Abstract

The invention discloses a niobium-vanadium compound microalloyed high-carbon steel wire used for a fishhook. The niobium-vanadium compound microalloyed high-carbon steel wire used for the fishhook comprises the following components in percentage by mass: 0.8-1.4% of C, 0.08-0.20% of V, 0.02-0.08% of Nb, and the balance Fe. According to the niobium-vanadium compound microalloyed high-carbon steel wire used for the fishhook, through trace alloy element addition and reasonable chemical proportioning, a material has good cold working performance, it can be ensured that the produced fishhook has the grain size (GB / T 6394-2002) of 10 grade or more and the hardness of HV800 or more after being subjected to quenching and tempering heat treatment, and meanwhile, enough fracture toughness is maintained so that the material can be used for manufacturing a high-performance fishhook product.

Description

Technical field: [0001] The present invention relates to the technical field of fish hook, which refers to a tantalum-vanadium-vanadium composite micro-gold high carbon wire. Background technique: [0002] Fishhook, fishing for hanging bait while fishing to attract fish hooks. Hooks are composed of six parts of the tip, hook, hook, hook tip, hook door, and hook, each part has its own specific function, essential tool when fishing. [0003] Now the development of the fish hook is very fast, there are many kinds of stainless steel, and there is also a co-smaller classification of carbon materials. The above-mentioned materials have a shortcoming of a hardness or hardness of hardness or hardness but easily broken, and the useful service life cannot fully meet the growing user needs. [0004] In view of this, the inventors provide the following technical solutions. SUMMARY OF THE INVENTION [0005] It is an object of the present invention to overcome the shortcomings of the prior ar...
