摘要： 江苏耐尔集团有限公司是一家高科技企业集团，集国内外冷热加工之优点，采用超细晶纳米结构合金材料和技术生产的高强度耐磨、高温耐热、超低碳双相耐腐蚀钢制造的成套设备和备品备件，广泛应用于冶金、电力、矿山、环保、建材、造纸、航道、军工等企业。集团下辖10家公司，实施一企一品、集团化经营战略，拥有各类铸造、锻造、热处理、精机加工等现代化高新精生产和检测、试验设备321台套，满足集团公司产学研之需求，确保产品在每一道工序的每一个工位上“零缺陷”生产和检测。
最近，耐尔集团联合中科院成功开发出CASN亚稳合金三防系列产品。CASN亚稳合金三防系列产品主要应用于石油开采和运输过程以及化工、工矿等行业，可用于油田钻井用柴油机、柴油机发电机组等，油田领域可用于自喷井、抽油井、注水井等，其防蜡、防垢、防腐技术属于国内外首创，可提高采油产量，节油减排效果良好，还可延长发动机使用寿命。
目前，该产品已在大庆油田、吉林油田、辽河油田、塔里木油田等20家油田近300多口油井使用。使用单位认为，三防装置结构新颖、效果显著、安装方便、安全可靠、投入产出比高，是“节能、安全、环保”的产品。
