We have a tubular structure made from 0.050" wall 1.5" diameter 17/7 tubing that is 14 ft long x 2 ft x 2 ft that requires heat treat to TH1050. We have determined vacuum heat treat is not necessary and our customer is now thinking that the full UTS and YS is not a necessity. Part of the expense...

We have a 17/7 PH rather complex structure of 0.050" 1.5" diameter tubes that is being welded together with 17/7 filler. To get the full strength after weld we plan on solution treating at 1900 Deg F, and then Austenitize at 1400 Deg F and then Harden at 1050 Deg F (TH1050). The structure is 15...

Thank you for your responses. Thanks to your input, we decided to purchase the 17/7 filler rods and sample weld, heat treat and tension test another round of coupons. The base metal is 0.050" 17/7 PH Cond A. We welded 8 coupons (two pieces 0.050" x 1.00" x 4.00" with a 1" overlap between with a...

We have a project that requires welding together .050" wall 17/7 PH 2" OD tubing. The tubing is structural only and welds together at an angle (TYK configurations) with fillet welds. The filler metal selected is 630 (17/4 PH chemistry). I had .050" strips of 17/7 PH welded with the 630 filler...
