IDENTIFICATION
GRILOY 41N E410-15
CLASSIFICATION
AWS/SFA 5.4 E410-15
DESCRIPTION
A basic coated hydrogen controlled electrode manufactured using alloyed core wire designed for welding wrought or cast martens tic (12% Cr type 410) stainless steel. The weld metal contains just sufficient carbon to enable air hardening transformation to a predominantly martens tic microstructure. The electrode exhibits good erosion and abrasion resistance. It deposits weld metal of X-ray quality.
