Throughout this schedule, the expression 'base metals' means: iron and steel, copper, nickel, aluminum, lead, zinc, tin, tungsten (wolfram), molybdenum, tantalum, magnesium, cobalt, bismuth, cadmium, titanium, zirconium, antimony, manganese, beryllium, chromium, germanium, vanadium, gallium, hafnium, indium, niobium (columbium), rhenium, and thallium.
Alloy Classification Rules
Classification of alloys: (a) Alloys of base metals with each other are to be classified as alloys of the metal which predominates by weight over each of the other metals; (b) Alloys of base metals of this section with elements not falling within this section are to be classified as alloys of base metals of this section if the total weight of such metals equals or exceeds the total weight of the other elements present; (c) Sintered mixtures of metal powders, heterogeneous intimate mixtures obtained by melting (other than cermets), and intermetallic compounds are classified as alloys.
Iron vs. Nonalloy Steel vs. Stainless
(a) 'Iron and nonalloy steel' covers iron and steel containing by weight 2% or less of carbon and, except for certain specific steels, less than designated percentages of chromium, manganese, nickel, and other alloy elements. (b) 'Stainless steel' covers alloy steels containing by weight 1.2% or less of carbon and 10.5% or more of chromium, with or without other elements. (c) 'Other alloy steel' covers steels not meeting the definition of stainless steel containing specific minimum percentages of alloy elements.
Welded vs. Seamless Distinction
In this chapter, the word 'welded' encompasses products obtained by any process of welding, including electric resistance welding, whether or not subsequently cold-drawn or cold-rolled (cold-reduced).
