Product Description

Brief Introduction
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. 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 coil may be manufactured in the form of sheets, strips, bars, or other forms.

Q:I am a complete idiot when it comes to anything musical, so please forgive me if this is a stupid question. I bought my son his first guitar, acoustic and didnt realize until after I purchased it that it has steel strings. Can I have the strings changed from steel to nylon???: Nylon strings are more commonly used for classical style acoustic guitars, and most standard acoustics are set up to use steel strings. Nylon strings have less tension than steel strings so the sound won't be as full as steel strings. You may also notice some loud vibration from the top of the guitar since the strings don't have the proper tension. A guitar made for nylon strings uses thinner wood and is braced differently than one made for steel strings. The nylon strings won't put enough energy into the steel string guitar to make it vibrate correctly and develop the volume and harmonics that steel strings would. EDIT: To answer the second part of your question, it doesn't really matter what type of strings a beginner learns on. Nylon strings will be a little softer on the fingers, but once you build up calluses on your fingers it doesn't hurt anymore. There is no distinct advantage to a beginner learning with nylon strings as opposed to steel strings.

Q:I have a steel support beam can you remove one of the poles . the steel beam set on sender blocks on both side of the foundation. I have three steel beams support beam across the basement,I just want to remove one pole, can that be done.: Steel poles under the steel beam is required for the code in your local building area. No, do NOT remove any pole without checking with your local building dept. They are engineered to carry all the weight of the framing over it. If you chose to remove it without checking with the building dept. you can cause a serious structure problem, even a collapse of the structure. Just a phone call to your local building dept. can answer that question. They normally put a steel pole about every 14'-16' depending on the code in your area. There there for a good reason. Think smarter than the next guy, and you will keep yourself safe and your family also. Hoped this helped you go in the right direction.

Q:How are steel coils weighed?: Steel coils are typically weighed using industrial weighing scales or load cells. These devices are capable of accurately measuring the weight of the coils, whether they are small or large in size. The coils are placed on the scale or load cells, and the weight is digitally displayed or recorded for further analysis or documentation.

Q:I want to buy steel. My problem is i purchase it from a middle man, so i need to know what MIld steel is. What it's real name or specifications is/are. I dont want to end up purchasing Black steel or other stuff i can sell or use...: iron mild steel are not the same but you need iron to make mild steel this is done by the process off a blast furnace were iron ore coke limestone are added coke is coal which has been put into a coking oven to remove some impurities then once the coke, iron ore limestone are mixed this and comes out the bottom of the blast furnace red hot is know as pure iron once you have this you then put it into the BOS Basic Oxygen Steel making were pure oxygen is blown onto the the iron for about 45 min which then turns the iron into steel. hope this helps :o)

Q:The guy at this one pawn shop told me that stainless steel is better because it is just as strong and will not rust. The guy at the other pawn shop said that you need high carbon steel for a good sword because stainless steel breaks easily and that damascis is the best kind of steel for swords.: Stainless steel is not as strong as tempered carbon steel, especially at that length. But damascus steel only looks different. In terms of metal quality, pure modern steel is better in flexibility. Cheness uses 9260 spring steel alloy from high carbon steel. Stainless is rated 440. You can look them up on wikipedia to learn about qualities. Edge retention and hardness is better at the 1095 level or the T10 tungsten steel or tool steel level.

Q:I'm a hiker and cook on a camp fire with a canteen cup. So which would be a better material for cooking on a campfire with, aluminum or stainless steel?: Stainless steel and as to the soot problem, it isn't. Black absorbs heat faster, so if you let the pan get blackened it will heat up better for you. Most people used cast iron for campfire cooking and it was black and worked well. Trouble with cast iron is it weighs and ton and not good for hiking with.
