Hello, this is DC, which is all about certifications that "design the sensibility of mechanical design."
In the case of juice & material, there is no need to memorize them separately because they are included in the KS standard PDF file.
However, you can apply the appropriate material among the materials listed in the public corporation standard house. In an ordinary test, it is enough to memorize three "GC250/SM45C/SC480"!
