Preferably, the first protective sleeve and the second protective sleeve are both rubber sleeves and are used for providing certain protection for the outside of the knitting needle body, reducing abrasion of the knitting needle body and prolonging service life.
Preferably, the reinforcing ribs are made of stainless steel materials, so that the overall strength of the knitting needle body is improved, and the toughness is enhanced.
Preferably, the area on stainless steel layer, carbon steel layer and aluminiferous layer reduces in proper order, the stainless steel layer has better toughness and corrosion resistance, the carbon steel layer has stronger hardness, difficult fracture, the aluminiferous layer has better corrosion resistance, and the quality is light moreover.
Preferably, the wear-resistant layer is a high manganese steel layer, and the high manganese steel has the advantage that the larger the external impact is, the higher the wear resistance of the surface layer itself is, and a new work-hardened layer is continuously formed as the surface-hardened layer is gradually worn.
The high-strength high-wear-resistance needle provided by the invention has the beneficial effects that:
1. the stainless steel layer has good toughness and corrosion resistance, the carbon steel layer has strong hardness and is not easy to break, and the aluminum layer has good corrosion resistance and light weight, so that the strength and the wear resistance of the knitting needle body are greatly improved;
2. the first protective sleeve and the second protective sleeve are both rubber sleeves and are used for providing certain protection for the exterior of the knitting needle body, reducing the abrasion of the knitting needle body and prolonging the service life;
3. the wearing layer is high manganese steel layer, and the benefit of high manganese steel lies in that external impact is big more, and its self top layer wearability is higher, along with the gradual wear on case hardening layer, new processing hardening layer can constantly form in succession.
