Sliding bar

Abstract

The invention provides a sliding bar which comprises a bar body, a clamp and a clamping screw. The sliding bar is composed of, by weight, 1-1.2% of C, 0.8-1% of Si, 0.7-0.9% of Mn, 0.012-0.015% of P, 0.04-0.06% of S, 16-18% of Cr, 0.23-0.3% of Ti, 0.3-0.7% of Nb, 0.5-0.6% of Mo, 0.1-0.2% of Ce, 0.1-0.2% of La and the balance Fe. The sliding bar is not prone to being separated from a corresponding accessory and is quite reliable to use; meanwhile, precipitation of chromium carbide and chromium nitride can be reduced, and the mechanical property is high; the surface of the material is plated with Zn, the surface smoothness can be increased, and the self-cleaning effect is enhanced; and Ce and La facilitate improvement of the atmosphere corrosion resistance of the sliding bar, and a co-permeation layer enables the workpiece surface to be more resistant to abrasion and corrosion.

Description

technical field [0001] The invention belongs to the technical field of hardware accessories and relates to a sliding bar. Background technique [0002] The sliding rod is a commonly used hardware accessory with a wide range of applications. The main function of the sliding rod is to connect several structures or components together, and to bear the torque or force that needs to be transmitted when the parts move. [0003] Ordinary sliding rods use general stainless steel materials, and sliding rods will be stressed during use, so various mechanical properties of sliding rods, such as yield strength, tensile strength, elongation, etc. will be relatively high Requirements, and the current material of the sliding rod is generally stainless steel, and the use environment of the sliding rod is generally relatively harsh, often exposed to water vapor, and also exposed to an acidic or alkaline environment, often in this environment, it will slide Therefore, it is necessary to impr...

Problems solved by technology

[0003] Ordinary sliding rods use general stainless steel materials, and sliding rods will be stressed during use, so various mechanical properties of sliding rods, such as yield strength, tensile strength, elongation, etc. will be relatively high Requirements, and the current material of the sliding rod is generally stainless steel, and the use environment of the sliding rod is generally relatively harsh, often exposed to water vapor, and also exposed to an acidic or alkaline environment, often in this environment, it will slide Corrosion of the rod will reduce the expected energy of the sliding rod and may cause safety accidents. Therefore, it is necessary to improve a sliding rod with better mechanical properties and corrosion resistance to solve the current technical problems
