Q:Is the Bianchi Pista Steel bike good?
It will be fine as long as you don't use it for tricks.
Q:What brand steel tapes are of good quality?
Durable durable depends on your personal use frequency, the high frequency nature is easy to wear, resulting in scale. If you like fuzzy units if buying tape need verification it is best to buy the Great Wall Seiko goods, because the time to measure the number of verification inspection of steel tape, basically qualified rate of the Great Wall Seiko steel tape can reach one hundred percent.
Q:What grade of steel is best for a permanent magnet ?
The type of steel you require is Steel ( Iron + Carbon, mainly.),{many different types of steel } with a high Cobalt and Nickel content. These alloyed together give the best Permanent Magnets, mainly due to their own individual magnetic properties / characteristics being retained in the Alloy. All 3 metals can be magnetised by there own, but Cobalt is known to cause cancer. Nickel, is poisonous and can also cause sever Dermatitis and the destruction of skin tissue.But when alloyed together with Iron they are pretty harmless. Interesting thing is, All of these metals (in this case Elements) can share the same Mass Number ( 60 ). And yet are totally different in their other properties beside Magnetism. Cobalt - Samarium - alloys, create some of the worlds most powerful permanent magnets. And were used in medicine, But are now superseded by Neodymium magnets which are employed instead. Edit; What you could try is, mild steel which is widely available and easily found. . The steels mentioned above are pretty exclusive materials and I personally would not know how to test for their contents, of which they are made from. Soft Iron is good for making electro-magnets if you fancy a go at making one. .
Q:How to solve steel plate storage
According to the principle of "first in first out" to carry out the turnover, organize the logistics, reduce the large amount of moving plate, reasonable arrangement, easy to steel coil into the use of state.

Q:Different properties and uses of three types of steel?
Hi, Three Main Types of Steel: 1. Carbon Steel Used in making axes, swords, scissors,cutting tools, vehicle frames. Depends on the % of carbon used how soft the steel will be. 2. Stainless Steel Used in the making of crockery, wrist watches, kitchen utensils, cutlery and surgical equipment. Contains different 11% chromium and some % of nickel. 3. Alloy Steel. Used in making drilling parts, vehicle airplane parts. Stainless steel is also alloy steel but, alloy steel with % of other metals is classified separately.
Q:About hydrolics which one used in steel melting shop?
The correct spelling is hydraulics. I haven't heard the term steel melting shop you probably means a foundry or a steel mill The most obvious example i can think of is hydraulic-operated fork lifts. Hydraulic cylinders are used to lift the forks and to tilt them upwards or downwards. The valves are coneccted to levers next to the steering wheel. Hydraulic pressure is supplied by a hydraulic pump driven by a propane or diesel engine. In some forklift designs the wheels are also not connected directly to the engine, but driven by hydraulic motors. There are also a large variety of machines used in steel mills and metalworking companies to cut and shape metal parts. for example, press brakes, plate cutting shears, stamping presses, hole punch machines, drawing presses, etc. These types all operate in much the same basic way. They use a very large cylinder or group of cylinders to apply many tons of force to different kinds of metal working tools.
Q:Can fire resistant building materials burn hot enough to melt steel columns?
Steel loses strength as it is heated and will fail long before it melts. A mild steel that starts out at 100 degs F with an allowable stress level of 20,000 psi will be down to only about 2000 psi at 1000 degrees. As to fireproofing for steel. It doesn't have an unlimited life. In fact most has only a 2 to 4 hour rating and that is determined in ideal conditions in a laboratory. The idea is to give firefighters time to get everyone out of the buidling.
Q:What's the best dishwashing soap for stainless steel?
stainless steel does not work in a dish washer.Warm soapy water and dry straight away, they will last forever.
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!
