ER316 SS TIG WIRE | FEATURES
- The nominal composition (wt,-%) of ER316 is 19 Cr, 12.5 Ni, and 2.5 Mo.
- It has been used successfully in certain applications involving special base metals for high-temperature service.
- The presence of molybdenum provides creep resistance at elevated temperatures and pitting resistance in a halide atmosphere.
- Welding process of ER316 SS TIG rod applied to TIG(Tungsten Inert Gas Welding) or GTAW(Gas Tungsten Arc Welding).
SPECIFICATION CONFORMANCES
AWS: A5.9/A5.9M: ER316
UNS Number: S31680
BS EN ISO 14343B: SS316
PACKAGING
Length: 1meter/3.05feet. Weight: 4.5kg/10lb.
TYPICAL APPLICATION
- ER316 SS TIG rod is used for welding Type 316 and similar alloys, such as 316 and 316N.
- Applied to LNG Storage, Cryogenic Vessels and Piping.
WELDING POSITIONS: F,V,OH,H
SHIELDING GAS: 100% Argon
Rapid corrosion of ER316 weld metal may occur when the following three factors co-exist:
1. The presence of a continuous or semicontinuous network of ferrite in the weld metal microstructure.
2. A composition balance of the weld metal giving a chromium-to-molybdenum ratio of less than 8.2 to 1.
3. Immersion of the weld metal in a corrosive medium. Attempts to classify the media in which accel- erated corrosion will take place by attack on the ferrite phase have not been entirely successful. Strong oxidizing and mildly reducing environments have been present where a number of corrosion failures were investigated and documented.
