The production process and technical indicators of super thick 12Cr2Mo1R (HIC) steel plates for hydrogen-contacting equipment was introduced. The effects of heat treatment process and the structure of the steel plate on simulative PWHT and the tendency to temper embrittlement were investigated. The chemical composition and mechanical properties of 118 mm thick steel plate were analyzed. The results show that 12Cr2Mo1R steel plates for super thick hydrogen (HIC) equipment have uniform composition, low content of inclusions, excellent comprehensive mechanical properties and low sensitivity to temper embrittlement.

The self-developed water-cooled mould was used for the development test for super thick bridge steel in Nanyang Hanye Special Steel Co., Ltd. Fine and even internal structure of the steel plate was obtained through composition design, process design for rolling, heat treatment, adopting the development and research process of 100t converter-mould casting-3800mm mill-heat treatment. The performance indexes met the requirement of the relevant national standard. The 150mm Q370qE-Z35 bridge steel plate with large single weight was successfully developed. Source

CCT curves of SA387Gr.22Cl.2 heavy thick steel plate for critical hydrogen vessel were measured, cooling rate at 1/2 thickness under different thicknesses of SA387Gr.22Cl.2 steel plate was simulation calculated, the minimum cooling rate (critical cooling speed) of bainite formation was determined. The results show that the minimum cooling rate of bainite formation is 1 ℃/s and the critical normalized thickness after air cooling is 50 mm. More than 200 mm thickness, the critical cooling intensity increases sharply, core section will appear ferrite and within 2% content the polygonal ferrite no significant effect on the mechanical properties of the steel. ©, 2015, Chinese Mechanical Engineering Society of Heat Treatment.
