Manganese?
Ferro Manganese or Pure Manganese?
(OP)
Has any one done any studies or know references pointing to which form of manganese is more effective in de-oxidation of steel melts? (ferro Manganese or pure electrolytic manganese)

You make an excellent point!
Its funny how we overlook the obvious and focus on complicated scenarios when problem solving.
I will post my findings.
I appreciate your input.

Lower carbon or no carbon grades will obviously pose problems. You need to consider,other strong deoxidisers and perhaps inert gas purging in the melt to reduce your gas porosity.
Lower carbon steel grades 1006-1012 typically use medium carbon ferro manganese. At least they did at the two mills I worked at. LC manganese was too expensive, especially compared against the cost of FeSi and Al. And typically most steel mills do not use the Mn as the de-ox agent. It's efficiency is too low compared with Si and Al.
RE: Ferro Manganese or Pure Manganese?
good point, agree. I know med carbon ferro manganese is used for low carbon grades having 0.06% and above. I had stainless steels(<0.03%C),alloy 20,hastealloys, and high Ni alloys on my mind,.
In these alloys,you need to go beyond FeSi and Al additions and cost of deoxidiser is not important

The alloys I am most concerned with are stainless steels such as CA6NM, 304, 316, CD4MCu etc and their respective L grades. That is the reason why we switched to Pure manganese.
