The starting material for fittings shall be fully killed steel,
consisting of forgings, bars, plates, sheet, and seamless or
fusion-welded tubular products with filler metal added and shall
conform to the chemical requirements. Unless otherwise specified
for carbon steel plates and sheet, the steel may be made to either
coarse grain or fine grain practice. Grade WP9 shall be made to
fine grain practice.
