SPCG COLD ROLLED STEEL
Cold Rolled Steel is steel thathas been worked below its recrystallization temperature by passing it between apair of rollers. Recrystallization temperature is the temperature at whichgrains in the lattice structure of the metal have been rearranged, leaving itfree of strain and deformations. Cold Rolled Steel is pre-treated before beingcold rolled with a process known as pickling, which uses strong acids to removescale and other impurities. The Cold Rolled Steel is then passed throughrollers to reduce its thickness. Most cold rolling takes place in multiplepasses and as the size of the Cold Rolled Steel is further reduced, itsstrength and hardness both increase, but its ductility decreases. After coldrolling, heating the metal up in a process known as annealing can restore someof its ductility. The final Cold Rolled Steel may be manufactured in the formof sheets, strips, bars, or other forms.

- Q: i found a similar question asking what metals were in stainless steel but i don't know if they are the same.... they probably aren't.
- steel is iron with a little bit of carbon mixed in. how much carbon determines the hardness of the steel. stainless steel is the same mostly, it has nickle and chromium added in to make it corrosion resistant.
- Q: I've heard on some 1911 forums that the slides of Armscor guns are now extruded. What is extruded steel? How is it made? Are they strong (4140carbon steel was used in the process).

- Q: So today I was bored and was reading a shotgun shell box,the box was slug 12ga.I noticed it said not to be used in Damascus steel or twist barrel.It was to my understanding that Damascus steel is very strong and many stories came from what it could cut when used in a blade or sword.The little bit of info that i could find was that Damascus used earlier in the turn of the century on shotguns should not be fired unless special maintenance has been given and check out by gunsmith.So is Damascus not strong like i thought and not be able to handle higher pressure or why the reason for the warning?*
- Damascus steel in gunmaking Prior to the early 20th century, all shotgun barrels were forged by heating narrow strips of iron and steel and shaping them around a mandrel.[22][23] This process was referred to as laminating or Damascus and these barrels were found on shotguns that sold for $12.[22][23] These types of barrels earned a reputation for weakness and were never meant to be used with modern smokeless powder, or any kind of moderately powerful explosive.[23] Because of the resemblance to Damascus steel, higher-end barrels were made by Belgian and British gun makers.[22][23] These barrels are proof marked and meant to be used with light pressure loads.[22] Current gun manufacturers such as Caspian Arms make slide assemblies and small parts such as triggers and safeties for Colt M1911 pistols from powdered Swedish steel resulting in a swirling two-toned effect; these parts are often referred to as Stainless Damascus.[24]
- Q: Can steel coils be used in electrical applications?
- Yes, steel coils can be used in electrical applications. Steel coils are often used as magnetic cores in transformers and inductors, which are essential components in electrical circuits. The steel used in these coils is typically a type of high-quality electrical steel that has specific magnetic properties, such as low core losses and high permeability. These properties allow the steel coils to efficiently transfer electrical energy between different components of the circuit. Additionally, steel coils can also be used in other electrical applications, such as in the construction of electric motors and generators. Overall, steel coils are widely utilized in electrical applications due to their magnetic properties and their ability to handle high currents and temperatures.
- Q: for my engineering project I have been asked to design a method of suspending a TV of weight 14Kg from a gantry, the TV must be 5m below the gantry. My team have decided to use as a suspension method a steel cylinder of outer diameter of 10cm and an inner diameter of 8, however we now need to work out both the max stress and strain and the actual stress and strain. and help would be useful
- In most engineering calculations we have to make some assumptions about ideal behavior of a material otherwise we would not be able to simplify our equations to manageable sizes. Your steel cylinder (which I'll call a pipe) is made of a certain type of steel. That steel type has property tolerances listed in a steel manual to help you know about your steel before you begin. You'll need to know the cross-sectional area of the pipe and the weight of the TV to determine an average stress on the pipe. Obviously the weight of the TV is the force it generates. The force is its mass x gravitational acceleration. Since we typically think of steel as an elastic material, we think of it stretching like a rubber band or a spring. You pull it down with a TV and it deflects a certain amount, and will return to its original length when the TV is removed. It is typical to assume that all steel, regardless of its strength, has the same value for this elastic property. It is commonly referred to as the elastic modulus. This value will help you determine what type of strain occurs under what type of stress. So, once you have the stress, you can get the strain by using the elastic modulus. Once you have the strain you can determine the deflection based on the pipe length. Having the steel properties will help you determine how close your TV comes to stressing the pipe to its yield stress. If you reach a yield stress, your steel will deflect, but when you take the TV off it will not return to its original shape. I hope I've helped outline some of the things you'll need to do for the project, I tried not to give away specifics so that you can actually engage your brain around the project. Enjoy, learn a lot, and realize that this skill could easily turn into a career where you are designing projects that when done correctly save people's lives every day of the year.
- Q: Which is used for what?Differences as far as style etc.???Better in your opinion and why??I'm just beginning to look at guitars i might be able to get at christmas if i'm still committed..i've been looking online.,,,,NYLON or STEEL STRINGED ACOUSTIC GUITAR????Thanks.
- Well first off, a nylon, or classical guitar, has nylon strings and a steel, or acoustic guitar, has steel strings (duh lol). A classical is used primarily for classical music. Its body is also a bit differently built then an acoustic. The classical technique primarily uses fingering, not pick strumming, since nylon is a weaker material and can break relatively easily with a pick. Now an acoustic is is a bit different. The body is built a bit more sturdier than a classical so it can take the larger tension of the strings. Acoustic guitars are used in a wide range of music genres, ranging from Country to Rap. So if your not into classical music, an acoustic is your best bet. Remember, NEVER try putting steel strings on a classical guitar, since the tension of the steel strings can break the guitar (i've seen it happen lol).

- Q: How are steel coils inspected for camber?
- To ensure the quality and suitability of steel coils for further processing, various methods are employed to inspect their camber. One commonly used approach is visual inspection, where trained inspectors carefully examine the coils for any visible indications of camber. They search for any deviations from a perfectly straight surface, such as bows or curves, which serve as signs of camber. Another method involves the use of specialized equipment, including straightedges, measuring tapes, and laser devices. Inspectors place the straightedge along the length of the coil to assess any gaps or spaces between the coil and the straightedge. If a significant deviation is detected, it signifies the presence of camber. Measuring tapes are also utilized to measure the distance between the coil and the straightedge at multiple points along its length. This enables inspectors to ascertain the extent of camber and determine if it falls within acceptable tolerance limits. In some cases, laser devices are employed to provide a more precise measurement of camber. These devices emit a laser beam that reflects off the surface of the coil and is subsequently analyzed to determine the presence and magnitude of camber. Furthermore, advanced technologies such as computer vision systems and artificial intelligence algorithms are now being integrated into the inspection process. These technologies have the capability to analyze images or videos of the steel coils and automatically detect any camber, thereby delivering accurate and efficient inspection results. In conclusion, the inspection of steel coils for camber involves a comprehensive approach that combines visual inspection, manual measurements using straightedges and measuring tapes, and the utilization of advanced technologies. This multifaceted approach ensures effective detection and control of camber, thereby upholding the quality and integrity of the steel coils.
