摘　　要：开发了一种可同时满足上甲板和内底板使用要求的原油油船货油舱用D36-RCW耐腐蚀钢,并对其进行了检验,其力学性能和焊接性均满足要求,并且具有优良的耐腐蚀性能,在内底板腐蚀环境下腐蚀速率为0.3 mm/a左右,上甲板腐蚀环境下25 a外推腐蚀量小于2 mm。The corrosion resistant steel of D36-RCW was developed which can be used at upper deck plate and inner bottom plate for cargo oil tanks of crude oil tankers. This steel has been tested according to the ＂Test procedures for qualification for corrosion resistance steel for cargo tank in iol tankers ＂issued by the China classification society （CCS） , the experimental results show that the mechanical properties and welding performance and corrosion resistant properties of the steel all meet the requirements of CCS, the general corrosion rate of this steel plate was 0.3 mm/a in the corrosion environment corresponding to the inner bottom plate, the predicted corrosion rate for 25 a was less than 2 mm in the corrosion environment corresponding to the upper deck plate.
