Product Description
ER309 and ER309L are austenitic stainless steel welding wires designed for welding of stainless steel and carbon steel dissimilar materials, especially suitable for scenarios with high chromium and high corrosion resistance requirements.
Core difference:
ER309L has a lower carbon content (ultra-low carbon design), significantly reducing the risk of intergranular corrosion.
Both contain high chromium (23%+), giving the weld strong oxidation and acid resistance.

Applications
ER309
Welding of dissimilar materials:
Connection of stainless steel (such as 304/309/316) and low carbon steel (Q235B, 16Mn).
Automobile exhaust system (transition welding of stainless steel pipe and carbon steel flange).
Highly corrosive environment:
Chemical storage tanks (containing sulfuric acid and hydrochloric acid media), electroplating equipment lining.
Strongly oxidizing environments such as bleaching towers in the papermaking industry.
ER309L
Precision thin plate welding:
Electronic components (such as semiconductor equipment housings), medical devices (extremely high corrosion resistance requirements).
Thin-walled structures of ships (such as decks, porthole frames).
Long-term corrosion resistance scenarios:
Offshore platform guardrails (salt spray corrosion protection).
Food processing equipment (requires acid and alkali resistant cleaning agents).
