Q:Why should I use stainless steel cookware?
Stainless steel has some benefits: 1) Dishwasher safe: my anodized aluminum pots are NOT dishwasher safe (my wife put one in and it lost its gun-metal gray finish - sad) 2) Conductivity: most stainless steel cookware has an aluminum (or copper) middle - this transfers the heat nicely - steel by itself does not conduct heat evenly. All Clad cookware refers to the fact that the aluminum within the cookware is clad in steel. 3) Aesthetics: stainless is pretty. Stainless is not anti-stick, so you'll have to use all your skills to avoid sticking. 1) Use oil or butter: heat your pan before oiling. Once to temp, add the oil/butter and wait for it to heat-through. THEN add your food - sticking should be minimized. 2) Move your food around a lot: once you add a piece of food that is likely to stick, move it shortly afterward. This will prevent the food from gluing itself to one spot in the pan - a crust will start to appear, and that will protect the food from sticking. 3) Love the fond: anti-stick pans don't have a good chance at fond development (fond is the stuff that sticks to the bottom of the pan, and is crucial to pan sauce creation). You should experiment with your cookware, or send it to me: I am wishing for some new cookware.
Q:Why can hot rolled coils be placed outside?
Because the stress of participation should be eliminated
Q:Will my damascus steel knife rust?
Damascus Steel Rust
Q:Steel and Graphite shafts?
if you are a good player they say steel shaft is better. more consistent. I prefer graphite its lighter and I can flip my wrists easier.
Q:what happen if carbon steel is exposed to an oxygen?
Assuming the steel isn't actually melted, two things will happen. First, a layer of iron(ii) oxide, FeO will slowly develop on the surface, getting thicker over time. This layer is usually poorly bonded to the metal surface, it tends to flake off, exposing fresh metal. This is known as mill scale, it's also known as wustite which is the mineral term. Second, the surface of the steel will become decarburized, essentially becoming pure iron, not steel. The depth of the decarburized layer depends on the temperature, time, and the diffusivity of carbon in the steel at the given temp. This has some implications to engineering, in hot-rolling or forging of steel shapes for example. It's often the case that the stress and strain in a material is greatest at or near the surface. Therefore the weakened, decarburized layer at the surface may have a much greater detrimental effect on the steel's performance than might be expected. In a more specific example, die and tool steels depend on their carbon content for their strength and wear resistance, Therefore if such steels are heated in an oxidzing atmosphere, wear resistance is totally destroyed: The thin decarburized iron layer will be extremely soft and malleable.
Q:Steel Case V.S. Brass Case ammo?
I think you answered the question correctly yourself. Yes. BRASS CASE IS BETTER. MUCH MUCH BETTER. Steel case is for the birds. Brass case feeds better in semi-autos as far as I can remember. High end guns all the way to cheapo's, the brass stuff is better. Ever notice how steel case cartridges almost always seem to have visible bulges in the cases right at the butt ends of the bullets? ? ? Not quite so with brass ammo. Cheap shots or expensive shots I prefer ammo in brass.
Q:Which is stronger - sterling silver or stainless steel?
Sterling is always best, but, in the 30's and 40's India also plated silver with brass overlay, believe it or not. They thought the look would be more attractive to tourist and more Indian traditional. Pieces marked India have been found to be 80% silver with brass overlay. Several times I have taken India marked pieces that looked brass to a metallurgist and found they are actually 80% silver with brass coatings. Like anything else, this is not always the case, either way, pieces marked and numbered will draw attention.
Q:What is the maximum width of galvanized steel strip, please? The galvanized coat is 275, and how long is one coil?
The length of the roll is related to its width and thickness, but not to the extent of the zinc layer.
Q:Iron heavier than steel?
Steel is iron, with other things added that strengthen it and/or make it less rust liable. So, in general, steel is stronger than iron. In so far as the density, that depends on the steel alloy. Some are higher than iron, some lower. Remember there are hundreds of different steel alloys. edit: but the density is still close to that of iron. density steel 7750 to 8050 kg/m³ density iron 7870 kg/m³
Q:What is the best brand of stainless steel sink?
Yes, it’s a good idea to look for the best brand of stainless steel sink as it is used in various purposes regularly. Top brand of stainless steel is naturally longer lasting and capable of bearing lot of pressure then normal stainless steel sink. You must see top brands as well as their prices before buying any.
