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.

Packaging
  • Standard: Bundled with plastic/corrugated wrapping, wood-crated or palletized.
  • Protection: PVC end caps, VCI (vapor corrosion inhibitor) paper for long-term storage.
  • Labeling: Heat number, size, temper, quantity, and compliance marks (RoHS/REACH).
Value-Added Services
  • Cutting: Precision saw, abrasive waterjet, or laser cutting.
  • Heat Treatment: Custom aging (H900 to H1150M) for target strength/toughness.
  • Machining: CNC turning, milling, threading, grooving.
  • Surface Treatment: Passivation, electropolishing, bead blasting.
  • Testing: Eddy current (ECT), hydrostatic, ultrasonic (UT), PMI (positive material identification).
  • Welding: TIG/GTAW with ER630 filler wire.
Applications
630 seamless tubing is critical in high-performance sectors:
  • Aerospace: Landing gear, actuator cylinders, hydraulic lines.
  • Oil & Gas: Downhole tools, valve stems, chemical injection tubing.
  • Medical: Surgical instruments, implantable device components (biocompatible grades available).
  • Power Generation: Turbine blades, heat exchanger tubes.
  • Industrial: Hydraulic/pneumatic cylinders, bearings, nuclear waste containers.
  • Marine: Propeller shafts, subsea fittings.
Compliance & Certification
  • Mill Test Reports (MTRs) per EN 10204 3.1/3.2.
  • Compliance: NACE MR0175, ASTM A262, AMS 5643.
  • Certifications: ISO 9001, AS9100, PED 2014/68/EU (upon request).
