This specification covers a group of common requirements that shall apply to steel flanges, forged fittings, valves, and parts for piping applications. If the primary melting is required it shall incorporate separate degassing or refining and may be followed by secondary melting, such as electroslag remelting or vacuum remelting. If secondary melting is employed, the heat shall be defined as all of the ingot remelted from a single primary heat. Material requiring heat treatment shall be treated as specified in the individual product specification using the following procedures such as full annealing, solution annealing, isothermal annealing, normalizing, tempering and post-weld heat treatment, stress relieving. Heat analysis shall be used to determine the percentages of carbon, manganese, phosphorus, sulfur, silicon, chromium, nickel, molybdenum, titanium, tantalum, copper, cobalt, nitrogen, aluminum, vanadium, cerium to meet the required chemical composition. The product analysis shall be used to determine if the chemical composition shall conform to the limits of the product specified. Mechanical tests shall be performed to determine the mechanical properties such as hardness, tensile properties, and impact properties.
