OVERVIEW SPECIFICATIONS AND TECHNICAL INFORMATION
See Stainless Steel Tolerances
Stainless Round Bar 347 provides high strength, high temperature capability, and corrosion resistance in strongly oxidizing environments. 347 is an austenitic stainless and also can operate at high temperatures without losing strength. It is typically used in aerospace for aircraft exhausts, collector rings, expansion joints, and in high temperature chemical processing.
