Re: [MW:14131] 13% Mn steel Welding

Hi Harish

 

For welding 13-14% Mn Steels you can use Austenitic manganese steel : E18-8-6 type SMAW electrodes or FCAW wires.

This electrode contains 0.1-0.4%C, 18%Cr, 8%Ni and 6% Mn. The weld deposits are work hardenable type. As deposited hardness=200HB, after workhardening= 47 HRC.

Welding has to be done very slowly with controlled interpass temp. of 150 degrees Celcius max.

Mostly the component is immersed in a water bath tub during welding to maintain the interpass temp.

Also weld with low heat input, lower current settings. Weld stringer and short beads.

 

If you tell me the application i can give you the solution as i have welded plenty of Hadfield steels !

Dear Experts,

                     Please share some welding data on 13% Mn (Hadfield) steel. Like electrode, suppliers, welding parameters.

regards,

Harish.
