Q:Why is steel denser than wood?
A steel atom has more mass than wood becaue it has a larger number of protons and neutrons in it's nucleus. So steel packs more mass (more matter) into the same space as wood. Density is mass/volume. If you have a 1 cm cube of steel and a 1 cm cube of wood they are the same volume (1 cubic cm) but the steel has more matter in that volume and therefore is denser.
Q:Is blue steel stronger than stainless steel? i heard it is.?
Stainless steel requires less maintenance, but I've got a K-38 Combat Masterpiece from 1974. Back then SW used the real blueing process, and the blue steel looks like its a foot deep. Probably the best looking gun in the accumulation. Still new in the box, never fired. Its my Vietnam tribute gun, same one I carried as a Security Policeman in the Air Force from 1969-1971.
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:Ideas for Fantasy Culture: Steel Making?
Well, steel is just modified iron, so you're going to have to start with acquiring the iron first. For that, you're most likely going to be using some sort of underground mining somewhere - either they do that themselves, or they purchase the iron elsewhere. Assuming you're not dealing with meteoric iron (which is possible, but pretty uncommon), or iron sands (not likely in a woodland area), then unless you're dealing with a rocky outcropping with iron veins out in the open, I'm pretty sure there needs to be somebody doing some digging. That said, it doesn't need to be a full raping of the land scenario. A couple of minor mines, some small-scale smelting operations, and somebody knowing the secret of making steel, and it could give you small amounts of steel without making an ecological disaster.
Q:A question about steel.....?
As first answer says, if you look at the number of commercial steel alloys available and consider that any given alloy can be heat treated to a wide range of physical properties, there are thousands and thousands of potential combinations. Technically, steel is an alloy of Fe and C but there are Fe-C alloys that are called cast irons, not steel, and... there are lots of alloy steels which have significant amounts of other elements added like Cr, Ni, Nb, V, Mo, etc. Fe alloys that have a lot of Cr and or Ni added are called stainless steels and there are dozens of them and many of them can be heat treated to produce a wide range of properties. As far as the strongest or the weakest, you have to get really specific about exactly what you mean because some steels are designed for room temperature properties, some are designed for elevated temperature properties, some for static loads, some for impact loads, some for wear resistance, etc, etc.. Steels make up the largest family of metal alloys (by weight and by volume) that humans use. There are a number of reasons for this but the big reasons include: 1) there is a LOT of iron on earth 2) it is relatively cheap to produce 3) you can easily change the physical properties over a every wide range. As an example... you can take a piece of steel that is so brittle it will shatter if you drop it on the floor and heat treat it so you can bend it like a pretzel without cracking and then heat treat it again to make it very strong and tough (resistant to fracture).
Q:Is Damascus Steel Fake?
damascus steel it says is made from ore containing either tungsten or vanadium, although most tools I've seen are made from chrome vanadium, it wouldn't be hard in this day and age to get the proper material. Although it DOES say in wikipedia that apparently the technique died out a long time ago due to shortage of the ore. Then it talks about reproduction attempts. So theoretically, yes, it could be the deal deal. But it does refer at the bottom about damascend steel which is made with a different technique, you could be buying one of those. NEXT TIME JUST LOOK UP THE ARTICLE YOURSELF AND READ IT
Q:low density steel?
1. A method has been developed for magnetic phase analysis of Fermanal type alloys as-quenched and after aging. 2. The upper limit of alloying to ensure the optimal mechanical properties was determined more precisely for steel 9G28Yu9MVB. For rods aged at 550°C for 16 h the aluminum content should not exceed 9.2% and the carbon content 0.92%. 3. To ensure the optimal mechanical properties of the deformed metal it is necessary to obtain a fine-grained single-phase austenitic structure after quenching. The amount of hardening phase after quenching should not exceed 15–20% (saturation magnetization around 1600 G).
Q:Is T-304 Stainless Steel dependable?
Surprisingly any stainless steel is considered soft or tough metal. A hardness tester will bare this out. It resists work hardening which means you can bend it many more times than cold rolled or hot rolled steel before it will break. Your choice is a good one for your intended purpose.
Compression Ferrel connections are the best. for small diameter pipe and tubing. A local hardware shop can supply you with the necessary parts and pieces and can also give you a step by step procedure/self help brochure. This will also allow you to install any valve or t or blank in the piping system. The only tools required will be wrenchs and a tube/piping cutter for this type of installation. Brazing is accomplished by heating the base metal and then the rod. There are different types of brazing rod such as brass, bronze etc.. you will also need a can of flux to coat the rod or you can buy the rod pre-coated. If the seam is flat metal you can use the heat from the brazing tip to make the filler rod follow the direction you want. This also includes vertical such as on an auto body. I would suggest practicing this in a safe area. Always utilize a fire extinguisher, brazing goggles, welding gloves and wear a long sleeve shirt for your protection.
Q:Hardenability of steel?
Bit tricky to explain and I don't know muh about it but steel on its own has lost of gaps in it ( the molecular structure) and when carbon is added thos gaps are filled, I think of it like this: it is easier to punch through expanded polystyrene( with all the little balls) than unexpanded(just a lump of plastic) as the balls are not properly joined and have air pockets between them.
