At the request of the consumer, chromium X99N1 is produced with a mass share nitrogen not more than 0.005%.
By agreement of the manufacturer with the consumer, chromium of the X99N1 grade is manufactured with weight fraction of nitrogen not more than 0.015%; grades X99N5 with a mass fraction of chromium less than 98.5%; grades X97.5% with a mass fraction of aluminum up to 5% and chromium at least 94 %.

The amount of detail passing through a sieve with a cell size of 10x10 mm should not exceed 10% of the mass of the party. Chromium is made crushed in pieces weighing no more than 10 kg. The surface of pieces of chromium should not have pronounced inclusions of slag, Refractories and other foreign materials. In the fracture, the chromium should be dense. Nana The surface of the pieces is allowed oxide captivity. At the request of the consumer chromium They are made from the oxide film surface of the pieces.
