  • In the corner area, the zinc layer is often thicker than other places, and has good toughness and abrasion resistance. And other coatings in this corner, often Z thin Z is not easy to construction, Z is easy to hurt, so often need to be maintained. Even if there’s a lot of mechanical damage or something. Causing a small layer of zinc to peel off, leaving the iron base exposed, the surrounding zinc layer will act as a sacrificial anode to protect the steel from erosion.

  • The tensile strength of cold drawn spring steel wire is slightly higher than that of oil tempered steel wire. The large specification of cold drawn steel wire elastic force is too large, winding the spring is very difficult, so the cold drawn spring steel wire application specification is generally less than 8.0mm, oil quenching tempered steel wire application specification is generally less than 13.0mm. In fact, the diameter of 13.0mm spring is used to light tension spring steel wire, cold drawing wound made into shape and then quenched and tempered. Steel wire with diameter above 15.0mm is mostly made by heating winding process.
