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.

Designed for welding and regeneration of wear parts of 12-14% Mn steels, because 
of high tensile strength and impact energy. weldments provides resistant on impact, 
wear, abrasion etc. 

The  High Mn-content produces a fully austenitic deposit. 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

Why not EFeMn/ErFeMn?

ASTM A 128 Gr. 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 or 
repairing of broken casting.

Austenitic Mn steels with 14% Mn (also known as Hadfield steels) have a tendency 
to form brittle precipitates in the form of carbides. It is essential to weld without 
preheating, 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 metal
cracks and fissures.

Heat tint (temper) colours on stainless steel surfaces heated in air // Heat tint

By Materials & Welding
Introduction The colour formed when stainless steel is heated, either in a furnace application or in the heat affected zone of welds, is dependent on several factors that are related to the oxidation resistance of the steel. The heat tint or temper colour formed is caused by the progressive thickening of the surface oxide layer and so, as temperature is increased, the colours change.   Oxidation resistance of stainless steels However, there are several factors that affect the degree of colour change and so there is no a single table of colour and temperature that represents all cases. The colours formed can only be used as an indication of the temperature to which the steel has been heated. Factors affecting the heat tint colours formed Steel composition The chromium content is the most important single factor affecting oxidation resistance. The higher the chromium, the more heat resistant the steel and so the development of the heat tint colou...

The Schaeffler and Delong diagrams for predicting ferrite levels in austenitic stainless steel welds

By Materials & Welding
Introduction Ferrite is important in avoiding hot cracking in during cooling from welding of austenitic stainless steels. 'Constitution diagrams' are used to predict ferrite levels from the composition by comparing the effects of austenite and ferrite stabilising elements. The Schaeffler and Delong diagrams are the original methods of predicting the phase balances in austenitic stainless steel welds. Nickel and chromium equivalents A 'nickel equivalent' is calculated for the austenite stabilising elements and a 'chromium equivalent' ferrite stabilising elements. These are used as the axes for the diagrams, which show the compositional equivalent areas where the phases austenite, ferrite, martensite (and mixtures of these) should be present. Although intended to show the phase balance of weld fillers, these diagrams can also be used to illustrate the phase balance of the 'parent' material. There are different diagrams for dif...
