Hello,
The question was as following:
"I am using ASTM A128 Grade B1 Material welding , Please suggest Which electrode to be use."
This was a very general question. You have to give all the details (i.e. service requirements, is it production weld or repair etc.)
If you do not know details at the moment, I recommend you to search online; there are lots of information about welding Hadfield steels and you may find what you are looking for. Even if you don't, you will have a better understanding of the problem and then you can give the group required details so that the members could help you with this particular problem.

--E Fe Mn series also has the same MN % with yield austinetic deposit anyhow crack free can be considered in your case.Thanks for your reply.

The deposit is highly work hardening and hardens during service from originally 200-250 to 450 HB.Machining is possible with tungsten carbide tool or could be ground.E 312 or E 309 produces crack free welds and are better choices compared to E Fe Mn---------------------------------------------------------------------------------------------------------------------On Thursday, 24 January, 2019, 7:56:59 AM IST, muneebslsa@gmail.com <muneebslsa@gmail.com> wrote:--Why not EFeMn/ErFeMn?

B-1 is High Manganese cast steel with 11.5 to 14 % Mn,C & Si under 1.0 %.You have not mentioned whether it is hard surfacing orrepairing of broken casting.Austenitic Mn steels with 14% Mn (also known as Hadfield steels) have a tendencyto form brittle precipitates in the form of carbides. It is essential to weld withoutpreheating, even with additional cooling and keep the specific heat input low.E 312-16 with 30 Cr & 10 Ni will be ideal It has two phase structure with substantial amount of ferrite in austenitic matrix. Weld metal is highly resistant to weld metalcracks and fissures.Sridhar.-------------------------------------------------------------------------------------------------On Monday, 21 January, 2019, 3:14:05 PM IST, ksraghavn <sanirudh2000@gmail.com> wrote:--
