Yes,steel grade SAE5140 or AISI 5140 can be heat treated.
It is important to heat treat in vacuum as otherwise lots of oxides form; after heat treat in vacuum oxides are removed, if part small enough, by use of an abrasive grit pad, such as Scothbrite A, and cleaned with acetone followed by isopropyl alcohol. If not protected, however, oxides will continue to form in air
Heat increases the potential energy and temperature of steel.
yes
Between 121-137 on the Brinell hardness scale - which is quite soft. The end parts are generally case-hardened before use to 60+ Rockwell "C".
what is the difference between product analysis and heat analysis
Definately spring steel can be heat treated and it has to be heat treated before it can be functioned as a spring. The common way to heat treat spring steel is by quenching and tempering.
You heat treat to improve the molecular structure of the steel. In the untreated state steel is very soft and is relatively easy to bend but when hardened the steel become very hard and brittle. The steel is so brittle after hardening that if say dropped on a concrete floor it may shatter. Tempering relieves some of this stress and makes the steel hard but not too hard.
5140 is a decimal in its own right. You do not need to do anything.
The standard material used in manufacturing the forks is AISI 5140 American standard and Chinese standard is 40Cr....enjoy
It will be at least 117,000 psi and as high as 290,000 psi - the range depends on the tempering temperature and heat treat

heat. the heat will make the steel more malleable and easier to work with
Yes. Steel has mobile electrons to conduct electricity and heat.
