Alternative to ASTM A403 WP321H butt weld fittings

Grade Why it might be chosen instead of ASTM A403 WP321H fittings?
ASTM A403 WP304L Not high temperature strength, but resistance to intergranular corrosion is required.
3CR12 There’s only a slight “high temperature” environment…up to between 450 and 600°C.
A403 WP304H There’s only a slight “high temperature” environment…up to between 600 and 800°C.
A403 WP310 Up to approximately 1100°C, the operating temperature is too high for A403 Grade WP321H.
UNS S30815 (253MA) Up to approximately 1150°C, the operating temperature is too high for the ASTM A403 WP321H.
