Nickel — shiny metal with a yellowish hue, quite expensive due to the complexity of preparation. It is resistant to corrosion, high temperatures. At very low temperatures retains the magnetic properties. Sought-after engineering, but especially well — in electrical engineering and instrument for the production of anodes and cathodes. Stainless steel metal would have been impossible without doping nickel. NP-2 has a small bar, and 0.5% impurities. By marking «N» refers to nickel itself, and under «P» — semi-finished product. The most famous brand H, NP-1, NP-2 and others. These numbers refer to the content of certain impurities.

NP-2 is remelted nickel waste. Rod is manufactured in accordance with GOST 083−77 13 «Rods of nickel and siliceous nickel». Produced bars the following parameters:
- Drawn off-gauge 1.5 — 4 meters;
- rolled up to Ø 60 mm 1 — 3 m long;
- rolled Ø> 60 mm 0.7 — 1.4 meters;
- measuring length or the length of a multiple dimensional in the borders of off-gage, with a tolerance of + 15 mm.
Upon request, a nickel rod length can vary. For the manufacture of used nickel grades H1, NP-2, H3, flinty — NC 0.2. The surface of the product should be smooth and clean, free from cracks, dirt. Defects on the surface, should not exceed the tolerance. Bars deliver only direct. 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. The bar must withstand without deformation the pressure 380−440 MPa. In place of the fracture of NP-2 fusion must be free of extraneous inclusions and voids. The edges of the cut should be smooth, chopped edges shall be permitted only in those bars with diameter up to 35 mm.
Nickel prices chemically pure substantially exceed the value of alloys, so the NP-2 rods, containing a 99.5% nickel, plus 0.5% of impurities, it is the best option for the buyer. Deliver it rytym transport. warehoused under a canopy or in a room with a roof to protect from moisture, contact with aggressive substances, to protect against mechanical damage.
