Morphology of Inclusions and Its Refinement Mechanism in the New P91 Heat-Resistant Pipeline Steel
A new type of P91 heat-resistant pipeline steel ingot was prepared by feeding Al twisted wire into a steel melt through a multi-point regional micro-supply method, combined with electromagnetic stirring. The type, shape, and size of inclusions in the new

Effect of Grit Blasting and Thermal Spraying on Microstructure Evolution of P91 Weldment [PDF]
In the present work, studies have been carried out on the variations in the microstructure and hardness of P91 base-metal and welded joint. This variations result from the grit blasting and thermal cycle experienced during the thermal spraying process ...

Creep Rate, Friction, and Wear of Two Heat-Affected Zone Regions of 9–12 wt.% Cr Steels
Coarsening of precipitates can have a profound effect on the mechanical properties of martensitic 9–12 wt.% Cr steels, which are typically used in critical parts of fossil-fuel power plants such as turbines, headers, and main steam pipes.

Study of early P91 dual corrosion in steam and simulated combustion gases from a gas-fired boiler
P91 ferritic steel pipes face dual environments during boilers operation: steam-side and fire-side. This P91 steel assessment differs from the dual studies performed to simulate coal-fired boilers -oxyfuel/steam atmospheres- since the fuel source is ...
