UNS S34700 stainless steel HEXAGONAL bar 

  347 stainless steel is a columbium/tantalum stabilized austenitic stainless steel. Similar to 321 stainless, it has good intergranular-corrosion resistance compared to typical 18-8 type alloys.

 347 is resistant to atmospheric conditions and should be considered for applications requiring intermittent heating between the temperatures of 800f (427c) and 1650f (899c)

Heat TreatmentAnnealing:Heat to 1850/2000 F (1010/1093c) and quench in water. Brinell hardness approximately 150.Hardening:Cannot be hardened by heat treatment, it can only be hardened through cold working.Stabilizing:If temperature during use is expected up to 1600 degrees, stabilizing between 1550/1650f (843/899c) can be used for optimum intergranular corrosion.Machinability:When machining 347 its chip is tough and stringy, use rigid tooling with heavy cuts to prevent work hardening.Specifications:AMS 5646 ASTM A182 ASTM A276 ASTM A314 ASTM A473 QQS 763 ASME SA182 EN10204 DIN3.1BShapes Manufactured:Flat Bars, Square Bars, Round Bars, Rings, Hollows, Discs, Blocks and special Shapes.
