Product Description

Brief Introduction
The Cold Rolled Steel 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 Cold Rolled Steel is pre-treated before being cold rolled with a process known as pickling, which uses strong acids to remove scale and other impurities. The Cold Rolled Steel is then passed through rollers to reduce its thickness. Most cold rolling takes place in multiple passes and as the size of the Cold Rolled Steel 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 Cold Rolled Steel may be manufactured in the form of sheets, strips, bars, or other forms.

Q: I already have the county permits and bank loan, but the foundation hasn't been poured. Is it too late to convert to steel?: Steel is going to be a whole different world. You will need to go back to square one and get house plans that are drawn for structural steel. First thing you need to do is find a builder that knows how to build with steel and get an idea of the price.

Q: Search the internet for 'Frost Clipper Knife'. This knife comes in either stainless or carbon steel. I have a friend who has one (stainless steel) and he is very impressed with it, but I have heard that Carbon Steel blades are better? Discuss...: There are different grades of Carbon Steel. A good grade is much harder than Stainless Steel and will stay sharp longer. It is also many times harder to get an edge on than Stainless Steel. I have had both and prefer the Stainless Steel because eventually the Carbon Blade does get dull, and you will wear out a Whet Stone trying to put the edge back on it. The Stainless Steel holds an edge an acceptable amount of time and is easier to sharpen when the time comes. Putting either knife through a can opener sharpener will ruin the edge and make it almost impossible to put another edge on the knife. Look closely and determine the angel of the bevel, then lay the knife bevel flat on a good whet stone and try to take a thin slice off of the stone. Turn the knife over and do the other side so you keep the edge centered on the blade. Keep turning the knife over and taking thin slices until it is sharp. Dress with a good quality sharpening steel.
