Which refineries have used alternatives, and what were the results of those alternatives? Thank you for your reply. Attached: A312 Cr.TP321, A106 Cr.B, A335 Cr.P11, A312 TP316, A335 P11, WP04S
A312-TP321 is equivalent to 1Cr18Ni9Ti; A335-P11 is equivalent to 12Cr1MoV, the latter having slightly better properties. A312-TP316 is equivalent to 0Cr17Ni12Mo2Ti
