The organisation of the city appears to have differed from that of other Maya sites and appears to have been geared towards a specialised coastal trade in salt.
Steel is a solid solution, a subtype of chemical mixtures that involve two or more molecules in a solid state that combine to form a single substance while retaining their individual identities. The component metals making up steel are not chemically bonded together. Continue Reading.
Low-alloy steels constitute a category of ferrous materials that exhibit mechanical properties superior to plain carbon steels as the result of additions of alloying elements such as nickel, chromium, and molybdenum. Total alloy content can range from 2.07% up to levels just below that of stainless steels, which contain a minimum of 10% Cr. For many low-alloy steels, the primary function of the alloying elements is to increase hardenability in order to optimize mechanical properties and toughness after heat treatment.
