Introduction to types of spring steel wire, their applications, and the production process.
[Reproduction of Private Spring Preparatory School Lecture 34] Introduction to soft steel wire, hard steel wire, piano wire, and welding rod core wire!
Now that the new students have arrived, we will temporarily pause our studies on heat treatment and start with materials for springs, beginning with steel wire. I feel sorry for the new students, but if any unfamiliar terms come up during the lecture, please ask the seniors from the second-year repeaters for help. It’s fine to jump straight into spring steel wire, but remember the saying, "Spring days are long, and haste makes waste." I will digress a bit, but it would be beneficial to introduce the various types of wires, as it will help in understanding spring steel wire. *For detailed content, please refer to the PDF.
