Stainless Steel

Stainless steel is a specific alloy that has components of manganese, chromium, and steel. The addition of chromium and manganese to the steel gives it a corrosive resistant property, combined with a high yield strength. The yield strength of stainless steel is somewhere around 1550 MPA and it also has a tensile strength of approximately 1600 MPA. The alloy has high impact resistance and a medium Mohs score.

Carbon Steel

Carbon steel is an extremely common alloy of carbon and iron, which has been produced for centuries now. It scores very highly in all four strength categories, with a tensile strength of about 550 MPA and a yield strength of around 260 MPA. It has a Mohs score of about 6.0 and high impact resistance.

Steel/Iron/Nickel Alloys

There are different Steel-Iron-Nickel Alloys, which are made by combining carbon steel with nickel. The effect of this combination increases carbon steel’s already fairly high yield strength to somewhere around 420 MPA and its tensile strength to the neighborhood of around 460 MPA.

Titanium

Titanium is a naturally occurring element, so it’s not an alloy. It is stronger than most other metals like tungsten when it comes to tensile strength. It has one of the best tensile strength to density ratios of any metals. Titanium alloys tend to be very lightweight, and their strength in addition to this lightweight property makes them ideal for use in the aerospace industry. Titanium does tend to have a lower Mohs score though.

Titanium aluminide is an alloy created from vanadium, aluminum, and titanium. The combination of these three metals gives the alloy a tensile strength of about 880 MPA and a yield strength of approximately 800 MPA.

Tungsten

Tungsten is another naturally occurring element, much like titanium. Tungsten is known to have the highest tensile strength out of any known alloy, natural metal. That said, tungsten is also known for being brittle and easily shattering when impacted, compared to other metals. To compensate for this, tungsten is often combined with other metals like steel to create more robust alloys.

Tungsten Carbide is an example of an alloy of tungsten. The combination of carbon with tungsten makes it more versatile, with a yield strength of between 300 to 1000 MPA and a tensile strength of between 500 MPA to 1050 MPA. Tungsten carbide is frequently used in the creation of sharp-edged tools like circular saw blades and knives.

Iron

Iron is not only one of the strongest metals in the world, it also is fairly simple to collect and refine, making it the choice of metalworkers throughout much of history. Iron has been used to make many different tools and weapons, and frequently used to supplement other metals. Cast-iron has a Mohs score of around five, while it has a tensile strength of about 414 MPA and a yield strength of about 246 MPA.

Chromium

Chromium has a Mohs score of 9.0, meaning that it is arguably the hardest metal in the entire world. Chromium’s drawbacks are that it doesn’t have great tensile strength or yield strength compared to other metals, hence it is often used to supplement other metals and create more robust alloys, rather than being the only type of metal used in a project.

Inconel

Inconel is a superalloy constructed of chromium, nickel, and austenite. Inconel is known for maintaining its strength even in conditions of high temperature and extreme pressure, w
