Ultra Low Carbon Stainless Steel Welding Electrode E308L

E308L

AWS A5.4 E308L-16

Explain:

E308LIs the ultra low carbon stainless steel electrode Cr19Ni10 titanium calcium type coating, the deposited metal carbon content is less than 0.04%, have good resistance to intergranular corrosion, good welding performance, medicine Pinai red, good strength, good anti porosity, but the ac-dc.

purpose:

Used for welding ultra low carbon 022Cr19Ni10 stainless steel structure, can also be used for 06Cr18Ni11Ti work temperature less than 300 degrees, corrosion resistant stainless steel structure, mainly used for synthetic fiber, fertilizer, oil and other equipment manufacturing.
