Hyundai S-308L.17 E308L-17 Stainless Steel Welding Electrode
The Hyundai S-308L.17 is a low-carbon austenitic stainless steel stick electrode for welding 18%Cr-8%Ni grades such as 304 and 304L. It is classified as AWS A5.4 / ASME SFA-5.4 E308L-17, JIS Z 3221 ES308L-17 and EN ISO 3581-A E 19 9 L R. Hyundai Welding lists good resistance to corrosion and oxidising environments, easy slag removal, a good bead appearance and high moisture resistance thanks to its “17” type coating. The datasheet shows ABS approval. Seven Star LLC supplies the Hyundai S-308L.17 to fabricators and maintenance teams in Oman and the GCC, and the official datasheet can be downloaded from this page.
About the Hyundai S-308L.17
Type 304 and 304L stainless steels are the most widely used corrosion-resistant alloys in industry, found in food and beverage plants, water treatment, pharmaceutical equipment, architectural work, tanks and general process piping. The E308L classification is the standard matching filler for these grades. Its low carbon content, typically 0.03% in this product, limits chromium carbide formation in the weld and so reduces the risk of intergranular corrosion after welding.
The “-17” designation refers to a rutile-acid coating with more silica than the “-16” type. In general terms, this gives a spray-like arc, a flatter, smoother bead and a slag that peels easily, which many welders favour for fillet welds and cosmetic finishes. Hyundai also highlights the high moisture resistance of the coating, which is helpful in humid coastal climates like Muscat and Sohar.

Chemical Composition of All-Weld Metal (typical, wt%)
| C | Si | Mn | P | S | Cu | Ni | Cr | Mo |
|---|---|---|---|---|---|---|---|---|
| 0.03 | 0.51 | 0.6 | 0.026 | 0.017 | 0.03 | 9.9 | 18.7 | 0.04 |
Mechanical Properties of All-Weld Metal (typical)
| Property | Value |
|---|---|
| Tensile strength | 570 MPa (83 ksi) |
| Elongation | 50% |
| Impact toughness at -60 °C (-75 °F) | 50 J (37 ft-lbs) |
| Impact toughness at -196 °C (-320 °F) | 26 J (19 ft-lbs) |
For the Hyundai S-308L.17, the high elongation of 50% reflects the ductility of the austenitic deposit, while the reported toughness at -196 °C shows that the weld metal keeps useful impact values at cryogenic temperature. Project requirements must still be confirmed by procedure qualification testing.
Diameters, Current Ranges and Packing
| Diameter | Length | Flat / horizontal fillet (A) | Vertical-up / overhead (A) |
|---|---|---|---|
| 2.0 mm (5/64 in) | 300 mm (12 in) | 25 to 55 | 20 to 50 |
| 2.6 mm (3/32 in) | 300 mm (12 in) | 50 to 85 | 45 to 80 |
| 3.2 mm (1/8 in) | 350 mm (14 in) | 70 to 115 | 65 to 110 |
| 4.0 mm (5/32 in) | 350 mm (14 in) | 95 to 145 | 85 to 135 |
| 5.0 mm (3/16 in) | 350 mm (14 in) | 135 to 180 | not listed |

Typical Uses in Oman
The Hyundai S-308L.17 is a general-purpose stainless electrode for many sectors of the Omani economy:
- Food processing, dairy and beverage plant fabrication and maintenance.
- Potable water, wastewater and desalination product-water piping in 304L.
- Stainless tanks, hoppers, handrails and architectural features.
- Instrument stands, cable tray supports and small-bore piping in oil and gas facilities.
- Cryogenic piping in 304L, where the datasheet toughness at -196 °C is relevant.
- General plant maintenance where a single electrode covers most 304-type repairs.
Welding Tips for Austenitic Stainless Steel
The points below are general welding knowledge rather than manufacturer data. Austenitic stainless steel does not normally need preheat, but interpass temperature is usually kept low to protect corrosion resistance and reduce distortion, since stainless steel has higher thermal expansion and lower thermal conductivity than carbon steel. Use stainless-only brushes, grinding discs and clamps so that iron contamination does not cause rust staining. Hold a short arc and avoid excessive weaving. After welding, heat tint can be removed by pickling or mechanical cleaning to restore the passive layer, especially on equipment for food or water service. Keep the Hyundai S-308L.17 in its packaging and redry it at 350 °C for 1 hour if it has absorbed moisture.
Why Fabricators Choose the Hyundai S-308L.17
Ease of use is the main reason the Hyundai S-308L.17 suits busy workshops. The 17-type coating restrikes readily, gives a smooth arc on either AC or DC+, and leaves a slag that lifts away with little chipping, which saves cleaning time on fillet welds and visible joints. Because it runs on AC, the Hyundai S-308L.17 can be used with simple transformer machines on remote sites as well as with modern inverters in the shop. Five diameters from 2.0 to 5.0 mm allow welders to move from thin sheet and small-bore pipe to heavier plate without changing product. The ABS approval printed on the datasheet supports use in marine and offshore work where class approval is requested. For maintenance stores in Oman that need one dependable electrode for 304 and 304L repairs, the Hyundai S-308L.17 is a practical, well-documented choice backed by the manufacturer datasheet attached to this page.
Comparing 308L and 309L Electrodes
As general guidance, 308L electrodes are the standard choice for joining 304 and 304L to themselves. When stainless steel must be joined to carbon or low alloy steel, a more highly alloyed 309L electrode is normally preferred because it tolerates dilution from the ferritic side. For 316L, a 316L electrode with molybdenum is the matching option. Choosing the Hyundai S-308L.17 for like-to-like 304L joints keeps costs down while matching the base metal chemistry.
