近日,我司一批超纯铁素体S44400/SUS444不锈钢无缝管成功发运给国内某环保设备制造商, 用于生产火力发电厂用的环保设备。
虽然我司技术人员严格控制产品生产的全流程(包括炼钢的成分设计,冶炼工艺,热加工工艺,冷加工工艺等), 但生产过程中仍然产生了许多问题:比如热轧棒材裂纹,热轧成材率过低,冷加工管体断裂,开裂,冷加工成材率过低等。但最终所有问题都得到了圆满解决,顺利按质按量的完成了合同。 管子的所有检测项目,都优于标准要求。完全达到了此材质的正常性能。此批货物的成功发运,标志着我公司成为国内唯一能批量生产S44400/SUS444不锈钢无缝管的厂家。
S44400/SUS444无缝管,导热性优于304及316(高30%),热膨胀系数小,抗氧化强,应力腐蚀基本免疫,耐氯离子点腐蚀性能优异。因此特别适用于制造环保,石化,化工等行业的换热器。一般认为,铁素体不锈钢无缝管都比较脆,容易开裂,不容易焊接,冷弯,胀接等冷加工成型难。但实际只要管子的产品性能达到了材料应有的正常值,对产品的所有加工都不会产生任何问题。
