it will start to change slowly after 20 degrees C. At 400 degrees C it will degrade quickly - almost linealy to 800 C where it will hve reached approx 10% of its yield strength.
Because high carbon steel has low fluidity & low carbon steel has high fluidity.
IRON
A 487 is a high strength low alloy steel. there is nothing such as a carbon steel .iron becomes steel only when carbon is added to it.steel itself is an alloy of iron and carbon.hence the term carbon steel is wrong it is just steel.
Carbon Steel is used upto 427 oC or upto 1100 oF.
Heat increases the potential energy and temperature of steel.
The melting point of steel goes down to a lower temperature when the proportion of carbon is increased. The steel becomes harder and is not as easy to weld as lower-carbon steel.
Steel is iron mixed with carbon, the amount of carbon changes the specifications of the steel (strength, elasticity,...)
Stainless steel is a steel-chromium alloy that is more resistant to corrosion than carbon-steel or other steel alloys. As with all steel, it strength depends on its grade; but overall the strength difference between carbon steel and stainless steel is negligible.
Because high carbon steel has low fluidity & low carbon steel has high fluidity.
IRON
The amount of carbon in iron metal determines the strength and type of steel.Steel with low carbon is called low carbon steel and carbon with medium carbon called medium carbon steel. It is called low carbon steel if the carbon content is around 2.5 % or less. Others may be called medium or high carbon steel like that used in Die Steel of cutting tools. Generally low carbon steel are preferred if welding is adopted.

Iron alone is a tough element with relatively low strength when compared to steel. Carbon is a brittle element. Through the addition of carbon, iron gains its strength.
At about 550° C (1,000° F) Steel is at 50% Strength and at about 800° C (1472° F) structural steel loses 90% of its strength
High carbon steel is a metal.The addition of carbon makes the steel harder after heat treatment.
304 strength ranges from 80,000 psi to 250,000 psi, depending on degree of cold work. Standard carbon steel strength is less than 80,000 psi.
There are thousands grades of low carbon steel in the world. The properties (tensile strength) depends of a lot of parameters such as product type, heat treatment, micro-alloying, dimensions of products, etc. Max possible tensile strength for low carbon steel is 1200 - 1400 MPa.
