dignity
Note heat resistance, heat resistance, high corrosion resistance to hot alkalis and acids concentrates. Mechanical strength to withstand the pressure 370−440 MPa products. At ordinary temperature in the air it is covered by a nickel oxide film, which protects the metal from corrosion. Ni and retains the magnetic properties at t ° -100 ° C. It is biologically maloaktiven, making it popular in the food industry, medicine. Its surface after polishing looks very impressive. Plasticity allows the NP-2 range of any section, to expose it to all kinds of processing: cutting, welding, turning, cold-rolled. sulfur impurity impairs the properties of the alloy NP-2, as tends to form a sulfide film on the surface that makes metal brittle at high temperatures.
Production
NP-2 range of 99.5% consists of pure Ni, 0.5% impurities, which include Cu, Si, Fe, Mn, SC Marking «N» means nickel itself, and «P» — semi-finished product. Reference numeral denotes a higher or lower content of impurities.

Known brand N-1, NP-1, NP-2 and others. For the manufacture of a circle using the brand H1, H3, NP-2, NP-3, Ni grade siliceous NC 0.2. NP-2 is produced by melting alloy nickel scrap. Manufacturing range normalizes GOST 083−77 13 «Rods of nickel and siliceous nickel». Under the terms of the order produced in any length. Its surface must be clean and smooth, free from dirt and cracks. The defects must not exceed the size of the tolerance. In place of the fracture circle should be no extraneous inclusions and voids. The edges of the cut should be smooth, chopped edges shall be permitted only in bars with Ø 35 mm. Tubes can only be straight. The value of the permissible curvature is determined by multiplying the length of the articles on the value of the largest curvature in a certain place.
