電(dian)(dian)(dian)梯作為(wei)(wei)辦公、生活中(zhong)常(chang)用(yong)到的垂直方(fang)向的運輸工(gong)具，在高層樓(lou)房和公共場所(suo)已(yi)經成(cheng)為(wei)(wei)不可或缺的建筑配備。技(ji)術的發(fa)(fa)展(zhan)及(ji)人民的生活消費水平的提升，也帶動了電(dian)(dian)(dian)梯產業的迅速發(fa)(fa)展(zhan)。2020年中(zhong)國電(dian)(dian)(dian)梯保有(you)量800萬臺，占全球(qiu)(qiu)電(dian)(dian)(dian)梯保有(you)量的40％以上，2020年中(zhong)國電(dian)(dian)(dian)梯產量105萬噸，占全球(qiu)(qiu)電(dian)(dian)(dian)梯總(zong)產量的70％以上。受全球(qiu)(qiu)疫情的影響，2020年中(zhong)國電(dian)(dian)(dian)梯出口量大幅下降為(wei)(wei)7.5萬臺。

基于電梯行業需求，寶鋼自2007年開始，分別與國內知名電梯品牌廣州日立電梯、上海三菱電梯一道，聯合開發了電梯轎廂用超純鐵素體不銹鋼BX439和B443NT產品。前期三菱電梯對B443NT研磨拉絲面板開展了中性鹽霧、加速腐蝕試驗等耐蝕性評價及螺柱焊接、落料、沖孔、折邊等加工評價。評價結果表明，B443NT耐蝕性能與304相當，加工性能完全符合鈑金件流水線加工設備要求。
