Studs machined from heat-treated bar can be certified on the tests made on that bar (ASTM A962, which A193, A194 and A320 call up), and A193 waives the stud tension test for studs made from A193 bar already tested, unless they are heat treated again. Both hold only if every piece is known to come from that heat and lot.
A circular saw suits repeat lengths of bar: a short cycle and a square, clean face. Band saws take the larger sections and bundles. Either way the cut list, the heat and the job stay together in our shop.

model dataThe saw is generic: an automatic high-speed circular saw with a carbide-tipped disc on a head that slides across the bar, a wire chip brush and an oil-mist nozzle on the disc, a bar magazine, a feed vise and a main vise split either side of the blade line and an inclined grated discharge chute, drawn without any maker's features. The 2 in. bar and the heat number H-24A117 are examples; no lengths, speeds, feeds or cycle times are shown. The disc is drawn turning far slower than it runs and the close-up is slowed further; the repeats are time-lapsed. Blade and saw facts from saw-trade and patent sources (PROCESS-MACHINING-FACTS.md, circular sawing); heat traceability from ASTM A962 and A484.
