Alloy Steel materials are used in many applications, particularly in the power generation industry and petrochemical industry, not only for their tensile strength, corrosion resistance and resistance to high temperatures, but also for their economic profitability. Grades P-11, P-22 – P-91 and P-92 are predominant grades for the energy industry, while grades P-5 and P-9 are more commonly used in refinery processes.
