E316L-17 stainless steel manual arc welding electrode is an ultra-low carbon, excellent corrosion resistance basic coated welding electrode, specially designed for welding 316L and similar low alloy austenitic stainless steel. Its deposited metal contains molybdenum (Mo) and low carbon content (C≤0.03%), which significantly improves the resistance to intergranular corrosion and is suitable for welding needs in harsh environments such as chemical industry, marine engineering, and food equipment.
Core advantages
Carbon content ≤0.03%, effectively reducing carbide precipitation in the heat-affected zone of welding, avoiding intergranular corrosion, and extending the service life of equipment.
Contains molybdenum (Mo 2.8%-3.0%), chromium (Cr 18%-19%), and nickel (Ni 12%), suitable for environments resistant to sulfide, chloride and organic acid corrosion, such as petrochemical pipelines, seawater treatment equipment, etc.
Arc welding electrodes have stable arc, small spatter, easy slag removal, beautiful weld formation, suitable for all-position welding (horizontal, horizontal, vertical, overhead welding)
Deposited metal tensile strength ≥570 MPa, yield strength ≥430 MPa, elongation ≥45%, impact toughness (+20℃) ≥60 J, meeting the needs of high-strength structural welding.

User Guide
1.Preparation before welding:
- Remove oil and oxide layer from the surface of the base material and keep it dry;
- The recommended preheating temperature is ≤150℃ (thick plate or high constraint conditions).
2.Welding parameters:
- Diameter 2.5mm: current 90-110A;
- Diameter 3.2mm: current 100-130A;
- Interlayer temperature is controlled below 150℃ to avoid overheating.
3.Post-weld treatment:
- No heat treatment is required, pickling or passivation can be performed directly to enhance corrosion resistance.
Notes
Avoid using in high temperature environments above 400℃ (such as high temperature section of boiler);
Store in a dry and ventilated place. Use within 4 hours after opening or re-dry (350℃×1 hour).
FAQ
Q: Which materials are the E316L-17 electrodes suitable for welding?
A: Mainly used for welding 316L, 316 and other austenitic stainless steel, can also be used to weld the corrosion resistance requirements of similar alloy materials, widely used in chemical, food, medical equipment and other industries.
Q: What kind of treatment is required for E316L-17 electrodes before welding?
A: Welding rods should be dried at 150 - 200 ℃ for 1 - 2 hours before use, and then placed in a 100 - 150 ℃ heat preservation cylinder, as used, in order to remove the moisture in the flux skin, to prevent the weld from producing porosity and other defects.
Q: E316L-17 Is DC or AC power used for electrode welding?
A: The electrode can be used with AC or DC positive power supply. The arc is more stable and the weld quality is better when using a DC power source, which provides better control of the molten pool and weld shaping, especially when performing all-position welding.
