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:Steel navel rings! what to do!?
Surgical stainless steel 316LVM is good, 316L is nowhere near in quality. Its very unusual for someone to have a reaction to surgical steel. Avoid plain stainless steel. Titanium is better, tougher and lighter. And contains less nickel than surgical steel, pretty close to nothing. Its pretty much impossible to be allergic to good quality titanium. Niobium contains no nickel, but only comes as CBRs, and is pretty expensive and unusual. Silver and gold should be avoid in piercings. They have to mix it with so much other junk so that its strong enough, really high nickel content.
Q:What is the best steel for making knives?

Q:Ways to damage steel?
There are plenty of ways to damage/weaken steel... shear or tensile force, fatigue, temperature, corrosion, grinding, etc... there are even dozens of ways to do each of the things I just listed. But in the case you suggested, with the steel being very close to skin... a simple pair of bolt cutters would probably be the easiest.
Q:How to tell if something is Steel?
If it rusts, magnetic, hard, heavy with high melting point I reckon yourve found mild steel.
Q:Can cold rolled galvanized steel coils be acid washed after oxidation?
If it has been galvanized, it can not be pickled, and if it is pickled, it may corrode the zinc layer
Q:Infi steel tactical folders?
infi is a brand name steel. They have it specially made and the composition is supposed to be a secret though it is similar to 52100. I have used knives from Busse and their sister company Swamprat Knives. Both companies make good knives, even if their advertising may be a bit odd. They are pricey, but are also very good knives with good steel and ergonomics. If you have the money they are a good option. I don't know if Swamprat still makes knives, but I have a 4'' folder from them in s30v that is great. Benchmade makes some great knives as well, though not nearly a custom as Busse. Take a look at the 913, a 3.6'' D2 blade that was a spring release and G10 handle for a good price. An excellent knife.
Q:pedal steel guitar...?
I agree with everything that Lester said. Another thought is to consider starting on a lap steel guitar rather than a pedal steel - its related, a little easier to learn on, and less expensive. Once you get proficient on the lap steel, you can move up to the pedal steel. Good luck!

Q:are surgical stainless steel and surgical steel the same thing?
There are several different grades and specifications that are referred to collectively as surgical steel, or Surgical stainless steel Non-stainless steel is not used for piercings and sutures and the like, because of the obvious reason that it tends to rust. The most common grade referred to as surgical is 316L, which is also used for food handling equipment. 316L is tough and very durable and has outstanding corrosion resistance. But it is moderately expensive. Very cheap body jewelry may be made out of cheaper grades of stainless steel like 304 or even the dirt-cheap 409. 304 is less corrosion resistant than 316L ; Almost nothing good can be said of type 409, except that's it cheap. 409 is not technically known as surgical, but some manufacturers may claim it is, to increase their asking price and also to cause buyer confusion. Surgical tools, which are not meant to be implanted, are usually made of the well known 440C, which is extremely strong and excellent at holding and edge, but it is not very corrosion resistant and it is brittle. 440C is not usually considered surgical. It's also used to make kitchen knives.
