GM 308L

IDENTIFICATION :ER 308L

CLASSIFICATION :AWS/SFA 5.9 ER308L BS 2901-90 308 S92 DIN 8556-86 WSGX2 CrNi199

CHARACTERISTICS :

A solid, smooth wire primarily intended for welding the low carbon, 18%Cr,10%Ni, type 304 , austenitic stainless steels. Deposited weld metal has improved resistance to general corrosion .The deposited weld metal is of radiographic quality.


TYPICAL APPLICATIONS:

Suitable for welding normal carbon 304, 304L grades and Nb or Ti stabilized steels type 347 and 321 provided service temperatures are below 400oC. Widely used for chemical process plants.
