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

- Q: How are steel coils stored and transported?
- Steel coils are typically stored and transported in a horizontal position, either on the ground or on specially designed racks. They are often secured with steel straps or bands to prevent movement or damage during transportation. When being transported, steel coils are typically loaded onto flatbed trucks or shipping containers using cranes or forklifts. The coils are then secured in place with additional straps or chains to ensure stability during transit.
- Q: i need the same kind of body jewelry they use in the piercing shop but when i go to order them they say stainless steel, not surgical steel, and i have REALLY sensitive skin so i need to be sure, whats the difference?
- No it's not. I have worked in several different shops, selling body jewelry for years.-All inside malls- Every place I have worked (all specializing solely body jewelry) have used surgical steal. Not 100% on the grade for all items, but *most* were 316. Some items will be stainless or titanium. Typically stainless is cheaper and personally, I'd rather have a variety in metals because not everyone in the world is allergic to nickel, so why not have cheaper stainless items available for others? If you go up to any mall cart and tell them you have a nickel allergy, they should know to only show you surgical steal....unless they're idiots, which unfortunately some of them are. That being said, I have walked into tattoo shops and they have tried to charge me 35$ for a back and ball for my Monroe.....just a solid white gem.....The receptionist tried to argue with me on the quality of surgical steal, telling me, my products are lower grade and that's why she can charge me nearly 4x the amount. Well, I'm telling you guys, it's bullshit. I saw a display item in the original packaging and it was from the exact same company I ordered from. This was a very popular/redound shop in my area. They lie to push their product because they believe they can con you into buying it because they are the ones who pierced you (or in my case, sat at a counter and had me sign a few forms). It's just a bunch of **** guys...seriously, don't fall for it.
- Q: How are steel coils distributed globally?
- Steel coils are distributed globally through a well-established supply chain network. Manufacturers typically ship steel coils to various locations worldwide through ocean freight or rail transportation. These coils are then distributed to customers, including construction companies, automotive manufacturers, and other industries, through local distributors or directly from steel service centers. Additionally, international trade and partnerships play a significant role in the global distribution of steel coils, ensuring a steady supply to meet market demands.
- Q: How are steel coils weighed?
- Steel coils are typically weighed using industrial weighing scales or load cells. The coils are lifted by cranes or forklifts and placed on the scales or load cells to determine their weight.
- Q: I have a knife with 154cm steel on it and I always here that you should put oil on it to keep it from rusting but I am just wondering what kind of oil? And how do I apply it and do I just leave it on there?
- There are several grades of steel and other types of metals used in knives. Like another user said, if it is something like 420 Stainless Steel (a very common knife steel grade), then you should not have to worry about it rusting. I still apply oil to my stainless steel knives though to keep the action smooth. Non-stainless will require oil to prevent rust if you are planning on using them heavily. There is a such thing as knife oil and you can find it online. A lot of car or sportting lubricants will work though. I use Rem Oil, a popular gun oil that you can find at Wally World for about $3 a can. Disassemble your knife. Use a solvent and a cleaning solution to clean off the old oil, dirt, and gunk. I use Hoppes solvent (a solvent that can be found at Wal-Mart for a few bucks) and either pour it into a small shot-glass and dip a toothbrush in it, dampen a wash-rag with it, or pour some in the cap and dab a cotton swab on it. Using one of these tools, I swab down my knives completely, focusing mainly on moving parts and parts of the knife that experiences high abrasion (the lock of a liner lock knife for example). Then I spray it down with Rem Oil. Reassemble the knife and let it sit overnight. The next day, I'll rub off any excess oil from the grips. Usually though, the knife is ready to rock the moment I reassemble it. So that's cleaning knives in a nutshell: take it apart, clean off the old oil and dirt, re-oil it with gun oil, then put it back together.
