Product Description:

PPGI is made by cold rolled steel sheet and galvanized steel sheets as baseplate, through the surface pretreatment (degreasing, cleaning, chemical conversion processing), coated by the method of continuous coatings (roller coating method), and after roasting and cooling. PPGI is light, beautiful and has good corrosion resistant performance, can be directly processed also, ppgi provides the construction, shipbuilding, vehicle manufacturing, furniture industry, and electrical industry a new material, while ppgi has good effects on the areas of replacing wood with steel, efficient construction, energy saving, prevent pollution etc.

Q:what is the advantages in using mild steel as raw material in an experimental machining?
*Mild steel is ductile and can be easily machined. Generation of heat is less than that of steel machining.So, the tool can have better life and you can do more machining. Cost factor is of prime importance as other steel are more costly than Mild steel. Mild steel, a grade of steel that does not harden when heated and chilled with cold water, so further machining can be easy. Mild steel is easily available.You will find it in your scrape yard. No need to change the tool repeatedly and no special tools are required for machining. Above is the comparisation between alloy steel,SS and superalloys. Cutting speed and feed does not required special skills.
Q:Is there Non-Corrosive stainless steel?
Maybe okorder.com Hope this can help you.
Q:Why does stainless steel get rusty?
You can rub the rust off with anything, from steel wool to Ajax. Although if you've previously used steel wool to clean it, that could be why it rusts. We had that problem manufacturing stainless steel railing and had to put it together on an aluminum table and polish welds with grinding wheels that never touched steel. What rusts are steel particles picked up on the stainless surface. Another possibility is that some stainless is more magnetic and usually also heat-treatable. It has just enough chrome in it to classify as stainless but can get minor surface rust. Not nearly as much as plain steel, though. Use a scouring powder like Zud or Barkeepers Friend and a cloth or sponge to polish if it's a sheetmetal surface rather than a bar grille, because these have oxalic acid and no bleach. They don't leave corrosive traces of chlorine behind. In fact, oxalic acid reduces rust to iron powder. Which is really neat if you need to clean a small rusty item--stir one of these powders into water, drop in the rusty piece and check it from time to time. Rinse off any abrasive powder, dry it well and oil it. When the rust is gone, it leaves a fine matte finish behind.
Q:which is heavier: concrete or steel?

Q:What makes Steel stronger than Iron?
Cast Iron' is typically brittle, while 'Maleable Iron' has a small percentage of carbon which allows it to be hammered and formed. Steel is an alloy that consists mostly of iron and has a carbon content between 0.2% and 2.1% by weight, depending on the grade. Carbon is the most common alloying material for iron. Steel is a crystalline structure of iron molecules interspersed with carbon molecules. This is properly known as cementite. The hardness and malleability of steel depends not only on the carbon content, but on how the carbon and iron molecules are arranged to one another. Internal stresses in the steel's crystalline structure will increase or decrease depending on the temperature it is subjected to and the rate at which molten steel is cooled. This 'tempering' can increase the strength of the steel at the expense of brittleness.
Q:surgical steel or sterling silver belly button rings?
Sterling silver is not meant for extended wear in body piercings, and should NEVER be worn in fresh or unhealed piercings - the silver will tarnish, and the tarnish can be deposited into your skin which causes it to turn gray or black. Silver can also cause allergic reactions for those who have nickel allergies. So it's okay to wear for a special occasion in a healed piercing, but has lots of nasty side effects if left in too long. As for the surgical steel: not all SS body jewelry is created equal! Lots of cheap steel body jewelry is made out of 316L Stainless steel, which is the minimum requirement for steel worn in healing/fresh piercings. Some people can wear this type of steel, but it can (and does) irritate and cause allergic reactions for others. Personally, I will only wear 316LVM ASTM F-138 Implant Grade Steel, which is the same type of material that doctors use when they put pins and plates in your body during surgery. It is the highest quality steel you can get, and will usually cost a bit more, but as someone with sensitive skin I am not willing to risk getting an allergic reaction from sub-par jewelry. Also, implant-grade jewelry is most often INTERNALLY-THREADED, which means that the threads are concealed inside the jewelry and do not come in contact with your skin. EXTERNALLY-THREADED jewelry has the threads on the outside, and inserting it into your piercings is pretty much the equivalent of dragging a screw through your navel. Whatever grade of steel you decide to go with, make sure the threads are on the inside!

Q:Coating on Steel Wool?
spun steel fibers have a microscopic coating of oil to prevent them from rusting. Rusting steel wool wouldn't sell very well. I would think that removing this oil could be accomplished with any good degreaser, like brake cleaner or the like. However, I've never tried this before. In science class they perform experiments by removing the oil with vinegar. After wringing out the steel wool pad, it is wrapped around a thermometer and placed in a sealed jar. After a few minutes the temperature rises because of the chemical reaction that takes place when four atoms of iron react with three atoms of oxygen and create two atoms of iron oxide - RUST! You can unwittingly recreate this experiment by using steel wool in the process of removing one or more layers of finish from a piece of furniture Hope this helps
Q:Is Steel a Pure Substance or a Mixture?
Scott, there are 3 types of materials: elements, compounds, and mixtures. Compounds are covalently bonded elements. Compounds and elements are both considered 'pure' substances. Mixtures are not bonded in any fashion. So a steel mixture can have varying amounts of iron, carbon, silica,molybdenum, etc., giving the steel the desired properties (strength, rigidity, rust resistance, etc.).
Q:Superman man of steel?
Faster than a Speeding bullet too!! They are just expressions/nicknames. Obviously he's faster than a speeding bullet, he can run from Kansas to Mexico and back and you wouldn't even know it. If you want it literally, just call him Superman, or extremely tough and fast man.
