ABSTRACT
The article reports on several utilities around the world discovering abnormal or aberrant P91 base and weld metal microstructures in their plants. It is said that this can lead to early cracking and failure in critical plant components. Many material suppliers, plant manufacturers and welding companies have failed to perform proper heat treatment, which is critical in achieving full-strength, high-chromium martensitic steels.
