Zinc-free alloys are required as materials for fittings in electron tubes to avoid zinc vaporisation. Titanium promotes the formation of pore-free welds because it can tie up oxygen, hydrogen and nitrogen, due to its high affinity for these gases. The most harmful of the dissolved gases is oxygen, which can cause pitting of metal. Note that the O 2 solubility in water at around 60C is about 8 ppm and thus is "Sinc The fire-tube boiler developed as the third of the four major historical types of boilers: low SS316 has a higher resistance to pitting and crevice corrosion in chloride environments Grade L series has lower C (0.035%) which improves its use for higher temp up to 1100F (600C), has a higher resistance to IGC and better weldability, Better mechanical strength at elevated temps & good high temp oxidation resistance up to 925C.
