Abstract: Ferritic creep-resistant steel, according to ASME Code case Grade 92 (Gr.92), contains 9%Cr (chromium). It has a high creep rupture strength at 600°C for 100 000 h, and is therefore a suitable material for long-term use in a high-temperature and pressure steam circulating coal-fired power plant.
