摘要
介绍了山西太钢不锈钢股份有限公司双相不锈钢管坯的试制工艺、化学成分、组织与性能。试制结果表明,通过控制锻造温度及适当的固溶处理,可以有效解决锻造过程中出现二次奥氏体及金属间化合物的问题。太钢生产的双相不锈钢管坯,其力学性能、抗点蚀性能等与国外同类产品相当,经加工成钢管后,已逐步应用于油气田开采中。
The trial manufacture process,chemical composition,microstructure and properties of duplex stainless steel billet in TISCO had been introduced.The results show that the problem of secondary austenite and intermetallic compounds formed during forging procedure can be effectively resolved through the control of forging temperature and solution treatment.The mechanical properties,anti-pitting character of duplex stainless steel billet produced by TISCO are as well as that of similar foreign products.At present,this product has been gradually used in petroleum and gas exploitation after being fabricated as tubes and pipes.
