Description
The technical field is as follows:
the invention relates to the technical field of fishhook products, in particular to a niobium-vanadium composite microalloyed high-carbon steel wire for a fishhook.
Background art:
fishhooks (fisherhooks), tools for hanging baits to attract fish to get caught on the hook while fishing. The fishhook consists of a handle head, a hook handle, a hook bend, a hook tip, a hook door and a hook bottom, and each part has a specific function and is a necessary tool for fishing.
The development of the existing fishhook is fast, the fishhook has various types, stainless steel and alloy steel made of carbon materials, and the fishhook has more types and sizes. The fishhook made of the material has the defects of insufficient hardness or high hardness but easy breakage, and the service performance and the service life cannot completely meet the requirements of users which are gradually developed.
In view of the above, the present inventors propose the following.
