iron
Yes. Various elements are added to steel to make it harder, or stainless, etc. Tungsten is typically added to iron to make harder steel, but there are other elements for this, also.
Iron and carbon.
The two elements that make up steel are mainly carbon and iron.
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.
No, steel is not an element. It is actually considered an alloy, and the elements iron and carbon are the basic ingredients for making steel. Certainly other elements can be added for different reasons, like chromium for the production of stainless steel. But it is iron and carbon that make steel.
Some are steel, some aluminum.
The four main elements in stainless steel are iron, chromium, nickel, and carbon. These elements interact to provide stainless steel with its unique properties such as corrosion resistance, strength, and durability.
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.
Many people use steel and stainless steel, perhaps stainless steel welding wire to make cheap resistance heating elements.
The main ingredient of steel is usually iron. Secondary ingredients usually include carbon, and smaller amounts of other elements, depending on the type of steel.
Steel is an alloy made primarily of iron and carbon, so it is not a pure element that can be listed on the periodic table. Instead, the elements that make up steel, such as iron and carbon, are listed individually on the periodic table.
Stainless Steel; all other choices are elements - stainless steel is a steel alloy (composite elements).
