Never induce vomiting or give anything by mouth to an unconscious person. INHALATION: Remove to fresh air, keep warm and quiet, give oxygen if breathing is difficult. Subsequent operations such as grinding, melting or welding may produce potentially hazardous dust or fumes which can be inhaled or come in contact with the skin or eyes. General Measures: Under normal handling and use, exposure to solid forms of this material present few health hazards.

Modeling and aging studies indicate that in some filler metals minor phase formation (e.g., Laves and σ) and long range order (LRO) must be assessed to ensure adequate weldability and inservice performance.īruemmer, S.M., et al. While filler metals with 21–29 wt.% grain boundary Cr show similar PWSCC resistance, the higher alloyed grades are more prone to solidification cracking. Primary water stress corrosion cracking tests show a marked decrease in crack growth rates near 21 wt. Results show that solidification segregation is critical to understanding the weldability and environmentally-assisted cracking resistance of these alloys. This paper uses experimental and computational methods to illustrate key differences among welding consumables. High alloy Ni-Cr filler metals are prone to several types of welding defects and new alloys are emerging for commercial use. Wrought Alloy 690 is well established for corrosion resistant nuclear applications but development continues to improve the weldability of a filler metal that retains the corrosion resistance and phase stability of the base metal.
