Assimilation of Pipe Steel Extra-Furnace Treatment and Casting Technology with Specification for Resistance to H2S Media Under Casting and Rolling Complex Conditions

Abstract

Comprehensive analysis is provided for the effect of production parameters on the manufacture of steel produced under conditions of a casting and rolling complex (CRC) on rolled production hydrogen-induced cracking (HIC) resistance and sulfide corrosion cracking (SCC) in H₂S-media. For the first time, in metallurgical practice under casting and rolling complex conditions a general concept of technology is developed for extra-furnace treatment and casting of steel with specifications for HIC and SSC with simultaneous provision of rolled product cold resistance (KCV at –50°C, KCU at –60°C), and based upon it assimilation of rolled product and oil and gas pipe mass production.
