[Reproduction of Private Spring Preparatory School Lecture 35] Introduction to the JIS numbers, symbols, and chemical components (only carbon and manganese content) of three types of wire materials!
Today, let's take a closer look at the properties of wire rods, which are the parent material of steel wire. We will omit the discussion on wire rods for welding electrodes, but since there are students at our school who may advance to "Twist University" in the future, we will touch on soft steel wire rods and primarily explain hard steel and piano wire rods. For new students who find the JIS numbers and symbols difficult and don't know where to look, let me explain how to search for them. *You can view the detailed content of the article in the PDF.
