Petrochemical forgings with dense grain structure, high strength and excellent resistance to high pressure, creep and corrosion are widely adopted for reactors, heat exchangers, towers, subsea drilling & production equipment and transmission parts. This article introduces typical forging materials including 15CrMoR, P91/P92, 316L, 2205, 2507 super duplex steel and nickel & titanium alloys, compares the performance differences between forgings and castings, and clarifies material selection principles for 316L vs 2205, the advantages of 2507 for deep-sea service, and the necessity of quenching & tempering for 42CrMo/35CrMo transmission forgings.
