TIG/MIG ER309 ER309L Stainless Steel Welding WireTIG/MIG ER309 ER309L Stainless Steel Welding Wire AWS A5.9 acid resistance

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).
