Product Description

Brief Introduction
The CRC Coil is steel that has been worked below its recrystallization temperature by passing it between a pair of rollers. Recrystallization temperature is the temperature at which grains in the lattice structure of the metal have been rearranged, leaving it free of strain and deformations. The CRC Coil is pre-treated before being cold rolled with a process known as pickling, which uses strong acids to remove scale and other impurities. The CRC Coil is then passed through rollers to reduce its thickness. Most cold rolling takes place in multiple passes and as the size of the CRC Coil is further reduced, its strength and hardness both increase, but its ductility decreases. After cold rolling, heating the metal up in a process known as annealing can restore some of its ductility. The final CRC Coil may be manufactured in the form of sheets, strips, bars, or other forms.

Q: .Yea, so I just saw the old Conan movie with Arnold. Good movie, but I still don't get it. What IS the riddle of steel???I get that like from the begining Conan's dad is like telling him a story about Crom and giants, and people got steel once Crom killef the giants. Then, later on in the movie Conan's talking to his lil' asian homie, and Conan tells him that when he dies... he'll go before Crom, and Crom will ask him what the riddle of steel is, and if he doesn't know it he'll get kicked out of barbarian heaven!But, what is the riddle of steel???C'mon guys... I want to in to barbarian heaven! LolBut, seriously though... what us it???.: Doom answers this question by explaining to Conan that the true strength of steel is in the hand that wields it – in other words, it is the resolve and commitment we bring to a task, not the quality or quantity of tools we use in performing it, that is the most important factor in determining success
