FAQ
Grade 22 is suitable for moderate high-temperature applications, while Grade 91 is designed for extreme high-temperature and high-pressure conditions with superior creep resistance.
These grades are primarily used for high-temperature applications, but additional treatments can enhance their suitability for specific low-temperature conditions.
These sheets are widely used in power generation, petrochemical plants, refineries, and industrial equipment fabrication due to their thermal and mechanical properties.
