G-TECH 308LB
SMAW
- AUSTENITIC STAINLESS STEELS
308L
Description
Basic coated low carbon electrode for 304L austenitic stainless steels base materials
Wire with a typical ferrite content of 0.5 FN maximum that provides a fully austenitic and non-magnetic weld deposit. The high level of Mn content ensures freedom from micro cracking and helps to stabilize the austenitic microstructure and aids in hot cracking resistance. Suitable for low temperature applications down to –269°C (e.g. LPG and LNG storage vessels) and where non-magnetic property is required. This filler metal also exhibits good corrosion resistance in acids and seawater, and is particularly suited for corrosion conditions found in urea synthesis plants.
