Industrial Copper-Nickel Alloy Ring SB171 C70600 (90Cu/10Ni), Forgings Used In Marine And Seawater Systems
Short Introduction
SB171 C70600 (90Cu/10Ni) forged copper-nickel alloy rings are high-performance industrial forgings engineered for marine and seawater service. Featuring outstanding resistance to seawater corrosion, bio-fouling and erosion, they deliver stable mechanical strength and excellent pressure resistance under harsh offshore and coastal working conditions.
Widely applied in seawater cooling systems, shipbuilding, desalination plants, power stations and subsea piping connections. Supplied with standard compliance, precise machining and complete material test reports for critical industrial projects.

Heat Treatment of C70600 (90/10 Cu-Ni, SB171 Forged Rings)
Standard: ASTM B171 / ASME SB171 (Forged & Annealed Condition)
Annealing (Stress Relief & Softening) — Most Common for Forged Rings
1. Purpose:
Relieve forging/welding residual stress
Soften material, improve ductility & machinability
Stabilize dimensions for marine/seawater service
2. Parameters:
Temperature: 600–750 °C (1110–1380 °F)
Hold Time: 2–4 hours (depends on ring thickness)
Cooling: Furnace cool or slow air cool (avoid rapid quench)
3. Result:
Hardness: ~85–95 HB (45–55 HRB)
Elongation: ≥30%
Balanced strength & corrosion resistance
Application of C70600 Copper-Nickel Alloy Ring
