At the barest minimum, Iron and traces of Carbon.
Steel contains Iron and Carbon. Various steels contain different compounds of the two plus other material to create different alloys.
The two elements that make up steel are mainly carbon and iron.
Iron and copper, steel and bronze are not elements.
Two metals commonly used to form alloys are iron and nickel. When combined, these two metals create a popular alloy known as stainless steel, which is highly resistant to corrosion and heat.
Alloy steel typically contains iron as the base element along with a varying mixture of carbon for strength and other alloying elements such as manganese, chromium, or nickel to enhance specific properties like hardness, corrosion resistance, or strength.
Steel is primarily made up of iron atoms with trace amounts of other elements such as carbon, manganese, and sometimes silicon. Generally, there are one or two types of atoms in a steel can, depending on the specific alloy composition used in its production.
Iron is an element in its own right. So there are no two elements that make iron. However, Steel is an alloy of iron and carbon. Iron and Carbon are tweo different elements. So steel contains two different elements.
Two elements that can form a crystal together are carbon and oxygen, which combine to form the mineral calcite.
When two of the same elements are bonded together, it is called a diatomic molecule.
When two or more elements bond together they form a compound.
When two or more elements bond together they form a compound.
After a chemical reaction two elements form a chemical compound.
