Do you know stainless steel plates?

Stainless steel plate is the general name of the stainless steel plate and acid-resistant steel plate. It has been more than 90 years since it came out at the beginning of this century. Now let's take a look.

What is stainless steel plate?

Stainless steel plate refers to a steel plate that is resistant to weak medium corrosion such as atmosphere, steam, and water, while acid-resistant steel plate refers to a steel plate that is resistant to chemical corrosion of acid, alkali, and salt. The stainless steel plate has been published at the beginning of this century and has been in the history of more than 90 years. The invention of stainless steel plates is a great achievement in the history of metallurgy in the world. The development of stainless steel plates has laid an important material and technical foundation for the development of modern industry and scientific and technological progress. There are many kinds of stainless steel plates with different properties. They have gradually formed several kinds in the development process. At present, the commonly used classification method is based on the characteristics of steel plate structure and chemical composition, as well as the combination of the two. Generally divided into martensitic stainless steel plate, ferritic stainless steel plate, austenitic stainless steel plate, duplex stainless steel plate, and precipitation hardening stainless steel plate, or divided into chromium stainless steel plate and nickel stainless steel plate. Typical uses: pulp and paper equipment, heat exchanger, mechanical equipment, dyeing equipment, film processing equipment, pipeline, building external materials in coastal areas, etc.

What are the physical properties of stainless steel plates?

The total heat transfer coefficient of metal depends not only on the thermal conductivity of metal but also on other factors. In most cases, the film heat dissipation coefficient, rust scale, and metal surface condition. Stainless steel can keep the surface clean, so its heat transfer performance is better than other metals with higher thermal conductivity. Oxygen plus gas flame can not cut stainless steel plates because stainless steel is not easy to be oxidized. 5cm thick stainless steel plate should be processed with special cutting tools.

What are the corrosion conditions of stainless steel plates?

1. There is dust containing other metal elements or attachments of different metal particles on the surface of stainless steel. In the humid air, the condensation water between the attachments and stainless steel connects them into a micro battery, causing an electrochemical reaction and damaging the protective film, which is called electrochemical corrosion.

2. The organic juice (such as melon and vegetable, noodle soup, phlegm, etc.) adhered on the surface of stainless steel forms organic acid in the presence of water and oxygen, and the corrosion of organic acid on the surface of the metal will occur for a long time.

3. There are acid, alkali, and salt substances on the surface of stainless steel (such as alkali water and lime water splashing on the decoration wall), causing local corrosion. The above conditions can cause damage to the protective film on the surface of stainless steel and lead to corrosion.
