High strength low alloy (HSLA) steels were originally developed to reduce the weight of automobiles. These steels have higher mechanical properties than the low-carbon steels that they replaced. True False Composite materials are composed of two or more different materials that act together to produce properties that are different from, and superior to those of the individual components. True False There are several methods for classifying tool steels; they are: according to the quenching media used, according to alloy content, and according to application. true false Addition polymerization, also referred to as cross-linked polymerization, is a process capable of forming long chains of molecules as well as forming bonds between or across chains; the chains of molecules are cross-linked. True False The aluminum alloy designated as 5056-H28 means the following: this is a non-heat-treatable alloy of aluminum and magnesium, that has not been modified where 56 represents the specific alloy. The "H2" means that the alloy is strain hardened and partially annealed and the "8" means that the alloy is in full hard condition. True False
