摘要
在抗H2 S -HCN -H2 O系应力腐蚀用钢 12Cr2AlMoV钢的基础上开发出来的 0 8Cr2AlMo钢具有和 12Cr2AlMoV钢相当的抗硫化氢应力腐蚀开裂的能力 ,同时还具有比碳钢与12Cr2Mo1钢高的抗循环水、软化水及盐酸水溶液的耐蚀性。由于合理的化学成分和优良工装及精炼工艺条件使0 8Cr2AlMo钢的纯净度大大提高 (夹杂物 <1 5级 ) ,硬度降低 (<15 0HB) ,并配有专用的焊接材料 ,使其具有良好的可焊性和制造性能 ,可广泛用于制造石油炼制系统热交换器管束 ,使用温度范围为 - 6 0℃到 5 0 0℃。
Cr2AlMo Steel is the newly developed low alloy steel based on 12Cr2AlMoV steel ,which has high resistance to SSCC in wet H 2S environment,and low corrosion rate under cooling water comparing with carbon steels such as 20g.08Cr2AlMo steel also has good weldability and machinable for produceing heat exchanger with special welding rod and wire.It has been widely used in oil refineries.The using temperature range is from -60℃ to 500℃.
