Q:Movies- Conan: What is the riddle of steel?
Doom answers this question by explaining to Conan that the true strength of steel is in the hand that wields it – in other words, it is the resolve and commitment we bring to a task, not the quality or quantity of tools we use in performing it, that is the most important factor in determining success
Q:What is INOX Steel?
Inox Steel
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:Which one steel or metal?
Metal includes steel, as well as thousands of other metals and alloys. In other words, steel IS a metal. So your question is meaningless, sorry.
Q:What is Mild Steel? Is it the same as Seamless Steel?
I am a Blacksmith,mild Steel is what I use every Day,I make Ornamental Ironworks,like Handrails,Gate,Candle holders,all kind of things,most things are made from mild Steel,even Buildings,Doors,and so on.No risk of buying it.Special Steel is just for Special Applications.
Q:What's the difference between hot rolled coil and hot-rolled carbon thin steel coil?
The difference between hot rolled primary and hot-rolled carbon thin steel coils is that they include carbon steel rolls and low alloy steel coils.
Q:.308 steel cased ammo in my remington 7400?
Kudos to NXile for his/her post. Ironically, I recently posted a similar answer in this forum and got many thumbs down. The problem with the non-expansion of steel cased ammo is not limited to the blow-back and soot build-up inside the action. The other problem is that your Remington 7400 was engineered at the Remington factory as a sporting firearm that uses brass cased sporting ammunition. When you switch to the steel cased ammo, the casing doesn't have a chance to grab at the walls of the chamber to slow it down. The result is heavier recoil on the action of the gun. Over time, you will break something. Also, I don't like the idea of steel rubbing against steel inside the chamber area of a gun. I know sure sure I won't use steel cleaning rods or brushes to clean the barrel of a rifle. So why would I want to chance shooting steel cased ammo? The only stuff I will shoot steel cased ammo out of are the junky SKS and AK style rifles that I don't care about. Anything with real value...and I only use brass ammo with non-corrosive priming.
Q:What is purpose of providing steel in compression zone in Doubly reinforced beam ?
There are several reasons to add compression steel. Keep in mind, supported steel (meaning it can't buckle) resists compression as well. Compression steel helps reduce long term deflections. Concrete creeps under sustained loads. Steel lessens the compression, meaning less sustained compressive stress to cause creep deflection. It makes members more ductile. Since the steel takes some of the compressive stress, the compression block depth is reduced, increasing the strain in the tension steel at failure, resulting in more ductile behavior (the moment at first yield remains largely the same with compression steel added, but the increase in capacity after yield is significant). Compression steel insures that the tension steel yields before the concrete crushes, meaning it helps change the failure mode to tension controlled. It makes beams easier to construct. With bars in the top and bottom, you have longitudinal reinforcement in all 4 corners of the shear stirrups to keep them in place when pouring the concrete. Also, for continuous members, its often easier to run your negative moment steel the full length of the beam rather than trying to cut it off in the positive moment regions. Serviceability concerns. You're going to end up putting steel in that region anyway to for temperature and shrinkage.
Q:when was steel first made?
No, the iron age was just iron. It was smelted down in open fires where temperatures can vary. There was a problem of not always being able to cook out all the impurities from the ore, which led to inconsistent strengths in finished products. People first discovered the properties and advantages of steel when charcoal (carbon) was added to smelted iron. I don't know when the first steel was made. But it must have been a more expensive process because it didn't appear in household products until around 1800. But I'm not sure on that.
Q:How can I tell the difference between different knife steels?
If your question implies how to tell the differences just by looking at the actual knife then I'd say there is no real way to do that. Just about all high carbon steel's look alike. You should be able to tell the difference between a stainless steel, but which one is anybodies guess, and a carbon steel however.
