General Characteristics
Nickel is a shiny metal with a yellowish hue that is quite expensive because it is difficult to produce. It is resistant to aggressive media and high temperatures. It retains its magnetic properties at very low temperatures. It is in demand in mechanical engineering, but especially wide - in electrical engineering and instrumentation for manufacturing of anodes and cathodes. Stainless steel products would be impossible without nickel alloying. NP-2 rod has insignificant, up to 0.5% impurities. The "N" refers to the nickel itself, and the "P" refers to the semi-finished product. The best-known grades are Н, NP-1, NP-2, etc. The number indicates a certain amount of impurities.
Chemical composition of НП-2 (GOST 492 - 2006).
| Ni | Mn | Fe | Mg | С | Cu | Si | Zn | S | As | Bi | Cd | P | Pb | Sb | Sn |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Not less than 99,5% | up to 0.05 | up to 0.1 | up to 0.1 | up to 0.1 | up to 0.1 | up to 0.15 | up to 0.007 | up to 0.005 | less than 0.002% | less than 0.002% | less than 0.002% | less than 0.002% | less than 0.002% | less than 0.002% | less than 0.002% |
Production
NP-2 is remelted from nickel waste. The bar is produced in accordance with
- non-dimensional drawn 1.5 - 4 meters;
- rolled Ø up to 60 mm 1 - 3 m in length;
- rolled Ø > 60 mm 0,7 - 1,4 m long;
- Of measured length or multiple of measured length within the out of measured length, with a tolerance of +15 mm.
Nickel rod length can be varied upon customer's request. Nickel of N1, NP-2, N3 grades and silicon grade NK 0.2 are used for production. The surface of the product should be smooth and clean, without cracks and dirt. Defects on the surface shall not exceed permissible deviations. The rod shall be supplied only straight. The value of the allowable curvature is determined by multiplying the length of the entire product by the value of the maximum curvature in a given place. The rod shall withstand without deformation the pressure of 380-440 MPa. At the point of fracture, the alloy NP-2 must be free of foreign inclusions and voids. The edges of the cut should be flat, chopped edges are allowed only for bars up to 35 mm in diameter.
Supplies
Prices of chemically pure nickel are considerably higher than those of alloys, therefore NP-2 bars containing 99.5% of nickel plus 0.5% of impurities are the best option for a buyer. Delivered by trench transport, it is stored under a shed or in a room with a roof to protect against moisture, contact with aggressive substances, to protect against mechanical damage.
