Inox steel sheet is generally a general term for inox steel sheet and acid-resistant steel plate. There are many kinds of inox steel sheets and steel plates with different properties. According to the organization structure, it is divided into four categories: austenitic inox steel sheet, martensitic inox steel sheet (including precipitation hardened inox steel sheet), ferritic inox steel sheet, and austenitic plus ferritic duplex inox steel sheet. Next, I will continue to introduce you to the inox steel sheet.
What are the properties of inox steel sheets?
Under what circumstances will inox steel sheets corrode?
How to choose an inox steel sheet?
Corrosion resistance: The inox steel sheet can resist general corrosion similar to the unstable nickel-chromium alloy 304. Long-term heating in the temperature range of chromium carbide may affect alloys 321 and 347 in harsh corrosive media.
High-temperature oxidation resistance: inox steel sheets have high-temperature oxidation resistance, but the oxidation rate will be affected by inherent factors such as exposure environment and product form.
Physical properties: The total heat transfer coefficient of a metal depends on other factors in addition to the thermal conductivity of the metal. In most cases, the heat dissipation coefficient of the film, the scale, and the surface condition of the metal. An inox steel sheet can keep the surface clean and tidy, so the heat transfer performance of the inox steel sheet is better than other metals with higher thermal conductivity.
1. The surface area of the inox steel sheet has dust containing other metal elements or attachment of foreign metal particles. In humid air, the condensation water between accessories and stainless steel connects them to form a micro battery, which leads to the destruction of the protective film after a chemical reaction, which is called electrochemical corrosion.
2. Organic juices (such as melon seeds, vegetables, noodle soup, sputum, etc.) are attached to the surface of the inox steel sheet. Organic acids are formed in the presence of water and oxygen, which will corrode the metal surface for a long time.
3. The surface of the inox steel sheet is adhered to contain acid, alkali, and salt substances (such as alkaline water and lime water splashing on the decoration wall), causing local corrosion.
4. In polluted air (such as the atmosphere containing a lot of sulfides, carbon oxide, and nitrogen oxide), it will form sulfuric acid, nitric acid, and acetic acid liquid spots when encountering condensed water, causing chemical corrosion. The conditions above can cause the protective film on the surface of the inox steel sheet The damage caused rust.
The selection of inox steel sheets should consider the operating conditions, such as manual or automatic operation, the performance and type of the hot press, and the quality requirements of the pressed material such as hardness and gloss. We must also consider economic calculations. Every time a new steel sheet is polished, it is required to make a low-quality decorative sheet.
In addition, when choosing the most reasonable thickness of the inox steel sheet, its service time, quality and rigidity should be considered. At the same time, the strength requirements of the plate under compression; heat conduction performance; pressure distribution, and the size of the press plate should be considered. If the thickness of the inox steel sheet is not enough, it is easy to bend, which will affect the production of decorative plates. If the thickness is too large, the inox steel sheet is too heavy, which not only increases the cost of the inox steel sheet but also brings unnecessary difficulties to the operation. At the same time, the margin that should be left when the inox steel sheet is processed or used must be considered.
Today，Foshan TaiYuDa Steel Group Co., Ltd. has been well developed. And the intelligence of inox steel sheets is very high, and gradually tends to the unification of international standards. Whether it is a simple inox steel sheet or an intelligent inox steel sheet. Fiber inox steel sheet is an ideal choice.
