Stainless steel containing 0.2 to 0.5% niobium,uggs nederland, life can be increased by 10 times more than high strength actinides. Therefore, the structure of consumption in Japan began ferroniobium significant changes in Japan in the early 1980s, mainly for ferroniobium actinium on oil and gas pipelines, oil pipe production tasks was insufficient to reduce the amount of niobium iron, from the early 1980s, the total volume accounted for 65 ferroniobium % to the late 1980s 35%, i992 was only 27, ferro-niobium and stainless steel in the early 1980s by the amount of 7 to 30 last year, the production of niobium plate and sheet iron consumption rose from 35 to 40 last year. % (Table 5). 2 sets of metal niobium box set is the largest use of rubidium-made superconducting materials, part of the covering material for nuclear fuel.
