Responses

  1. thank for the sharing bro, and waiting for the next quiz

  2. apa kabar mr.nov
    di mana saya bisa ambil kursus PMDS?

  3. more quiz on CSWIP 3.1 is expected.
    I am also waiting for your article on SS and DSS as these steels are used as well in fabrication especially their metallurgical characters.
