Q:What's a steel guitar?
Different okorder.com/. If you just like the sound, take a serious look into slide guitar, not the same, but seriously tasty.
Q:Does mild steel have a high carbon content?
High carbon steel is much harder than iron. In fact, steel -is- iron with carbon in it. Mild steel has a very low carbon content and is much softer. High carbon steel is much stronger after heat treatment. However, about 2% carbon, it is considered cast iron. Mild steel contains about 0.16% to 0.29% carbon content. It has a relatively low strength but is highly malleable.
Q:Is 30CrNiMo8 a kind of high alloy STEEL?
It is a high alloy steel. Look at all the elements in it's name for it's composition: 30% Chromium and Nickel 8% Molybdenum Sounds like a very tough stainless tool steel for cutting rock or something. Chromium and nickel arre the two elements they use to make stainless steel and molybdenum is used to make steel very hard and wear resistant
Q:Questions about Steel. Please Help?
Steel is an alloy composed mainly of iron and carbon, but almost always contain small and various amounts of other elements. So all of these questions will have a range of answers. For example, the density of steel is between 0.280 and 0.291 pounds/cubic inch. The melting point for mild steel is around 2400F (1300C), but can be much higher, as in stainless steel which is 2800F because it contains a minimum of 11% chromium. Wiki has a legitimate definition.
Q:Damascus steel sword blades question,?
Folded Damascus Steel
Q:desnity of steel?
First you have to convert the coefficient of linear expansion to a coefficient of volumetric expansion. Multiply the coefficient of linear expansion by 3: Coefficient of expansion of steel,β:12E-6/°K x 3 = 36E-6/°K Difference in temperature: 480°K ΔV = VoβΔT ΔV = Vo x (0.000036) x 480 ΔV = 1m³ x 0.017 ΔV = 0.017m³ Originally, the steel was at 7800 kg/m³ Now, the steel was at 7800 kg/ 1.017m³, or 7670 kg/m³ Change in density = 7670 - 7800 = -130kg/m³
Q:Decorating stainless steel refrigerators?
I am a designer and have had to work with this issue in families where children's artwork is proudly displayed. You can frame a piece of sheet metal and hang on a wall in the kitchen. The website had step-by-step instructions:
