摘　　要：通过合理调整材料内控化学成分,控制合适相比,优化生产工艺,成功生产出S32760超级双相不锈钢棒材,成品以固溶处理状态交货,其各项性能指标满足标准要求。同时按照ASTM G48 A法进行腐蚀对比试验,对比钢种包括S32205、S31803、316L、904L。结果显示,试验温度25℃时,S32760与一般双相不锈钢S32205/S31803腐蚀率相当,但试验温度达50℃时,S32760表现出明显优异的耐腐蚀性能。Through chemical composition reasonably adjustment, and optimizing production process, the $32760 super duplex stainless steel bar was successfully developed, with solid solution state as delivery. The performance indexes met the standard requirements. At the same time corrosion contrast test according to ASTM G48 A method, including S32205, S31803, 316L, 904L as comparison steels, was held. Results showed that at the test temperature of 25 ℃, the corrosion rate of S32760 matched S32205/S31803 duplex stainless steel, but when the temperature was up to 50℃, S32760 exhibited excellent corrosion resistance.
