Description

Technical Field

[0001] This utility model relates to the field of stainless steel technology, and in particular to a corrosion-resistant stainless steel. Background Technology

[0002] Stainless steel, with its unique rust resistance, beautiful surface finish, and high recyclability, is widely used in many important sectors of the national economy, including construction, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, catering, and electronics. As a large developing country in the early stages of industrialization, my country's national economic development should rely on the development of a modern steel industry as its backbone. The development of the stainless steel industry is the most important indicator of a country's overall steel industry development level and represents the future trend of the steel industry.

[0003] Currently, most stainless steel products have a single-layer structure, resulting in generally poor corrosion resistance. When exposed to acidic or alkaline environments for extended periods, stainless steel readily reacts with these acids or alkalis, leading to the release of harmful substances such as heavy metals. This damages the internal structure of the stainless steel, weakens its structural strength, and affects the normal operation of the product, ultimately reducing its overall performance. Furthermore, stainless steel is easily deformed under external impact during use, resulting in poor product quality, a short service life, and an inability to meet current demands. Therefore, it is necessary to research a new technical solution to improve current stainless steel products. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a corrosion-resistant stainless steel that effectively solves the problems of poor corrosion resistance of existing stainless steel. When exposed to acidic or alkaline environments for a long time, stainless steel easily reacts with acids or alkalis, leading to the precipitation of harmful substances such as heavy metals, damaging the internal structure of the stainless steel, weakening its structural strength, affecting the normal operation of the product, reducing the overall performance of the stainless steel product, and easily deforming when subjected to external impacts during use, resulting in poor product quality and short service life.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A corrosion-resistant stainless steel comprises a stainless steel base layer, a high-temperature resistant layer, a first reinforcing layer, a first reinforcing core, a first silicon carbide ceramic layer, a buffer layer, a second reinforcing layer, a second reinforcing core, and a second silicon carbide ceramic layer. The high-temperature resistant layer is stacked on the upper surface of the stainless steel base layer, effectively improving the high-temperature resistance of the product. The upper surface of the high-temperature resistant layer has multiple first grooves. The first reinforcing layer is stacked on the upper surface of the high-temperature resistant layer, and the lower surface of the first reinforcing layer has multiple first protrusions. These protrusions are respectively disposed in corresponding first grooves, and the cooperation between the protrusions and grooves effectively enhances the stability of the connection structure between the first reinforcing layer and the high-temperature resistant layer. Multiple first reinforcing cores are embedded in the first reinforcing layer, which greatly enhances the structural strength and improves the quality of the product. The first silicon carbide ceramic layer is disposed on the upper surface of the first reinforcing layer. Silicon carbide ceramic material has excellent corrosion resistance and can work stably for a long time in acidic, alkaline, and oxidizing environments. Silicon carbide ceramic material has high hardness and strength, and good high-temperature resistance, impact resistance, and wear resistance.

[0007] The buffer layer is stacked on the lower surface of the stainless steel base, effectively improving the product's cushioning and shock absorption performance. The lower surface of the buffer layer has multiple recessed second grooves. The second reinforcing layer is stacked on the lower surface of the buffer layer, and the upper surface of the second reinforcing layer has multiple protruding second protrusions, each positioned within a corresponding second groove. The coordinated arrangement of the second protrusions and second grooves effectively enhances the stability of the connection between the second reinforcing layer and the buffer layer. Multiple second reinforcing cores are embedded within the second reinforcing layer, significantly enhancing the product's structural strength and extending its service life. The second silicon carbide ceramic layer is located on the lower surface of the second reinforcing layer. Silicon carbide ceramic material possesses excellent corrosion resistance, enabling long-term stable operation in acidic, alkaline, and oxidizing environments. It also exhibits high hardness, high strength, and good high-temperature resistance, impact resistance, and wear resistance.

[0008] As a preferred embodiment, the stainless steel base layer is made of high-nitrogen austenitic stainless steel. High-nitrogen austenitic stainless steel has high strength, good corrosion resistance, and wear resistance. By replacing part of the expensive metal nickel with nitrogen, high-nitrogen austenitic stainless steel not only saves resources but also improves strength. This substitution strategy allows high-nitrogen austenitic stainless steel to maintain high performance while achieving lower costs.

[0009] As a preferred embodiment, the high-temperature resistant layer is made of polyetheretherketone (PEEK), which has properties such as high strength, corrosion resistance, radiation resistance, and flame retardancy, as well as good high-temperature resistance and insulation properties.

[0010] As a preferred embodiment, the buffer layer is made of polyurethane, which has high elasticity and good cushioning, shock absorption, corrosion resistance, wear resistance and impact resistance.

[0011] As a preferred embodiment, the first and second reinforcing layers are made of carbon fiber. Carbon fiber has very high strength, is lightweight, and has good high-temperature resistance, corrosion resistance, wear resistance, and electromagnetic shielding properties.

[0012] As a preferred embodiment, the cross-sections of the first reinforcing core and the second reinforcing core are triangular. The angular design of the first and second reinforcing cores can increase the contact surface, strengthen the structure, effectively enhance the product's bending and compressive strength, and improve its load-bearing capacity.

[0013] As a preferred embodiment, the plurality of first grooves are evenly spaced on the upper surface of the high-temperature resistant layer, and correspondingly, the plurality of first protrusions are evenly spaced on the lower surface of the first reinforcing layer.

[0014] As a preferred embodiment, the plurality of second grooves are evenly spaced on the lower surface of the buffer layer, and correspondingly, the plurality of second protrusions are evenly spaced on the upper surface of the second reinforcing layer.

[0015] As a preferred embodiment, the plurality of first reinforcing cores are respectively embedded in the corresponding first protrusions.

[0016] As a preferred embodiment, the plurality of second reinforcing cores are respectively embedded in the corresponding second protrusions.

[0017] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0018] By placing a first silicon carbide ceramic layer on the upper surface of the first reinforcing layer and a second silicon carbide ceramic layer on the lower surface of the second reinforcing layer, this double-layer silicon carbide ceramic structure significantly enhances the corrosion resistance of stainless steel. Even when exposed to acidic or alkaline environments for extended periods, it is less prone to chemical reactions with acids or alkalis, preventing the release of harmful substances, ensuring the stability of the stainless steel structure, guaranteeing normal product operation, and improving overall product performance. Furthermore, by embedding multiple first reinforcing cores within the first reinforcing layer and multiple second reinforcing cores within the second reinforcing layer, the coordinated arrangement of the first and second reinforcing layers, first and second reinforcing cores, effectively strengthens the product's structural integrity. It will not deform under external impact during use, improving product quality, extending its service life, and meeting current requirements.
