设计及制备了2mm厚S32760超级双相不锈钢冷轧板。对国产及进口冷轧板的化学成分、常温力学性能、金相组织、杯突值、应变硬化指数、腐蚀性能及焊接性能进行了对比测试。结果表明,国产板材各项性能指标达到ASEMSA240标准及工程指标要求,与进口板材相当,可以替代进口产品用于相关设备的生产及制造。
Design and preparation of 2mm thick S32760 super duplex stainless steel cold-rolled plate. The chemical compositions, the mechanical properties at room temperature, microstructure, cup projection, strain hardening index, corrosion resistance and weldability of domestic and imported cold-rolled plates were compared and tested. The results show that the performance indicators of domestic plate meet the ASEMSA240 standards and engineering requirements, which is equivalent to imported plates, which can replace the imported products for the production and manufacture of related equipment.
