What Are Some Unknown Facts About Steel

When it comes to metals, there is more than meets the eye. Be it determining strength or discovering the rarest metals known to humanity, you will find a wealth of information in today’s blog. This includes their strength, testing methods, and many other interesting facts about the rarest and strongest metals on Earth.

Understanding Metal Strength

The strength of a metal plays a huge role in its yield strength, tensile strength, ductility, and more. The yield strength of a metal is the stress at which plastic deformation begins. This is important as it shows how much stress the metal can handle before it completely deforms. For some metals, the yield strength is higher than the tensile strength. This is the maximum stress that the metal can handle before it completely breaks. This is because the yield strength refers to only plastic deformation while the tensile strength comprises of both plastic and elastic deformation.

Some of the strongest metals have very high yield strengths but can also be brittle. This means that they break easily if not used properly. One such example is cast iron. Though cast iron has very high yield strength, it is susceptible to break if it is hit or bent too abruptly.

Another important factor of metal strength is ductility. Ductility is a way on how easily a metal can be warped without breaking. Some metals like copper are very ductile and can be drawn into thin wires without breaking. Other metals like steel are less ductile and can break before drawn into wire.

There are many ways to test the strength of metals. One such method is tension testing where a metal sample is pulled till it breaks. This test measures the maximum stress that the metal can handle before breaking. However, this test does not provide any information about how much deformation the metal can handle before breaking.

The Strongest Metal in the world

Steels, alloys of iron, and other metals are harder than one type of metal alone. Alloys are a combination of metals that produce an even stronger material. Here are some of the strongest metals in the world:

  1. Carbon Steels: Carbon steels contain up to 2.1% by weight. They are further categorized into low-carbon steels, medium-carbon steels, high-carbon steels, and ultra-high carbon steels. The carbon gives the steel its hardness and strength.
  2. Maraging Steels: Maraging steels are iron alloys with a high percentage of nickel (18% to 25%), cobalt (5% to 8%), and molybdenum (0.2% to 0.4%). These steels feature a very high strength-to-weight ratio that makes them ideal for use in aerospace and military applications.
  3. Stainless Steel: Stainless steel is an alloy of iron, chromium, and other metals. It is highly resistant to corrosion and offers a high strength-to-weight ratio.
  4. Alloyed cobalt and tungsten: Cobalt is a tough, shiny metal that is used in alloys with other metals like iron, nickel, and chromium. Tungsten is a hard, breakable metal with a high melting point. It is used in alloys with other metals, such as steel to create a more sturdy material.
  5. Superalloys: Superalloys are iron-based alloys that contain high percentages of nickel (10% to 30%), chromium (5% to 20%) and cobalt (2% to 10%). They are resistant to corrosion and have high strength-to-weight ratios.

There are many other metals that display high levels of strength but the above are the strongest metals in the world.

The Rarest Metal in the World

Ever heard of rhodium? It is the rarest metal globally, with only about 9 metric tons worldwide. That’s why it’s one of the most expensive metals costing over $22,000 per kilogram.

Rhodium is a silvery-white metal that is corrosion-resistant and has high reflectivity. It is used for plating other metals giving it a shiny, reflective finish. Rhodium is also used in catalytic converters that reduce harmful emissions from vehicles.

Different Types of Metal Strength

There are many factors to consider while choosing a material for a specific purpose, but one of the most important factors is the metal’s strength. Different metals carry different strengths and some are better than others.

  1. Compressive strength – to measure how much resistance a metal has to be squeezed together. Some metals are very strong in compression while others are not.
  2. Tensile strength – to measure how much strength it takes to pull a metal apart. Some metals have strong tension, while some do not.
  3. Yield strength – to measure how well a metal resists warp. Some metals are very strong while others are not.
  4. Impact strength – to measure a metal’s ability to resist sudden force or impact without breaking. Some metals are very strong while others are not.


Metal is more interesting than you think. It has been around for more than 6,000 years and has been playing a vital role in history. For instance, did you know they were used to make the first coins? Apart from that, they are used in many industrial, commercial, and residential projects. If you are looking for steel industries in Dubai, then we at Al Baraq Steel Works are there for you.
