What is the hardest metal on earth?

Answer: There will always be an oscillation between the strongest and the hardest metal. Chromium is the hardest metal, and Tungsten is the strongest metal on the earth. Also, Chromium is the main element that is used in the production of stainless steel.

Chromium (Cr) is one of the most significant elements, with 24 as its atomic number. The element is well known for its shiny silver colour, which has extreme hardness and resistance to chemicals. The element has a hardness scale of 8.5 and 9 in the Mohs reading. Due to its high tensile strength, it is known to be the hardest element on the earth. Besides carbon and boron, Chromium is considered the hardest element.
