AWS ER308L SAW wire
Submerged arc welding wire ER308L
Submerged arc welding wire,AWS ER308L, MH0Cr21Ni10 is ultra-low carbon 18Cr-8Ni. Using with Stainless steel alkaline flux SJ601, the deposited metal has good mechanical properties. Good intergranular corrosion resistance, anti cracking performance. Corrosion resistance is more excellent because it contains low carbon.
Submerged arc welding wire ER308L
Application
Submerged arc welding wire AWS ER308L can be widely used in petrochemical and other industries. Like 022Cr19Ni10 (SUS 304L) and other materials of welding.

Welding Positions:
Notes:
1. Recommendation temperature on welding bead around 150℃.
2. Operator should strictly follow with operation specification. Amps and speed of welding should be maintained in order to avoid metal deformation by overheating.
3. 2 hour drying process is required (300-350℃) before use.
The above suggestions are for reference purpose. Evaluate and determine the situation of the scene before starting the wielding process.
