Different Size CD4MCu Flange
this is the welding flange , and the material is CD4MCu . it is also a kind of duplex stainless steel.
the flanges are worked as customer's drawing , and we hot forged the material , then put them into CNC machining , to make the dimension as exactly as drawing.
CD-4MCu is essentially ferrite with a yield strength approximately twice that of austenitic alloy and has high hardness, good tensile ductility and satisfactory impact toughness. The high strength and hardness of the alloy are matched to excellent corrosion resistance and are particularly suitable for use in corrosive (including abrasion and erosion) operating conditions. Alloy CD-4MCu has better corrosion resistance in many corrosive media than CF alloy. It is widely used in strong acid working conditions of oxidation and reduction, and has special resistance to stress corrosion cracking in chlorine environment.
here is the chemical composition:
