求翻译：90%使用铬系铁合金，而我国的铬资源极度匮乏，铬系铁合金生产的铬矿几乎全部依赖于进口，在铬铁成为不锈钢生产制约因素的情况下，不锈钢生产厂将不得不再折回生产含镍的200、300系列不锈钢，所以就目前中国不锈钢市场生产和消费形势分析，今后很长一段时间300系不锈钢稳定占有不锈钢市场50%～55%的份额，400系所占的市场份额在25%～30%左右，而200系产品市场份额将保持在20%。是什么意思？

90% of the chromium alloy, and our extreme shortage of chrome resources, chromium ferroalloy production of chrome ore almost entirely dependent on imports of stainless steel in ferrochrome production constraints as in the case, stainless steel production will no longer turn back the production plant

90% use chromium are the ferroalloy, but our country's chromium resources extreme deficient, the chromium is the ferroalloy production chrome ore relies on nearly completely the import, becomes the stainless steel production restriction factor in the ferrochrome in the situation, the stainless steel

90% using chromium Department Ferroalloy, and in China of chromium resources extreme lack, chromium Department Ferroalloy production of chromium mine almost all rely on Yu imports, in chromium iron became stainless steel production restricting factors of situation Xia, stainless steel production fac
