Description

ASME SB171 UNS C46400 Naval Brass Plate Copper Alloy Foging Disc for Heat Exchanger

ASME SB171 UNS C46400 Naval Brass Forged Disc refers to a circular, solid or ring-shaped forging (disc or blank) manufactured from UNS C46400 Naval Brass, produced to the material requirements of the ASME SB171 specification (which covers copper-alloy plate and sheet for marine applications). In summary, this product is a high-integrity, marine-grade copper alloy forging blank, whose material pedigree is defined by ASME SB171/UNS C46400, used as the starting point for critical components in seawater, high-temperature, and high-pressure industrial systems. If you are sourcing it, always ensure the mill certifies both the chemistry to SB171 and the non-destructive testing (NDT) standards for the forged shape.

Quality Assurance & Testing (per ASME SB171)

When procuring this forged disc, the manufacturer must typically provide:

  • Chemical Analysis Report (verifying Cu, Sn, Pb, Fe, Zn ranges).

  • Mechanical Test Certificates (Tensile and Hardness).

  • Ultrasonic Testing (UT) – to ensure internal soundness (no voids or laminations in the forging).

  • Hydrostatic/Pressure Testing (if intended for pressure-retaining parts).

  • Dimensional Inspection – verifying outside diameter (OD), inside diameter (ID if ring), and thickness conform to the forging print.


Application

  • Marine Hardware: Propeller shafts, stern tube bushings, and pump housings.

  • Valve Components: Valve seats, stems, discs, and flanges for high-pressure seawater piping (per ASME B16.24).

  • Industrial Fasteners: Heavy-duty nuts and bolts where galling resistance is required.

  • Heat Exchangers: Tube sheets and baffle plates.

  • Power Generation: Condenser components and turbine fittings.
