GRIBINOX 309L E 309L-15
CLASSIFICATION
AWS/SFA 5.4 E 309L-15 ; IS: 5206 E 23.12.LB.20
DESCRIPTION
Extra low carbon, heavy coated & basic type, all position electrode which deposits a 23% Cr, 13% Ni austenitic stainless steel weld metal. The high alloy content and ferrite level enable the weld metal to tolerate dilution from mild steel, low-alloy steels without hot cracking or brittle structure. The welds are of radiographic quality.

TYPICAL APPLICATIONS
• Dissimilar welds between stainless steel and C-Mn Steel.
• Overlays on C-Mn steel or low-alloy steels and for joining 304/321 clad Plate.
• Similar Metal joints, Wrought and cast steels of 23Cr-12Ni type, ASTM 309 and C8.
• Joining Ferritic–Martensitic 410 and 430 type st. steels.
