Applications
Practical application cases
ER309:
Chemical plant reactor: welding 316L stainless steel lining and carbon steel shell, resistant to concentrated sulfuric acid corrosion.
Automobile exhaust pipe: connecting 304 stainless steel pipe and carbon steel bracket, resistant to high temperature oxidation.
ER309L:
Semiconductor cavity: precision welding of ultra-thin stainless steel (such as 304L) and titanium alloy.
Marine instrument: corrosion-resistant connection of underwater sensor housing (304 stainless steel and carbon steel base).
Selection recommendations
Situations where ER309L is preferred:
Long-term resistance to intergranular corrosion (such as chloride ion environment) is required.
Welding ultra-thin plates (<1.5mm) or precision equipment.
Situations where ER309 is preferred:
High-temperature and highly oxidizing media (such as molten salt furnace lining).
Thick plate welding with higher deposition efficiency is required.
