    alloy steel; carbon steel; fittings; flanges; forgings; general requirement; piping applications; pressure containing parts; stainless steel; temperature service applications—elevated; temperature service applications—high; valves;;

    Rationale

    Remove the restriction hollow from cylindrical parts NPS 4 and smaller that can be machined directly from barstock without and further working or heat treatment.
