TECHNICAL SPECIFICATIONS: ASTM A289 18Mn-18Cr & 18Mn18Cr & 18Cr-18Mn
MATERIAL CATEGORY: 18Mn-18Cr Austenitic steel, nonmagnetic alloy
Features - ASTM A289/A289M 18Mn-18Cr
Non-magnetic stainless steel reduces the losses in the ring that are caused by eddy currents and thermal stresses. The ring is cold formed to provide the highest yield strength and to ensure plastic deformation does not occur during operation.
