2. Product Parameters & Material Specification — What Does 316L Mean?
- 316L: "L" denotes “Low carbon” (≤0.03%), reducing intergranular carbide precipitation and ensuring superior corrosion resistance in chloride/humid service.
- E316L-16: American Welding Society (AWS) classification:
- E: Electrode
- 316L: Compatible with 316/316L stainless base metal
- 16: Rutile-silicate based covering for use with AC/DC
- Key alloying elements: 18% Cr, 12% Ni, 2-3% Mo. Mo ensures pitting resistance in saline/acidic/chemical atmospheres.
