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: Can you use regular welding rods when welding stainless steel?Thank you.: You would use stainless steel rod. I have used stainless safety wire that you can buy at the hardware store or Harbor Freight. (Assuming you are TIG welding). I have found that for small jobs it works quite well.

Q: Hi, I would like to know if steel is an important material in desalination plants. If it is, could you specify what type of steel is used (i.e. flat steel products, long steel products, etc). Thanks.: If stainless steels were used they would have to be high grade, high Chromium-Nickel alloyed stainless steels. The best in the range would be the Stainless Steel 316 series with superior corrosion resistance and strength. The downside to this is the expense. Carbon steel may be used but only if reinforced with a more corrosive resistant element

Q: I bought a stainless steel water bottle today. I really like it, but there is no drinking spout, it just has a lid that screws on and off, and an open hole to fill it and drink out of. Is this normal for these bottles? Or do they usually come with a spout to drink from? I don't want to look like an idiot at the gym drinking from this cool bottle with no spout if there's supposed to be one! haha.: That's normal. I'm sure there are caps that you can get that have a built in spout though.

Q: How are steel coils labeled and identified?: To ensure accurate tracking and handling of steel coils throughout their journey, various methods are employed to label and identify them. The labeling and identification process typically consists of the following steps: 1. Initial Marking: At the outset, the manufacturer's name or logo is affixed to the steel coil, enabling easy identification of the producing company. 2.
