toggle design
Ahoy All ,,,, I am curious as to how the "Tee" on the tee-bolt stud toggle is formed ,,,, does anyone have a clue ?
Also has anyone put their 50 power h/h Edmund Scientific microscope on the bent over area of a SS plate toggle ? Would they notice deformation cracking at that bend and if not , "How Do They Do That" process without cracks showing up ?
My information on SS crevice corrosion comes from the paper mill industry in the PNW . Seems that the pulp bleaching SS tanks were developing pin hole leaks near the SS tank joint welds .
The research discovered the problem as a free chloride ion attacking that weld area , and causing pin hole corrosion .
Later I find out my SS water tanks onboard were suffering the same pin hole corrosion ,,, the cause determined to be bleech or chlorine in the water to sterilize that tank water , taken onboard from city water systems delivered fresh water . Ah , Ha ! so that is what ruined my onboard SS water tanks !
Now , later , thinking 2 + 2 ,,,, salt in salt water is a sodium chloride solution, with plenty of free chloride ions .
What I learned even later ,,,, was ,,,, that when you weld SS ,, the molten welding puddle boils off a portion of the nickel content ,,,, so you don't have SS 18-8 at the weld area anymore , but an alloy , something less than that 18 - 8 SS you purchased .
