BLUME® ER347 Datasheet

Q: How does BLUME® ER347 differ from ER316L?
A: ER347 is niobium-stabilized for enhanced intergranular corrosion resistance at elevated temperatures, making it ideal for high-heat applications, whereas ER316L is primarily used for chloride resistance in chemical or marine environments.

Q: Can BLUME® ER347 be used for welding 304 or 321 stainless steel?
A: Yes, it’s suitable for welding 304, 321, and other austenitic stainless steels, providing enhanced high-temperature stability.

Q: What shielding gas is recommended for ER347 MIG welding?
A: Use 98% Argon + 2% Oxygen or 95–98% Argon + 2–5% CO₂ for smooth, consistent arc performance.

Q: Is post-weld heat treatment required?
A: Typically no, but controlled cooling is recommended for critical high-temperature applications to maintain optimal strength and corrosion resistance.

Q: Why choose BLUME® ER347 over other brands?
A: BLUME® ER347 delivers precision-engineered chemistry, smooth arc performance, and reliable weld quality, ensuring professional-grade results and minimal rework in demanding high-temperature applications.
