ASTM B515-22 — Welded Nickel-Iron-Chromium Alloy Tubes
Procurement reference for welded nickel-iron-chromium alloy boiler, heat-exchanger and condenser tubes under ASTM B515.
Edition control: ASTM B515-22 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 B515 covers welded tube in UNS N08120, N08800, N08810 and N08811 for boiler, heat-exchanger and condenser duties in corrosion-resisting and low- or high-temperature service.
RFQ and Product Controls
- Exact UNS alloy and ASTM B515-22 edition
- Boiler, heat-exchanger or condenser duty and governing equipment specification
- Outside diameter, wall thickness, length and dimensional tolerances
- Automatic welding, post-weld cold work, final annealing and oxide-removal route
- Chemical, mechanical and grain-size requirements for the selected alloy and condition
- Flattening, flanging and required leak or electric examination route
- ASTM B751 requirements, inspection document, traceability, marking and destination
The material identity must remain traceable from the producing heat and lot through manufacture, welding, heat treatment, testing, inspection documentation, marking and final release.
Scope Boundary
ASTM B515 is a welded tube specification, not a welded pipe or seamless tubular route. Equipment design, medium compatibility, tubesheet joint, welding procedure and pressure-code acceptance remain separate controls.
