Welding Electrode
E316L-16 Stainless Steel Welding Electrode
E316L-16 is a low-carbon covered electrode for shielded metal arc welding (SMAW), classified under AWS A5.4. It is primarily used for welding 316L and compatible molybdenum-bearing austenitic stainless steels. Its chromium-nickel-molybdenum weld-metal composition is designed for suitable corrosive service environments. The low carbon limit helps reduce chromium carbide precipitation, while molybdenum contributes to resistance against pitting and crevice corrosion.
E316L-16 for Molybdenum-Bearing Stainless Steels
E316L-16 is a low-carbon covered electrode for shielded metal arc welding (SMAW), classified under AWS A5.4. It is primarily used for welding 316L and compatible molybdenum-bearing austenitic stainless steels.
Its chromium-nickel-molybdenum weld-metal composition is designed for suitable corrosive service environments. The low carbon limit helps reduce chromium carbide precipitation, while molybdenum contributes to resistance against pitting and crevice corrosion. Actual corrosion performance depends on the base material, weld quality, surface condition and operating environment.
Typical Applications
E316L-16 is commonly used in fabrication involving:
- Chemical processing tanks, vessels and compatible piping
- Pharmaceutical and food-processing equipment, where material compatibility is confirmed
- Heat exchangers and industrial stainless steel assemblies
- Maintenance of 316L and compatible Cr-Ni-Mo stainless steel components
The filler metal should be selected according to the specified base material and service conditions. For dissimilar stainless steel-to-carbon steel joints, an E309L-type electrode may be more appropriate, depending on the welding procedure.

Selecting the Right Electrode
E316L-16 is intended for applications requiring low-carbon, molybdenum-bearing stainless steel weld metal.
- E308L-16: Commonly selected for compatible 304L stainless steel applications.
- E316L-16: Selected for compatible 316L stainless steels where molybdenum-bearing weld metal is specified.
- E309L-16: Often considered for certain dissimilar-metal joints.
These classifications are not interchangeable in every application. Confirm the material specification and qualified welding procedure before substitution.
