EGrade TP347LN shall have an Nb content of not less than 15 times the carbon content.

FGrade TP348 shall have an Nb + Ta content of not less than 10 times the carbon content and not more than 1.10%.

GGrade TP348H shall have an Nb + Ta content of not less than 8 times the carbon content and not more than 1.10%.

HGrade TP444 shall have Ni + Cu = 1.00 max.

IGrade TP444 shall have Ti + Nb = 0.20 + 4(C + N)–0.80.
