GRINOX 9L E309L-16
CLASSIFICATION
AWS/SFA 5.4 : E 309L- 16, IS : E 23.12 LR 26,
BS 2926-84 23.12 LR, DIN 8556 E23.12 LR 23
DESCRIPTION
An extruded, rutile based heavy coated all position electrode which deposits extra low carbon 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 and low alloy steels without hot cracking or brittle structure.

TYPICAL APPLICATIONS
Joining of clad steels and dissimilar joints between stainless and mild or low alloy steels. Buffer layers on mild and low alloy steels prior to overlaying with E 308L electrode. Welding of similar compositions, 309 type austenitic stainless steel. Joining ferritic – martensitic stainless steel type 410 and 430.
WELDING PROCEDURE
The base metal should be free from oil, grease or dirt before welding. Keep a short arc-length. The weld bead should be cleaned with stainless steel wire brush.
REDRYING : 250°C / 2 hrs., max 5 cycles, 10 hr. total.
