Rolling Stainless Steel Angles Built Up by Welding Two Bars Together

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.

And that’s precisely what was executed with the collaboration of a national steel service center, a local welding and fabricating “job shop” and a large capacity rolling house. Hot off the welding wire, in groups of 3 each, 748 lb. angle sections were carted from across Chicago streets to waiting rolling machine operators. Weekend pick-ups included, the roll vendor made two timely deliveries for a job considered by a field inspector to be “a mission impossible”.
The stainless steel rings will become part of new offshore support vessels which will be fueled by liquefied natural gas (LNG) tank supports. Since the vessels will be located in the Gulf of Mexico, stainless steel was the obvious alloy of choice for a salt water climate. The “go- green” use of LNG propulsion is part of an initiative aimed at reducing the environmental impact of the vessels’ operations.
So, if a rolled steel job specifies anything from a 1 x 1 x 1/8 leg-out angle or a W44 x 290# hard-way beam section, involving a Bender/Roller vendor is essential, whether in the Gulf of Mexico or Fargo, ND.
