Application of EPRI P87 in Dissimilar Austenitic-Martensitic Welded Joints of TEMPALOY A-3 and T9112 June 2019 Institute of Materials, Malaysia
Many years of research have led to the development of two grades of steel by Tenaris NKK Tubes i.e. TEMPALOY AA-1 and TEMPALOY A-3. The analysis of the weldability of the latter grade is the subject of this article. Steel TEMPALOY A-3 is austenitic steel containing 22% Cr and 15% Ni, the microstructure of which does not contain ferrite delta. The primary objective of this research was to check the welding properties of high oxidation resistant superheater steel TEMPALOY A-3 welded to simulated header stud of grade T91 using EPRI P87 filer metal. After welding and heat treatment all required non-destructive tests and mechanical examinations were done. The results obtained show very good mechanical properties of welded joint.
