The effect of accelerated cooling parameters on microstructure and hydrogen initiated cracking (HIC) is studied for thick-walled low-alloy steels of strength categories X52–X65 used for manufacturing large diameter pipes intended for operation in hydrogen sulfide media. Optimum accelerated cooling regimes are determined providing formation of a ferrite-bainite microstructure throughout the rolled product’s thickness, exhibiting improved hydrogen cracking resistance. © 2015 Springer Science+Business Media New York

At the Azovstal Metallurgical Combine together with the Bardin Central Research Institute of Ferrous Metallurgy production of thick plate (3266 × 19.1 mm) is being developed for a large diameter gas pipeline of strength category X70. Plates are manufactured using controlled rolling technology with accelerated cooling (CR + AC) instead of previous controlled rolling technology with air cooling. Introduction of CR + AC promotes an increase in average values of energy for failure KV with impact tests on finished metal plate, and also a marked improvement in 3600 rolling mill productivity. © 2013 Springer Science+Business Media New York.

The results of investigation for the influence of the coke quenching method on the coke reactivity were shown. Using thermogravimetry and scanning electron microscopy significant differences of the porous structure and peculiarities of the structure of coke carbon, which forms the pores walls in both wet and dry quenching coke, were discovered. It was established that higher reactivity of wet quenching coke is due to its higher porosity (60 % higher than that of dry quenching coke). © Gusak V., Drozdnik I., Shmalko V., Kaftan Y., 2012.
