Density of Steel

Steel is like air, it's everywhere: from bridges to fridges and from washing machines to canteens. Steel is mostly composed of iron and carbon. It contains small amounts of manganese and even smaller amounts of silicon, phosphorous, oxygen, sulfur, and other elements.

Density is one of the numerous properties of steel. It is calculated by dividing the mass by the volume. Steel comes in many different forms. Their densities differ by type see below.Density are mentioned with in bracket

1.Steel, tool (7.715)
2.Wrought Iron (7.75)
3.Carbon Tool Steel (7.82)
4.Steel, cold-drawn (7.83)
5.Carbon Steel (7.84)
6.Steel, C1020, HR (7.85)
7.Pure Iron (7.86)
8.Soft Steel (0.06% C) (7.87)
9.Stainless Steel, 304 (8.03)
10.Stainless 18Cr-8Ni (8.03)

Unit Weight of Building Materials

During Construction we may need weights of building material like brick, different type of concretes and Charcol etc.

This is rare collection and will be useful to construction engineers

Short Cut Key



When a situation may arise your mouse is no longer functioning, or you're working with a computer with no mouse support. Shortcut keys help provide an easier and usually quicker method of navigating and using computer and it will increase your productivity. Some of the commonly used keys you will need to use to navigate MS Word  and MS Excel are here.

Mass Chart

This is continuation with my previous post Specific Gravity

The mass of over 30 different metals and alloys are listed below. While the data is useful for design, individual samples will differ. Impurities will often have an influence.

Specific Gravity

As you well aware that all materials having individual properties and weights based on the density. How we can compare the different materials in a same platform.

Pure water was chosen as the 'base line' for specific gravity and given the value of 1. The specific gravity of all other materials are compared to water as a fraction heavier or lighter density.

For example, Copper has a specific gravity (sg) of 8.93 (8930 kg/cu.m)

One handy metric link between units to remember is that 1 Litre [1000cc] of pure water weighs 1 kilogram.Equally, 1 milliliter of pure water has a mass of 1 gram or 1mL = 1g.

As specific gravity is just a comparison, it can be applied across any units.
Specific gravity is the same number as density but without any units (adimensional).

Weight Calculation for Other Metals

In continuation with my previous post let us see how to calculate the weights othar than steel.

Basic formula for any material calculation is

Area in Square Meter multiple by Thickness and Multiple by Specific gravity of particular material

Weight = Length X Width X Thickness X Specific Gravity of material

UOM  for Length & Width is Meter, For Thickness is Milli Meter

What is mean by Specific Gravity will see in my next post
