Abstract

The invention discloses a high-strength stainless steel fiber manufacturing method. The stainless steel fiber is characterized by comprising 1.1-3% of chromium, 1.1-1.2% of molybdenum, 0.85-1.1% of potassium, 0.01-1.1% of calcium, 0.35-0.4% of copper, 1-1.2% of zinc and 67-81% of iron. The manufacturing method is suitable for stainless steel wire drawing processing, realizes single wire diameter of 3 micrometers, strength more than 20n / mm<2> and an elongation percentage of 3.20%, greatly improves finished product integrated performances, completely solves the problem that the original stainless steel wire has poor fineness, is crisp and can be easily broken and has simple, convenient and easy processes.

Description

1. Technical field [0001] The invention belongs to the field of metal processing, in particular to a method for manufacturing high-strength stainless steel fibers. 2. Background technology [0002] Stainless steel (Stainless Steel) refers to steel that is resistant to weak corrosive media such as air, steam, water, and chemically corrosive media such as acid, alkali, and salt. It is also called stainless acid-resistant steel. In practical applications, the steel resistant to weak corrosion medium is often called stainless steel, and the steel resistant to chemical medium corrosion is called acid-resistant steel. Due to the difference in chemical composition between the two, the former is not necessarily resistant to chemical media corrosion, while the latter is generally stainless. In the production and processing of stainless steel wire, sometimes the stainless steel wire needs to be processed very thin, and its comprehensive performance is required to be still strong and ...
