Q:I bought a steel pendant on eBay, but it turned out to be too shiny.I've read on a couple forums that if I leave it soaked in urine for 2 days, it will get duller.Now, if it really does get duller, will the pendant get rusty afterwards?So is the shiny surface the only thing that prevents it from rusting?Any simple, non-urine ideas on how to make it duller are welcome too.Thanks!
Stainless steel will rust under proper conditions. I live on a boat on salt water, trust me. If the urine works it won't be prone to rusting any more than before. It's not the shine that inhibits rusting with stainless steel, it the % of carbon in the steel, compared to regular steel. IF the urine works it's because it is acidic (a mild acid). Wash it with a small brush and some baking soda to neutralize the acid when your done. A much stronger acid would be swimming pool acid. (Muriatic acid) but be careful you might test a spot with a Q tip on the back. If you try Muriatic acid it would take seconds.Then wash in baking soda water to remove all acid.. SS
Q:Correct me if I am wrong, but steel is an alloy between iron and carbon. Does the carbon in the steel stops the iron from rusting or corroding? Also what is the difference between mild steel and stainless steel?
Mild steel is an alloy. It is the most common form of steel. Mild steel (a so-called carbon steel) is a general term for a range of low carbon (a maximum of about 0.3%) steels that have good strength and can be bent, worked or can be welded into an endless variety of shapes for uses from vehicles (like cars and ships) to building materials. The carbon does not stop the material rusting or corroding. In addition to iron, carbon, and chromium, modern stainless steel may also contain other elements, such as nickel, niobium, molybdenum, and titanium. Nickel, molybdenum, niobium, and chromium enhance the corrosion resistance of stainless steel. It is the addition of a minimum of 12% chromium to the steel that makes it resist rust, or stain 'less' than other types of steel. The chromium in the steel combines with oxygen in the atmosphere to form a thin, invisible layer of chrome-containing oxide, called the passive film. The sizes of chromium atoms and their oxides are similar, so they pack neatly together on the surface of the metal, forming a stable layer only a few atoms thick. If the metal is cut or scratched and the passive film is disrupted, more oxide will quickly form and recover the exposed surface, protecting it from oxidative corrosion.
Q:I had a damascus steel katana made for me and was wondering if I could put gun blue on it to make the steel black and it still work right
There okorder , the true Damascus is a region of spain, which is similar to getting swords made in Pakistan
Q:I want to make a chess set out of stainless steel, but I'm not sure what type of mold I need or where I can go to have the steel melted and molded for me. Any ideas? I live in Southern, NJ.
stainless steel is really hard to work with and will be really expensive to pour as not too many foundries do that. As far as tools go, I know that for e.g.drilling stainless steel cobalt bits are best, but even they don't last for very long. If you use normal drill bits stainless steel will ruin them. So how much metal working skills do you have? I would suggest to use a material you have experience with. Or make a chess set from nuts and bolts. You can buy them from stainless steel and the assembly is easy. See links for a few examples and/or use google to find more.
Q:What are the typical dimensions of a steel coil?
The typical dimensions of a steel coil can vary depending on its specific application and industry. However, common dimensions for steel coils include a width ranging from 0.5 inches to 72 inches, and a thickness ranging from 0.010 inches to 0.625 inches. The inner diameter of the coil is usually between 16 inches and 24 inches, while the outer diameter can range from 48 inches to 72 inches.
Q:How are steel coils processed for edge conditioning or slitting?
Steel coils are processed for edge conditioning or slitting through a series of steps. First, the coil is unwound and flattened to remove any bends or curls. Then, the edges of the coil are trimmed or conditioned to ensure a smooth and straight edge. After that, the coil is slit into narrower strips using specialized machinery. This process allows for the production of various widths of steel strips, which can be used for different applications.
Q:i'm looking into pedal steel guitars, and I would like some suggestions or links and info on what kind i should get.
Try okorder -The Art of Steel Guitar/ Steel guitar players -Take it away Leon- McAuliffe and 'Speedy West' were a couple greats. In the late '50s, Speedy was playing a Fender 1000 Pedal steel. He often did duets with Jimmy Bryant The Fastest Guitar Player In The Country! / note also the 'Emmons Guitar Company':
Q:Which is more reactive? Zinc or Steel? And why?
Zinc. Steel is an alloy consisting mostly out of iron, In the reactivity seris, zinc is more reactive than iron. Therefore, zinc is more reactive than steel
Q:What is the difference between a steel strip and a coil? The steel strip is flat steel, and the steel coil is made of steel. Is that correct?
A steel strip is a steel strip of relative range, and can be called a steel strip when the width is less than 1000.
Q:I am reading the book The Cure For All Advanced Cancers by Hulda Regehr Clark.She writes for example: cancer can be caused by exposure to heavy metals, like nickel and chromium from stainless steel cookware. Stainless steel cookware releases chromium and nickel, two of the most carcinogenic metals.Are there any studies done measuring how much nickel and cadmium can be released from the regular use of stainless steel cookware?Is this a commonly accepted opinion that use of stainless steel cookware is dangerous?If not stainless steel, what kind of cookware to use? I heard that non-stick cookware also releases some harmful chemicals.
The food safety standards for cookware are pretty stringent. Older items may be associated with problems - I know they used to make dishes with uranium-based paint - but food-grade stainless steel is safe.
