Chemical element Ni. Density 8.9% g/cm³ (heavy metal). Nickel belongs to the austenite family. Steel is made corrosion resistant by adding at least 8% nickel. Nickel improves the durability and coating and increases the toughness, especially at low temperatures. Nickel is close-grained, lowers the overheating sensitivity and increases the electrical resistance.
Contract size: 6 mt, currency: US-dollar, minimum price change: 1 US-dollar per mt, delivery date for physical nickel: daily for the 3 month future contract, every Wednesday for the following 3 months and every third Wednesday for the next 15 months (totally 27 months). Quality: primary nickel with 99.8 % nickel content with a chemical analysis according to the ASTM Specifications. Form: cathodes, pellets or briquettes.
On the underlying nickel future contacts, nickel options (calls/puts) have maturities of up to 27 months; declaration date (the last day on which the option can be exercised) is the first Wednesday of the month in which the option matures, delivery date is the third Wednesday in the month of maturity.
This is a collective name for alloys of Nickel and other metals, Cu, Cr, Fe, Mo, with a good heat and corrosion resistance. They are referred to by many trade names. W. Nr. 2.4360 is NiCu 30 Fe, an alloy with approx. two thirds nickel and one third copper. It is both extremely tough and corrosion resistant (sulphuric acid, hydrochloric acid, hydrofluoric acid, saline solutions) and is therefore used in pickling plants, chemical apparatus and sea water equipment. There are also cast iron alloys containing nickel of more than 50%, with about 20% Cr and a significant amount of Co with additives of Mo, Ti, Al and Fe. They are used for high technical and temperature demands. Sheets for various usage can be plated with a nickel-base alloy (explosive plated, roll plated). A range of nickel-base alloys can be found in the steel-iron list. Their product number begins with 2.
This is the collective term for all metals except iron. They are distinguished according to density (above or below 4.5 g/cm³) as heavy or light metals, as low or high smelting, as precious and non-precious non-ferrous metals.
This term has been newly defined with the introduction of DIN EN 10020. Previously it was used for all stainless steels where, apart from carbon, no other alloy was added. Now the term non-alloyed stainless is used for steels which have a higher purity than quality steels, especially with regard to non metallic inclusions. This steel is used mainly for quenching and tempering or surface hardening. There are many regulations in place to control harden-ability, firmness and toughness, so that the highest standards are maintained.
