Fe white copper Tubes and Pipes

The addition of Fe and Mn in B10 and B30 alloys greatly improves the corrosion resistance of this material. In clean seawater, the alloy can accept water flow rates up to 2.2-2.5%/s. The maximum acceptable speed in the salt solution can reach 4m/s. The alloy can avoid stress corrosion cracking and high temperature point denickel. Therefore, the alloy has good corrosion resistance to clean or polluted sea water and river bay water, and is widely used in heat exchangers that use sea water in power stations, desalination, petrochemical plants, etc.

Grades, characteristics and applications

Alloy Grade	Main features	Application examples
BFe10-1-1	It is a structural iron-nickel alloy with less nickel. Compared with BFe30-1-1, it has higher strength and hardness on the sole, but higher plasticity and similar corrosion resistance	Mainly used in the shipbuilding industry to replace BFe30-1-1 to make condensers and other corrosion-resistant parts
BFe30-1-1	It is a structural copper-nickel alloy with good mechanical properties, high corrosion resistance in sea water, fresh water and steam, but poor workability.	It is used to make pipes for condensers and thermostats working under high temperature, high pressure and high speed conditions in the marine shipbuilding industry.
