What are the properties of steel?


Steel is a material widely used in buildings and infrastructure, automotive, and equipment manufacturing. It is an alloy of iron and carbon, and the carbon ranges up to 2%. This is to improve strength and durability. 



What are common Steel applications? 

The world production of steel is about 1800 million tons of steel every year. That is equivalent to 180,000 Eiffel Towers in one year, according to The World Counts. The most common applications for steel are building and infrastructure, mechanical equipment, automotive, transportation, and metal products. 


 What are the properties of steel?

Alloys are usually stronger than pure metals, like iron. Below are seven properties of steel to consider. 

What is Tensile Strength?

Tensile strength is the maximum stress that material can stand before coming deformed. This test is done by stretching the material until it breaks. 

What is Ductility?

Ductility is a measure of the material's ability to deform (stretch) under tensile stress. This property is critical in the automotive industry. Automotive is one of the biggest consumers of steel. A car body needs to have flexibility, bending, and crumbling on impact to protect the occupants. 

What is Malleability?

Malleability is a property of a metal that defines its ability to be pressed, hammered, and rolled without the risk of breaking. Malleable steel is deformed under compression, creating variable thicknesses.

What is Durability?

Is this material going to withstand long-lasting wear and tear? 

Durability tests the hardness of the alloy and its ability to resist strain. 


What is a hardness scale? 

 There are two hardness scales, Rockwell or Brinell. This measures the wear resistance of the material and the machinability. 


What is Conductivity?

Conductivity is the property of steel that allows it to carry an electrical current. This test is often used for material that will be used as cookware and wiring. 


What is Luster? 

Luster is based on appearance, showing a grey – blueish outer surface. 


What is Rust Resistance? 

Zinc help prevent corrosion. The zinc reacts with oxygen when exposed to the atmosphere, forming a zinc oxide that reacts with carbon dioxide to form zinc carbonate. It stops further corrosion in many circumstances, protecting steel from the elements.
