WebFor P91, austenite is very stable, and it needs to be cooled to a lower temperature (about 400°C) to become martensite. The coarse martensite structure is brittle and hard, and the joint is under complex stress. At the same time, hydrogen diffuses from the weld to the near-joint zone during the cooling process of the weld. WebKeywords: CSEF, P91, welding, WPS, WPQR, WQTR, NDT, preheat, PWHT.
