API2HGR50 (
API 2H Grade 50) steel is a carburizing steel. The carburizing steel is usually a low-carbon steel with a carbon content of 0.15%-0.24%. It is a steel plate for making offshore platform structure.
API2HGR50 offshore platform steel is suitable for surface carburizing and hardening treatment, with good processability, small processing deformation, and good fatigue resistance. This steel is mainly used for making ship hulls, offshore oil production platforms, platform pipe joints and other structural parts.
