First, man discovered Copper, a very malleable and conductive metal. Then he accidentally alloyed it with tin to form Bronze. Causing a surge in the interest of the different metals that he could make. Which lead to the Alchemists of that time period learning to forge Iron, which gave way to the rise of an entirely new Age. The Iron Age. Iron would eventually give way to the rise of steel in modern times. Steel is created by alloying Iron with various element (most notably carbon) to enhance or impart properties to the metal, hardness, strength, and corrosion resistance in the case of Stainless Steel. One of the earliest examples of this to survive to this day entirely intact is the Iron Pillar of Delhi, though it is not a true stainless steel, as its corrosion resistance comes from a high phosphorous content, not through the addition of chromium as in modern Stainless Steels.
Stainless Steel is used for a myriad of things from surgical implements, to aerospace components, and even in harsh saltwater environments that would destroy normal steels in a matter of weeks. The particular alloy we use is 303 Stainless, which has been developed specifically for its machining properties. It is primarily used in the fabrication of fittings and fasteners, where it’s excellent machining qualities allow it to form superb threads and hold tight tolerances.
A Stainless Steel d20 weighs in at approximately 558 grains.
