All things being equal, increasing the carbon content decreases the melting point. However, the melting point of carbon steel (steel that has a carbon content below about 2%) is dependent on its total alloy composition. Other compositional elements such as manganese, copper, chrome, silicon, etc. are always present to some degree in low carbon steel melted from recycled scrap material.
For a binary carbon - iron system, the liquidus temperature begins at approximately, 2802 degrees Fahrenheit at 0% carbon and decreases to 2097° F at 4.3%.

How does melting point change as the water content of rocks increases?
As the water content of rocks increases, the melting point typically decreases. This is because the presence of water lowers the melting point of minerals in the rocks by acting as a flux that promotes melting. The addition of water creates a eutectic point where the rock will begin to melt at a lower temperature.
Does carbon have high melting point?
it has a low melting point
What happens to the melting point of the alkali metals as the atom increase in size?
As we move down the group, the melting point decreases.
Which trend decreases for metals down a group?
Melting Point
Why melting point decreases?
The melting point of a substance decreases when the intermolecular forces between its particles are weakened. This can happen due to factors such as an increase in molecular weight, the presence of impurities, or changes in the crystal lattice structure. As the strength of intermolecular forces decreases, less energy is required to overcome them, resulting in a lower melting point.
