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.

Re: [MW:10788] ON PLOT PIPING & OFF PLOT PIPING

By Materials & Welding
Piping systems involved for the flow lines and gathering lines from the well head isolation valve to the production facility or processing plant isolation valve are determined as OFF PLOT. ON PLOT defines piping system in the processing plant and production platform. ANSI/ASME B31.4 applies for off plot piping system. B31.4 allows the use of either API 1104 or ASME section IX (as appropriate). However, occasionally, a very small system such as piping within 500 feet of a processing plant (some client also said 400 feet) may be declared B31.3 rather than B31.4. When B31.3 is invoked, only ASME Section IX is used. before you decide which code to use for welding procedure and/or welder qualification for pipe welding, you have to know the design and construction code applicable to the system. Please read far enough into scope and diagram illustrating the application of either B31.3 and B31.4 hope this helps rgds 2011/4/21 pradip kumar sil < pradipsil@gmail.com > Dear all, ...

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...
