Products Description
ER385 is a MIG and TIG welding wire for ultra-low carbon stainless steel. It has excellent welding technology and its deposited metal is resistant to pitting corrosion in formic acid and acetic acid media and chloride ion corrosion, making it excellent in intergranular corrosion resistance.
Product characteristics
Corrosion resistance: resistance to stress corrosion and intergranular corrosion, excellent performance against non-oxidizing acids (such as sulfuric acid, hydrochloric acid) and chlorine-containing media (such as seawater).
Low-temperature performance: full austenitic structure, high low-temperature impact value, suitable for non-magnetic or low-temperature environments.
Low-carbon design: low carbon, sulfur and phosphorus content, reducing the risk of microcracks.

Application Areas
Industries: chemical equipment, desalination, pharmaceuticals, pulp and paper, turbine components.
For example: chemical industry
ER385 welding wire is often used for welding chemical equipment due to its excellent corrosion resistance. For example, it can be used to manufacture equipment and containers for handling sulfuric acid and chlorine-containing media, which require extremely high corrosion resistance of materials. In addition, ER385 welding wire can also connect UNS N08904 base metal with other stainless steel grades to meet the needs of specific chemical environments.
Parent material matching:
904L (UNS N08904), ASTM 316 (when no ferrite is required).
For dissimilar welding of 317L and high-alloy stainless steel.
Notes
Sensitive to thermal cracks: Heat input and interlayer temperature must be controlled (recommended ≤150°C), pulse arc process is preferred.
Safety specifications: Follow AWS A5.9 standards and OSHA 29 CFR 1910 safety guidelines.
Storage requirements: Keep in a dry environment to avoid moisture, and seal after opening to prevent oxidation.
FAQ
Q: What are the environmental performance and sustainability evaluation of ER385 stainless steel welding wire?
A: ER385 welding wire does not contain flux, which means that it reduces the use of harmful chemicals in the welding process, thereby reducing pollution to the environment. The low carbon content in the composition is only 0.025% to 0.045%, which helps to reduce carbon emissions generated during welding, thus meeting the requirements of low-carbon development. The corrosion resistance of the wire enables it to maintain good performance in harsh environments, reducing material waste and secondary processing requirements caused by corrosion, further demonstrating its sustainability.
Q: How to correctly select and use ER385 stainless steel welding wire to ensure welding quality?
A: The correct selection and use of ER385 stainless steel welding wire requires a combination of its chemical composition, mechanical properties and specific welding process parameters, and adjustment according to the actual application scenario.
Q: What are the application cases of stainless steel welding wire ER385 in different industries?
A: ER385 stainless steel welding wire (904L) has a wide range of applications in different industries. Its main features include corrosion resistance, low carbon properties and suitability for a variety of welding processes.
