Appropriate post weld heat treatment (PWHT) is usually obligatory when creep resistant steels are welded for thermal power plant components that operate at elevated temperatures …
We study sheets made of ferritic-martensitic P91 steel subjected to electric-arc welding and heat treatment in three different modes, namely, tempering (PWDT), normalizing with …

Abstract Modified 9Cr-1Mo (P91 or C12A) steel is considered an important high temperature creep resistant material which can maintain strength at a temperature up to 650 C. In this …
The objective of the current study was to develop SMAW electrodes to American Welding Society (AWS SFA 5.5 E9018-B9) with an Ac1 temperature above the post weld heat …
