AI Technical Summary

Problems solved by technology

When the spring washer is applied, due to the extrusion of the nut and the bolt, a compressive stress is generated on the spring washer. Due to the insufficient mechanical properties of the spring washer, such as tensile strength, the spring washer is broken, so that the spring washer Tablet loses potency

Embodiment 1

[0042] The preparation method of the stainless steel wire described in the present application comprises the following steps:

[0043] S1: Alloy smelting to prepare steel ingots

[0044] (1) Preliminary smelting in induction arc furnace

[0045]The chemical elements are C: 1.2%; Mn: 1.25%; Cr: 17.40%; Ni: 9.12%; Ti: 0.2%; P: 0.028%; Add scrap steel, high-carbon ferrochromium, high-carbon ferromanganese, nickel plate and ferrotitanium into an induction arc furnace, gradually heat up, and smelt at 1570°C. Whether the element meets the requirements. If the chemical elements do not meet the requirements, adjust the composition until they meet the requirements; if the chemical elements meet the requirements, tap the steel for refining.

[0046] (2) Argon oxygen refining furnace for refining

[0047] The primary molten steel was added to an argon-oxygen refining furnace (AOD) for refining. In the oxidation stage of refining, the mixed gas is blown into the smelting, and the mix...

Embodiment 2

[0052] The difference between Example 2 and Example 1 is that the chemical elements adjusted in the refining process of Example 2 are: C: 0.04%; Si: 0.55%; Mn: 1.5%; Cr: 18.0%; Ni: 10.0%; Ti: 0.5%; P: 0.028%; S: 0.002%, the balance being Fe and inevitable impurities.

Embodiment 3

[0054] The difference between Example 3 and Example 1 is that the chemical elements adjusted in the refining process of Example 3 are: C: 0.03%; Si: 0.4%; Mn: 1.0%; Cr: 17.0%; Ni: 8.0%; Ti: 0.1%; P: 0.028%; S: 0.002%, the balance being Fe and inevitable impurities.

Abstract

The invention relates to the technical field of steel wire preparation, and particularly discloses a stainless steel wire and a preparation method and application thereof. A stainless steel wire includes: 0.03 to 0.04% of C; 0.4 to 0.55 percent of Si; 1.0 to 1.5 percent of Mn; cr: 17.0 to 18.0%; 8.0% to 10.0% of Ni; 0.1 to 0.5 percent of Ti; p is less than or equal to 0.03%; the tensile strength of the stainless steel wire is more than 1400 MPa, and the tensile strength of the stainless steel wire is more than 1400 MPa. The preparation method of the stainless steel wire comprises the steps of smelting, rolling, cold drawing, cold drawing, heat treatment and the like, the tensile strength of the stainless steel wire can be improved, and the tensile strength is 1450 MPa or above.

Description

technical field [0001] The present application relates to the technical field of steel wire preparation, and more particularly to a stainless steel wire and a preparation method and application thereof. Background technique [0002] With the rapid development of economy and the rapid development of transportation, marine engineering and construction engineering, higher requirements have been put forward for application security. In various fields, the steel structure is the most commonly used connection method, and the fastener is the most important element in the steel structure. The insufficient strength of the fastener directly affects the service life and safety of the steel structure. . [0003] Spring washers are the most commonly used and important type of fasteners, spring washers prevent the loosening of nuts. The anti-loosening principle of the spring washer is that after the spring washer is flattened, the spring washer will generate a continuous elastic force, ...
