The scope of this order covers finished carbon steel flanges. Finished carbon steel flanges differ from unfinished carbon steel flanges (also known as carbon steel flange forgings) in that they have undergone further processing after forging, including, but not limited to, beveling, bore threading, center or step boring, face machining, taper boring, machining ends or surfaces, drilling bolt holes, and/or de-burring or shot blasting. Any one of these post-forging processes suffices to render the forging into a finished carbon steel flange for purposes of this order. However, mere heat treatment of a carbon steel flange forging (without any other further processing after forging) does not render the forging into a finished carbon steel flange for purposes of this order. While these finished carbon steel flanges are generally manufactured to specification ASME B16.5 or ASME B16.47 series A or series B, the scope is not limited to flanges produced under those specifications. All types of finished carbon steel flanges are included in the scope regardless of pipe size (which may or may not be expressed in inches of nominal pipe size), pressure class (usually, but not necessarily, expressed in pounds of pressure, e.g., 150, 300, 400, 600, 900, 1500, 2500, etc.), type of face (e.g., flat face, full face, raised face, etc.), configuration (e.g., weld neck, slip on, socket weld, lap joint, threaded, etc.), wall thickness (usually, but not necessarily, expressed in inches), normalization, or whether or not heat treated. These carbon steel flanges either meet or exceed the requirements of the ASTM A105, ASTM A694, ASTM A181, ASTM A350 and ASTM A707 standards (or comparable foreign specifications). The scope includes any flanges produced to the above-referenced ASTM standards as currently stated or as may be amended. The term "carbon steel" under this scope is steel in which: (a) Iron predominates, by weight, over each of the other contained elements: (b) the carbon content is 2 percent or less, by weight; and (c) none of the elements listed below exceeds the quantity, by weight, as indicated: (i) 0.87 percent of aluminum; (ii) 0.0105 percent of boron; (iii) 10.10 percent of chromium; (iv) 1.55 percent of columbium; (v) 3.10 percent of copper; (vi) 0.38 percent of lead; (vii) 3.04 percent of manganese; (viii) 2.05 percent of molybdenum; (ix) 20.15 percent of nickel; (x) 1.55 percent of niobium; (xi) 0.20 percent of nitrogen; (xii) 0.21 percent of phosphorus; (xiii) 3.10 percent of silicon; (xiv) 0.21 percent of sulfur; (xv) 1.05 percent of titanium; (xvi) 4.06 percent of tungsten; (xvii) 0.53 percent of vanadium; or (xviii) 0.015 percent of zirconium.
