Significant reduction in creep life of P91 steam pipe elbow caused by an aberrant microstructure after short-term service [PDF]

Scientific Reports
P91 steel is an important steam pipe for ultra-supercritical power plants due to its excellent creep strength, which generally has a design life of 100,000 h.

Measuring Dilution and Wear for Laser Cladding of Stellite 6 Produced on a P91 Steel Substrate using Two Different Heat Inputs

MATEC Web of Conferences, 2016
Stellite 6 was deposited by laser cladding on a P91 substrate with energy inputs of 1 kW (P91-1) and 1.8 kW (P91–1.8). The chemical compositions, microstructures and surface roughnesses of these coatings were characterized by atomic absorption ...
