Description

ATI 219™ alloy, also known by the more familiar 21-6-9 or XM-11 designations* is a nitrogen-bearing austenitic stainless steel that has substantially higher strength than standard austenitic stainless steels. The alloy remains non-magnetic even after substantial cold forming and exposure to subzero temperatures. Many of the applications for the ATI 219™ alloy make use of the combination of high strength and nonmagnetic properties of the alloy, even at very low temperatures. The ATI 219™ alloy has good general corrosion resistance comparable to that of the familiar Type 304 stainless steel. The ATI 219™ alloy is produced to a lower carbon level and is more resistant to intergranular corrosion in the welded condition than higher carbon content alloys. Weldability of the ATI 219™ alloy is very good. The alloy may be welded by all the standard methods used for stainless steels. Welding procedures should be designed to retain the nitrogen level of the alloy within the weld-fusion zone. PRODUCT FORMS The ATI 219™ alloy is provided in plate, sheet and strip. All material is furnished in the solution heat treated condition
