Learn why ER316L is used for selected chemical equipment and what medium, temperature, chloride, cleaning, and welding factors must be reviewed.
ER316L is frequently selected for chemical-processing equipment because it provides a molybdenum-bearing, low-carbon stainless weld deposit compatible with many 316-series fabrications.
Where May It Be Used?
- Process piping
- Storage vessels
- Mixers
- Tanks
- Heat exchangers
- Filters
- Pharmaceutical equipment
- Food-processing systems
Why Is Project Review Necessary?
Chemical service varies widely. Suitability depends on:
- Chemical type
- Concentration
- Temperature
- Chloride content
- Flow conditions
- Aeration
- Impurities
- Cleaning cycle
- Surface finish
What Welding Practices Matter?
Use clean stainless-dedicated tools, suitable shielding gas, controlled heat input, and appropriate post-weld cleaning or passivation.
Can ER316L Handle Every Acid?
No. It should never be promoted as universally resistant to every acid or chemical.
Dayang Welding supplies ER316L wire and recommends matching the filler to the actual base material and process environment.
