UNS S17400 / 17-4PH Precipitation-Hardening Stainless Steel
630 seamless tubing is a martensitic precipitation-hardening stainless steel offering exceptional strength, corrosion resistance, and machinability. Supplied in solution-annealed Condition A, it achieves high mechanical properties via low-temperature aging heat treatment. Ideal for high-stress, corrosive, and moderate-temperature applications where standard austenitic steels lack sufficient strength.
