ASTM B535-06(2022) — Nickel-Iron-Chromium-Silicon Seamless Pipe and Tube
Procurement reference for UNS N08330 and N08332 seamless pipe and tube under ASTM B535.
Edition control: ASTM B535-06(2022) is the active edition identified in the official ASTM catalogue checked on 1 September 2026. Confirm the authorised publication and purchase-order requirements before use.
Scope in Procurement
ASTM B535 covers hot-finished and cold-finished seamless pipe and tube in UNS N08330 and N08332 for heat-resisting applications and general corrosive service. Material is ordered in the applicable annealed condition.
RFQ and Product Controls
- Exact UNS N08330 or N08332 and ASTM B535-06(2022) edition
- Heat-resisting or corrosive-service duty and governing equipment or piping specification
- Pipe or tube designation, dimensions, wall basis, length and tolerances
- Hot-finished or cold-finished seamless route and required annealed condition
- Chemical, mechanical and hardness requirements for the selected alloy
- Hydrostatic or nondestructive examination and any supplementary requirements
- ASTM B829 requirements, inspection document, heat-and-lot traceability, marking and destination
The material identity must remain traceable from the producing heat and lot through manufacture, seamless processing, heat treatment, testing, inspection documentation, marking and final release.
Scope Boundary
ASTM B535 is limited to the stated UNS N08330 and N08332 seamless tubular routes. Service temperature, corrosion performance, fabrication procedure and design-code acceptance remain project-specific engineering controls.
