Abstract

The invention relates to a nickel-cobalt alloy stainless steel wire which comprises, by weight, 0.001%-1.25% of Fe, 1.22%-1.25% of Co, 10%-20% of Cr, 1%-5% of Mo, 4%-6% of Nb + Ta, 0.001%-3% of Al, 0.001%-2% of Ti, 0.001%-0.1% of C, 0.01%-0.03% of P, 0.001%-0.01% of Mg, 0.001%-0.02% of B, 0.001%-0.1% of Zr, 3%-8% of Si and the balance Ni. According to the nickel-cobalt alloy stainless steel wire and a production process thereof, the oxidation resistance of the nickel-cobalt alloy stainless steel wire in severe environments such as high humidity and high temperature is improved, and the service life of the nickel-cobalt alloy stainless steel wire is prolonged. Through the drawing cooling device, cooling of the nickel-cobalt alloy stainless steel wire after drawing is completed is achieved, the situation that the nickel-cobalt alloy stainless steel wire is shrunk and broken or scratched in the rolling process is prevented, and meanwhile the functions of cleaning and lubricating the nickel-cobalt alloy stainless steel wire are achieved.

Description

technical field [0001] The invention relates to a nickel-cobalt alloy stainless steel wire and a production process thereof, belonging to the field of stainless steel wire production. Background technique [0002] Nickel (Ni) and cobalt (Co) are widely used as alloying elements for the production of stainless steel, superalloys, magnetic materials and catalysts, respectively. [0003] Stainless steel is the abbreviation of stainless and acid-resistant steel. The steel that is resistant to weak corrosive media such as air, steam and water or has stainless steel is called stainless steel; Corrosion) steel is called acid-resistant steel. [0004] Stainless steel wire, also known as stainless steel wire, is a variety of silk products of different specifications and models made of stainless steel. Nickel-cobalt alloy stainless steel wire, nickel has the effect of anti-corrosion, and cobalt has the effect of solid solution strengthening, giving the steel hot hardness and improvi...
