There are five different classes of steel, and many more types, all of which undergo a phase change at diffent temperatures. It mostly depends on the carbon content. The higher the carbon content (upper limit is approx. 2.1%), the higher the melting point.

When molten rock cools and hardens is a physical change or chemical change?
When molten rock cools and hardens, it is a physical change because the composition of the rock remains the same. The change in state from liquid to solid does not alter the chemical makeup of the rock.
What Materials can contain molten steel?
Molten steel can be contained in materials such as refractory bricks, clay graphite crucibles, and ceramic-lined ladles. These materials are designed to withstand high temperatures and prevent the steel from interacting with their structure.
What layer of the Earth is made of solid rock and squish molten rock?
the crust is made up of solid rock and mantle is made up of molten rocks
Is melting steel a chemical or physical change?
Melting steel is a physical change because only its physical state is altered, going from a solid to a liquid, without changing its chemical composition.
What physical state is steel at room temperature?
Steel is not an element it is a metallic alloy containing iron, carbon and other additives. At standard temperature and pressure it is a solid.
When molten steel becomes solid is energy absorbed or released by the steel?
Energy is released.
When molten solid becomes a solid is energy absorbed or released by the steel?
Energy is released.
What is the only difference between liquid or molten steel and solid steel?
Energy. The atoms in solid steel are moving more slowly than the atoms in liquid steel.
Is Pouring molten gold in a mold a physical or chemical change?
Pouring molten gold in a mold is a physical change because it involves a change in state from liquid to solid without altering the chemical composition of the gold.
What is the shape of solid steel?
Solid steel can be any shape that is required by the customer. In a molten state it can be poured into moulds at the foundry. White hot, it can be put through rollers to produce girders, or rolled into flat sheets, and trimmed to size under presses, and so on.
What is the mantle's materials?
It's very high temperature down in mantle so it resulting a solid rock to change into "molten" state. The molten material in the mantle is magma.
Could you use molten in a sentence?
Molten: The boy poured molten steel down his own throat. :)
Is the earth solid or liquid?
The asthenosphere is partially molten. It is about 5% molten.
HOW MOLTEN CHANGS INTO A SOLID?
It turns to a solid when it cools down
What is the antonym of molten?
An antonym would be frozen or solid.
When molten rock cools and hardens is a physical change or chemical change?
When molten rock cools and hardens, it is a physical change because the composition of the rock remains the same. The change in state from liquid to solid does not alter the chemical makeup of the rock.
Is the Earth's asthenospere solid or liquid?
The asthenosphere is partially molten. It is about 5% molten.
