Q:Steel Garage...........!!?
Maintaining Your Steel Garage: # Clean your garage doors with a mild detergent using a soft car brush four times a year. # Clean the doors whenever they wash you car (washing your garage doors regularly will reduce the build up of corrosive elements) #Avoid using any abrasive cleaners or corrosive chemicals on or around your garage doors. # Avoid using salt near the garage door as it may corrode the door elements / hardware. Or you can paint your steel garage: #Step 1 Clean the door using a low-pressure sprayer. Combine 5 gallons of warm water and 1 cup of low-phosphate detergent to clean the surface. Rinse well and dry the surface. #Step 2 Lightly sand and smooth the scratches which do not go through to the metal substrate. Dust off sand residue. For a door with a baked on finish, use a powdered cleanser (diluted with water) and a soft brush to rough up the surface for better paint adhesion; do not use sand paper. Rinse with water and allow it to dry. #Step 3 Apply primer to areas where scratches permeate to the metal substrate to avoid future rusting or corrosion. Allow it to dry. #Step 4 Paint the door with an even coat of latex exterior house paint. If your steel garage has a dent check out the site(the last source link at the bottom)
Q:Will carbon steel knives stick to a magnetic knife strip?
Carbon steel knives will stick to a magnet. Stainless steel may not.
Q:What steel is the most magnetic?
That is a part of engineering materials, it has a mixture of materials that has a good magnetic properties when they are combined like silicon and manganese etc.
Q:Why is steel a stiff material?
Steel is NOT stiff. In fact it is worldly accepted metals (steel is a metal) are not rigid in mechanical terms, and rigid means stiff. Steel easy to shape, but is strong and therefore hard to break. Thermosetting polymers (hard plastic) which is stiff, is in fact easy to break (weak) and also hard to reshape without changing its state (solid to liquid). Whoever told you steel is stiff is wrong and possible meant steel is strong, or you misheard/misunderstood.
Q:how to repair rusted steel concret?
The rust needs to be removed by what ever means works best for your situation.. Often a twisted wire wheel on a 4 1/2 angle grinder works quickly... a hand wire brush may work well for you, or just plain sandpaper and a LOT of elbow grease (hard work) will remove the rust. From there, a coat of primer paint made for steel. Any hardware store in your area would have such a primer, in quart cans or spray cans. Once that is dry (a good 24 hours for most formulations), you can spray or brush paint the beam most any color you wish.. I've had very good luck with acrylic enamel paints for such projects.. IF your steel is badly pitted, you should consider getting it inspected to insure it will still hold up or support what ever it was installed to do. If you want a smooth finish, once the rust removal is done, you can fill in the dips and pock marks with an auto body filler (Bondo is one brand name)... It comes in 2 parts (the main filler and a hardener) that are mixed well and used to fill in the holes and divits with a plastic spreader.. Once hard (in a few minutes with most brands of filler), sanding with sandpaper and a sanding block will smooth out the finish very nicely. From there, the same primer mentioned above and paint will finish up your project... Hope this helps some... Good Luck!
Q:Long term effects of steel on skin?
Stainless steel contains both nickel and chromium. These two alloys are responsible for most of contact dermatitis in people. Some of my co-workers making steel had such bad reactions to chromium that they had to quit their jobs. Their skin was always inflamed. People don't react to finished stainless steel the same way because the alloys are bonded tightly in the heat treating process. But if you are grinding it and getting the dust on your skin, you could get a contact dermatitis if you are sensitive. I don't think it would absorb into your blood stream or do any long term damage to your skin. If you do get a reaction, you would have to cease your exposure or in a worse case scenario risk getting a body wide reaction like my coworkers. I would not worry about any exposure making rings out of stainless steel. After all, stainless steel is used in sugical implants and most people are fine.
Q:Galvanized Steel Poisoning?
i have a dog with a galvanized chain on her neck ''for looks'' can she get even the slightest harmful effect from it being on her 24/7?
Q:What Metal is around 256% stronger than steel?
Depending on carbon content, alloy content and heat treatment, steel can have almost any yield strength you want it to. It can be as low as 250 MPa or as high as 1700 MPa. That's more than your 256% difference right there. So maybe the answer should be itself.
Q:how simple is it to recycle steel?
You mini-mills operate between 150,000-2million tons of steel per year. If that is the size you were thinking about... you are in business. But since you are asking on Yahoo Answers where no serious industrialist would EVER ask a question like this, I can only assume that your ideas of small are completely incompatible with reality.
Q:What is the energy used in making steel?
Making steel is very energy intensive. Mining the raw ore requires a lot of machinery that uses fuel or electricity . Transporting the ore requires a lot of fuel. Refining not only uses a lot of electricity but coal is added to change the iron ore into steel.
