The stainless steel plate refers to the steel plate that is resistant to the corrosion of weak media such as steam and water, and the acid-resistant steel plate refers to the steel plate that is resistant to the corrosion of chemical etching media such as acid, alkali, and salt. The stainless steel plate has a smooth surface, high plasticity, toughness and mechanical strength, and has strong corrosion resistance to acids, alkaline gases, solutions and other media. It is an alloy steel that is not easy to rust. Stainless steel plate is usually the collective name of stainless steel plate and acid-resistant steel plate. During the development process, several categories of stainless steel plates of various properties were gradually formed. It is divided into four types: austenitic stainless steel plate, martensitic stainless steel plate (including precipitation hardening stainless steel plate), ferritic stainless steel plate, and austenitic ferritic duplex stainless steel plate.
The stainless steel plate has corrosion resistance, which is the same as Ni-Cr alloy 304, which is resistant to general corrosion. Prolonged heating in the chromium carbide grade temperature range affects the performance of alloys 321 and 347 in harsh corrosive media. Emphasis on high temperature applications. In high-temperature applications, strong resistance to sensitization of the material is required in order to prevent intergranular corrosion at low temperatures. The stainless sheet has high temperature oxidation resistance, and the stainless steel plate has oxidation resistance. However, the rate of oxidation is influenced by inherent factors such as exposure environment and product form. The stainless steel plate has a smooth surface, high plasticity, toughness and mechanical strength, and has strong strength against acids, alkaline gases, solutions and other media. Although it is an alloy steel that is not easy to rust, it will never rust. The stainless sheet is an alloy steel that is not easy to rust. The stainless steel plate has many characteristics such as corrosion resistance, oxidation resistance, and surface smoothness.
Stainless steel wire drawing, widely used in production and life. Why should stainless steel be brushed, and what is the difference between brushed and non-drawn stainless steel? Below, Shanghai Bao New Group will answer from four dimensions: the pursuit of aesthetics, consideration of practical functions, lower acquisition cost, and ease of later maintenance.
1. The pursuit of beauty For the sake of beauty, that is, out of the demand for appearance design. A certain surface texture can give Lishun stainless steel products a unique visual expression, enhance product attractiveness, and promote product sales. The stainless steel plate is brushed on the surface, combined with/highlight, sandblasting, etching, color plating and other processes to obtain rich appearance effects, and can be applied to scenes such as daily necessities, instruments, equipment, machinery, etc.
2. Practical function considerations The surface of stainless steel plate is brushed, which can have various surface and texture effects. The stainless steel wire drawing with different roughness can meet the needs of various occasions, such as: the inner and outer walls of the cylinder (tank), panels, shells, etc.
4. It is convenient for later maintenance. The original stainless sheet is or is the effect produced by hot rolling/cold continuous rolling, pickling and other links. In case of dirt, blemishes, etc., it is difficult to make the blemishes consistent with the whole by means of grinding and other means. The brushed surface is suitable for various instruments and equipment, and is compatible with possible appearance defects and non-mark repair requirements. At this time, people choose to remove the original surface of the steel plate to obtain the brushed effect. Of course, the price of the same stainless steel plate is different between brushed and non-brushed, the former is slightly higher than the latter. Whether the stainless steel is brushed or not, and why stainless steel should be brushed is related to the actual use requirements. If you need the advantages of brushed stainless steel and can accept the disadvantages of brushed stainless steel (the unit price is slightly higher), Dingliang Metal recommends using brushed stainless steel plate.
