Description of material
SG1 is basically commercially pure Nickel with excellent corrosion resistance in both reducing and oxidizing media. Its ferromagnetic behavior offers a low coercive force and good magnetic permeability that, together with good electrical conductivity, allows to find applications in many industrial fields. SG1 is normally produced as Nickel 201 i.e. with a very low Carbon content.
Applications
Thanks to its magnetic properties, SG1 is widely use in the fabrication of several kinds of electronic, electric and magnetic components associated with high resistance to many kinds of corrosion. Therefore, SG1 is suitable to produce solenoid cores or electro- valves where the typical ferritic SS grade don’t offer adequate corrosion resistance. It is also used for fittings, tanks, valves, heat exchangers, parts for food industries and piping/hollows for manipulation/transport of caustic and alkali solutions.
