Etymology: Gk ouron. the fluid secreted by the kidneys, transported by the ureters, stored in the bladder, and voided through the urethra. Normal urine is clear, straw-colored, and slightly acid; has the odor of urea; and has a specific gravity between 1.003 and 1.035.
My understanding of true Damascus steel is that it's likely two different crystaline structures, one more ductile (so it can compress to absorb more energy without failing) and the other more brittle (which can hold a sharper edge).y understanding of true Damascus steel is that it's likely two different crystaline structures, one more ductile (so it can compress to absorb more energy without failing) and the other more brittle (which can hold a sharper edge).
With good ductility, these grades are suitable for parts involving bending, crimping, or riveting. Since 12L14 is an extraordinary machining steel it has become the favorite carbon metal for machining-especially on light weight lathes. It offers inherent ductility combined with finer surface quality. 12L14 has a smooth cold finish (rolled) surface.
