Procurement reference for wrought UNS N06333 welded pipe under ASTM B723.
Edition control: ASTM B723-25 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 B723 covers wrought UNS N06333 nickel-chromium-molybdenum-cobalt-tungsten-iron-silicon alloy in welded pipe form for heat-resisting applications and general corrosive service.
RFQ and Product Controls
- UNS N06333 and ASTM B723-25 edition stated exactly
- Heat-resisting or corrosive-service duty and governing equipment or piping specification
- Pipe size, wall thickness, length, ends and dimensional tolerances
- Flat-rolled starting material, automatic welding without added filler and final condition
- Chemical, mechanical, hardness and flattening requirements
- Pressure or electric examination when activated by the product specification or order
- ASTM B775/B775M requirements, inspection document, traceability, marking and destination
The material identity must remain traceable from the producing heat and lot through manufacture, welding or seamless processing, heat treatment, testing, inspection documentation, marking and final release.
Scope Boundary
ASTM B723 is limited to the UNS N06333 welded-pipe route. It does not establish equivalence to other heat-resistant alloys, does not cover seamless product and does not replace weld-procedure, corrosion or design-code qualification.
