Bracket
After some reasearch,, the oven was set at the low end of the annealing .680 degrees The bracket was on top so maybe it did not get so hot cause the water spray to adjust temp and ash is at the top.. My guess... I did speak to a shop in jacksonville they do tempering.. He was very helpful on at what temp to bring the metal.. He said 960 once at 960 then quench in boing water. The bring back up to 360 for ten hours.. That should bring back to t6... If you skip the las t part of reheating.. Then it will be t4 .. If i brought bracket to anneall.. Or 0 then the strength is 18000 psi verse 47000 psi.tensile.... And shear is at no greater then8000psi verses25000
Elongation to failure at 15 percent... So i basiclly cut the strength to 1/3... The guy said he could try to temper it at a cost of 600... But cant gurantee that it will look like a bracket when done...
I am goin to go with the later and see what happends..
dave do you know what kind of forces are put on theses brackets?
