AISI 314 stainless steel is an austenitic stainless steel formulated for primary forming into wrought products. 314 is the AISI designation for this material. 1.4841 is the EN numeric designation. Additionally, the EN chemical designation is X15CrNiSi25-21. And the UNS number is S31400.
It has the lowest electrical conductivity relative to other wrought austenitic stainless steels in the database.
The properties of AISI 314 stainless steel include two common variations. The property values on this page show ranges across all of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare AISI 314 stainless steel to: wrought austenitic stainless steels (top), all iron alloys (middle), and the entire database (bottom).
