## Summary description

Electrode Monolith M-309L is a set of three stainless steel welding electrodes with a 2.5 mm diameter. Designed for welding stainless steels compatible with M-309L composition, the electrodes offer consistent arc stability and suitable deposition for repair, fabrication, and maintenance tasks. Ideal for small-scale stainless steel joins and patching work, they provide reliable performance for workshop and professional use.

## Long description

Electrode Monolith M-309L stainless steel 2.5 mm, set of 3 are welding electrodes intended for joining and overlay of various stainless and carbon steels where service temperature does not exceed 300°C. The electrodes are suitable for welding austenitic stainless steels (examples: AISI 304, AISI 304L, 08Х18Н10, 03Х18Н11) and for working with heat-resistant austenitic grades such as AISI 309 and AISI 309S and similar alloys (20X23H13, 08X23H13). They are used for transition and buffer layers before applying corrosion- or heat-resistant surface deposits on chromium‑molybdenum perlitic steels and on ferritic‑perlitic or low‑ and medium‑alloy bases. The set includes three electrodes with a diameter of 2.5 mm.
Advantages
Monolith M-309L electrodes provide stable arc characteristics and predictable deposition suited to repair, fabrication and maintenance tasks. Their composition matches austenitic and heat‑resistant stainless steels, allowing controlled transition layers and reliable buffer coatings. Compact 2.5 mm diameter rods enable precision work on small joints and localized patches in workshop or professional environments.
Suitable for
Welding austenitic stainless steels (AISI 304, AISI 304L, 08Х18Н10, 03Х18Н11)
Overlay and transition layers on heat‑resistant austenitic steels (AISI 309, AISI 309S, 20X23H13, 08X23H13)
Buffer and transition coatings on chromium‑molybdenum perlitic steels
Repairs, patching and small‑scale stainless steel joins in workshops
Key specifications
Brand: Monolith
Model/MPN: 30194075
EAN: 4820130194075
Electrode type: Stainless steel welding electrode M-309L
Diameter: 2.5 mm
Quantity: 3 pieces per set
Recommended maximum service temperature: 300°C
How to use
Select appropriate welding current and polarity for 2.5 mm stainless electrodes according to your welding machine and the base metal. Clean the joint area from scale, oil and contaminants before welding. Use the electrodes to deposit transition or buffer layers when building up overlay for heat‑resistant or corrosion‑resistant surfacing, and perform finishing passes as required to achieve the desired geometry and metallurgical bond.
Usage recommendations
Store electrodes in a dry place to avoid moisture pickup. Preheat and interpass temperatures should follow the recommendations for the specific base metal and alloy; avoid service applications above 300°C unless metallurgical suitability is confirmed.
