The issues of measurement in terms of engineering are based on a scientific discipline called metrology [10].
However, this can be difficult because the innovative environment is not prepared to absorb advanced innovative technologies.
The condition can be stable, resulting from the features of the manufactured goods that are assumed not to require advanced research.

In machine components, a material that has hard and ductile properties is also needed, with this problem, of course, it is necessary to have material engineering to improve the mechanical properties of steel in order to obtain good quality.
Introduction The development of the manufacturing industry is currently advancing along with the times and technology.
In machine problem, of course, it is necessary to have material engineering to improve the mechanical properties of steel in order to obtain good quality.
Heat treatments that are often used to modify the microstructure and mechanical properties of engineering materials, especially steel is annealing, normalizing, hardening, and tempering [9].
