Q:Whats better, 1045, or 440 stainless steel?
1045 stainless is better
Q:what is brass and steel used for and why?
By instruments do you mean musical instruments? Brass is used for musical instruments because it's strong but very malleable. It's easy to hammer and roll into sheets, or form into tubes and complex shapes. It's easy to work with using hand tools. It's also very corrosion resistant and polishes very well. It has an attractive gold-like color. It also has some effect on sound, though the shape and design of an instrument is much more important to the sound than the material that's used. Apart from musical instruments, brass is used for items that need to be both durable, easy to manufacture, and resistant to the elements. For example plumbing items like valves and screw couplings.brass is a lot easier to cut with machine tools than steel. It's also traditionally used for hardware on doors and cabinets because of it's color, low friction properties, and corrosion resistance. Brass also is toxic to bacteria, and so brass doorknobs disinfect themselves after about 9 hours. Steel is very strong and very cheap. Steel is basically iron with a small amount of carbon added which makes it much stronger. Iron is the fourth most common element in the earth's crust, after oxygen, silicon, and aluminum. Brass being a mixture (an alloy) of copper and zinc, with other metals sometimes added. Copper and zinc are the 27'th and 26'th most common elements. Therefore, it make sense that brass is much more expensive than steel. Steel is used for too many things to be listed. The use of steel technology has impacts on almost every aspect of modern life. Nearly all of the man-made objects you touch on a regular basis were made using steel tools and steel machinery.
Q:The difference between aluminized color steel roll and ordinary color steel roll
Ordinary color steel roll is a composite material, also known as color coated steel plate, is used in the continuous production line on the production line after surface degreasing, phosphating and other chemical coating treatment, painted with organic coatings, made by baking products. Both steel and organic materials are a little bit different. Both the mechanical strength of steel plate and easy molding performance, but also organic materials, good decoration, corrosion resistance.
Q:what steel anodizes well?
Steel doesn't anodize in the sense that aluminum and some other metals do. However, it can be heat-colored. The trick is to clean the surface first (it must be oxide free), then heat gently until the colors appear. These are called temper colors in steel. They are due to a thin adherent layer of oxide that forms and thickens as temperature is increased. They are quite temperature dependent. As the steel is heated, the first color to appear is pale yellow. This will progress through darker yellows, browns, purples, and blues as the temperature rises. Above blue, the oxide becomes the gray/black color you are apparently getting - this is the result of heating too fast and too hot. See the chart at the site below for colors in plain carbon steel. Note that the temperatures are pretty low - It all starts around 400 F and if you go above 600 F the show's all over.
Q:How is steel manufactured?
The steel consists of ( Iron ) and another matter... but the popular one is iron+carbon / iron+silver - When iron is smelted from its ore by commercial processes, it contains more carbon than is desirable. To become steel, it must be melted and reprocessed to reduce the carbon to the correct amount, at which point other elements can be added. This liquid is then continuously cast into long slabs or cast into ingots. Approximately 96% of steel is continuously cast, while only 4% is produced as cast steel ingots. The ingots are then heated in a soaking pit and hot rolled into slabs, blooms, or billets. Slabs are hot or cold rolled into sheet metal or plates. Billets are hot or cold rolled into bars, rods, and wire. Blooms are hot or cold rolled into structural steel, such as I-beams and rails. In modern foundries these processes often occur in one assembly line, with ore coming in and finished steel coming out. Sometimes after a steel's final rolling it is heat treated for strength, however this is relatively rare.

Q:Can I shoot steel shot out of my Remington 870 express?
If it says on the barrel that it will chamber 3 shells, then it is a MAGNUM barrel. The gun receiver should also have an M suffix at the end of its serial number.
Q:So i got caught steeling?
Steeling? What's that? Did you take a piece of steel and weld it? I am confused?
Q:what is the density of stainless steel?
This Site Might Help You. RE: what is the density of stainless steel? density of mild steel (MS) is 7850 KG per metre cube , but i want to know the density of stainless steel
