The hot working of steel can easily be defined as " the mechanical working on steel after heating above the recrystallization temperature" e.g. forging, hot pressing, drawing etc.
No, a forge is not hot enough to actually melt steel. However it is hot enough to make steel pliable .
Yes, hot-rolled steel is magnetic. A few types of steel have limited magnetic properties, but hot rolling is a process by which steel is prepared in a shape for marketing. The hot rolling does not affect the ability of the steel to be attracted to a magnet.
The main reason of hot sortness is sulphur in steel. Therefore, answer of control of hot sortness is to control the sulphur in liquid steel before casting
is the steel which breaks as it's heated to red hot
Plate mill
This varies from material to material. Aluminum can be as low as 500 degrees by some specs while steel can approach 2000 degrees while hot working. You need to be more specific on the material being hot worked.
The term is used for character of steel, which become brittle at hot working temperature ie above 0.6 Tm (recrystallization temperature, where strain hardening is removed ) hot short hinders in hot working operation, often caused by the presence of sulphur in metal.
Red hot
When ur hot and ur working then it is hot working, if ur cold and ur working then it is cold working
If the liquid is hot,the spoon get heated because steel is an insulator

You can't use steel to make a hot water tank because steel can rust.
Hot Steel - 1940 was released on: USA: 24 May 1940
Yes, galvanized steel can get hot in the sun because it absorbs heat from sunlight.

Hot dipped galvanized steel can be welded and is available as HOT DIP GALVANIZED WELDED WIRE MESH. Galvanizing is a process where zinc is applied to steel to protect against corrosion. It is also used to give steel a bright finish.
