ASTM B466 ， ASME SB466 C70600 Copper Nickel B.W. Pipe Fittings
同昌集团供应 ASTM B466/ ASME SB466 Buttweld pipes fittings， for example 180° / 90° / 45° Elbows， Equal Tees， Reducing Tees， Concentric Reducers， Eccentric Reducers， Caps and so on.
This specification B466/SB466 establishes the requirements for seamless copper-nickel pipe and tube in straight lengths， suitable for general engineering purposes. The alloys involved are copper alloys UNS Nos. C70400， C70600， C70620， C71000， C71500， C71520， and C72200.
This page is talked about the C70600 pipe fittings， with some good mechanical properties， which have good resistance to stress corrosion cracking.

A At 0.5 % extension under load
B Rockwell hardness values shall apply only to tube or pipe having a wall thickness of 0.020 in. [0.5 mm] or over and an outside diameter of 5⁄16 in. [8 mm] or over. For all other tube no Rockwell hardness values shall apply.
C Although no minimum grain size is specified， the product must nevertheless have fully recrystallized grain structure
Characteristics and Applications
1.C70600 this material prevents against seawater corrosion， high anti-fouling properties against sea microorganism. With good corrosion resistance， especially in sea water.Widely applied to offshore and related industries such as ship-building & repairing， petrochemical， natural gas and so on.
2.With good cold working capacity. Suitable for high temperature service.What's more， be used in areas where stainless steel cannot be used due to chloride stress-corrosion cracking (CSCC) and in other parts requiring high levels of corrosion resistance.
3.With great resistance to sea water corrosion， applicable for condenser for ship， copper 90/10 and copper 70/30 are for sea water condenser systems， heat and water supply， chemical industry， desalinator etc.
