630 Stainless Steel Seamless Tubing - Product Information

(UNS S17400 / 17-4PH Precipitation-Hardening Stainless Steel)

Product Description

630 Seamless Tubing is a martensitic precipitation-hardening stainless steel offering exceptional strength, corrosion resistance, and machinability. The "630" designation (per AMS/UNS) is synonymous with 17-4PH. Supplied in solution-annealed Condition A, it achieves high mechanical properties via low-temperature aging heat treatment (e.g., H900, H1150). Ideal for high-stress, corrosive, and moderate-temperature applications where standard austenitic steels (304/316) lack sufficient strength.
