What is the unit weight of steel?

Answer 1

Steel is very strong. Our society is built of concrete and steel. The world as we know it would not exist without steel. Are there any military aircraft carriers that are not built of steel? But there are some lighter materials out there. What that means is that if you use aluminum to make, say, a seatpost for a bicycle, you'll have to make a thicker one out of aluminum to make it as strong as a steel one, but the aluminum one will be lighter while being as strong as the steel one. There are always trade offs when designing and engineering things and considering what metal to use.

Think about the bottom bracket on a bike with a 3-piece crank set. The axle is steel, or maybe titanium (same strength, but less weight - and more $'s!). Loads are so high here that this critical component is not made of aluminum 'cause it isn't tough enough to handle the stresses put on the part. And steel is the metal of choice for ball and roller bearings, particularly ones that take lots of abuse. Ceramics and carbide are harder, but they're more brittle, and can shatter under severe loading. It is most unusual to see bearings made out of something other than steel.

There are a couple of ways of measuring the strength of a metal, but the numbers don't make sense unless you compare one metal to another. Additionally, steel comes in many different alloy forms, and their characteristics will vary. Throw in the different techniques used to harden or otherwise heat treat the steel and you'll be here all day talking about how strong steel is. Yield strength and tensile strength of steel are, in general, pretty high, though. Steel is tough and strong.

Answer 2

How can we answer this question if you do not tell us the size of the piece? Perhaps you are asking for the weight densityor mass density of steel, which has already been answered here on WikiAnswers.

Answer 3

Carbon steel's density is approximately 7.85 g/cm^3. Not knowing which particular unit you want, or which particular type of steel to which you're referring, that's about as specific as one can get.

Answer 4

That depends on the quantity and the iron to carbon ratio.

use 7850 kilograms per cubic metre.

Answer 5

The weight of steel is dependent on the amount.

Answer 6

unit weight of steel is 490 lbs/cft

or 7800 kg/cum

Answer 7

Somewhere between 7480 kg/m3 and 8000 kg/m3. (Density: 7.48 - 8)
