What happens when over 47,000 lbs. of Type 304 stainless steel rolled angle segments are required rather quickly and the producing mills cannot provide these parts for more than 20 weeks? Simple: take 20ft plate x 1in. thick, saw it into 5- and 6-inch wide bars, bevel a long edge, then provide full penetration weld, thereby creating 63 lengths of 6 x 6 x 1 x 20ft angle section ready to roll and saw trimmed to 120 degree. Voila!
These angle ring segments will supply enough arc to make 21 complete rings with a 173 inch diameter.
