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.

What element causes the known as cold shortness in steel?
phosphorus
The production of iron and steel came from a branch of science called metallurgy?
That's true
What are the characteristics of metallurgy?
history of metal metallurgy
Branches of metallurgy?
Metallurgy is broadly divided into following branches : 1. Mechanical Metallurgy 2. Physical Metallurgy 3. Extractive Metallurgy These are the basic divisions and these branches are further divided into various sub categories.
Which has higher density cold steel or hot steel?
When steel gets hot, it gets slightly larger due to thermal expansion. Since the mass stays the same, and density = mass/volume, it gets (very, very slightly) less dense. So cold steel is more dense than hot steel.
What is red-shortness in steel?
is the steel which breaks as it's heated to red hot
How do you control hot shortness?
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
Did the knowledge of steel metallurgy begin with the Hittites?
No, the knowledge of steel metallurgy predates the Hittites. The Hittites were skilled metalworkers and played a role in advancing metallurgy, but the origins of steel production can be traced back to ancient civilizations such as the Mesopotamians and Egyptians.

What is hot shortness?
Sulfur in steel is considered injurious except when added to enhance machinability. Sulfur readilly combines with iron to form a low melting iron sulphide. Sulfur causes hot shortness in steel unless sufficient manganese is added. Sulfur has a greater affinity for manganese than iron and forms manganese sulphide which has a meltin point above the hot rolling temperature of steel, which eliminates hot shortness. By hot shortness we mean that the steel will literally break apart during hot rolling resulting in a scrapped product
