Stainless steel plate refers to a steel plate that is resistant to corrosion by weak media such as atmosphere, steam and water, while acid-resistant steel plate refers to a steel plate that is resistant to corrosion by chemically corrosive media such as acid, alkali, and salt. Stainless steel sheet is widely used because of its characteristics that it is not easy to rust. So what is stainless steel plate and what are the advantages of stainless steel plate?
Stainless steel plate has been around for more than a century since it came out in the early 20th century. The stainless steel plate has a smooth surface, high plasticity, toughness and mechanical strength, and is resistant to corrosion by acids, alkaline gases, solutions and other media. It is an alloy steel that does not rust easily, but not rust-free. Stainless steel plate is generally a general term for stainless steel plate and acid-resistant steel plate. Stainless steel sheet refers to a steel plate that is resistant to corrosion by weak media such as atmosphere, steam and water, while acid-resistant steel plate refers to a steel plate that is resistant to corrosion by chemically corrosive media such as acid, alkali, and salt. Since the advent of stainless sheets at the beginning of this century, the development of ss plate has laid an important material and technical foundation for the development of modern industry and scientific and technological progress.
There are many types of stainless steel plates with different properties, including embossed stainless steel sheet and ss 304 sheet, etc.. It has gradually formed several categories in the process of development. The commonly used classification method is to classify according to the structural characteristics of the steel plate, the chemical composition characteristics of the steel plate and the combination of the two. It is generally divided into martensitic stainless steel, ferritic stainless steel, austenitic stainless steel, duplex stainless steel and precipitation hardening stainless steel. Or it is divided into two categories: chromium stainless steel plate and nickel stainless steel plate. Stainless steel sheet suppliers produce products for a wide range of uses, and its typical uses include pulp and paper equipment heat exchangers, mechanical equipment, dyeing equipment, film processing equipment, pipelines, and exterior materials for buildings in coastal areas.
(1) Corrosion resistance. Stainless steel sheet has a similar resistance to general corrosion as the unstable Nichrome 304. Prolonged heating in the temperature range of chromium carbide degrees may affect Alloys 321 and 347 in harsh corrosive media. It is mainly used in high temperature applications, which require strong resistance to sensitization of the material to prevent intergranular corrosion at lower temperatures.
(2) High temperature oxidation resistance. Stainless sheets have high temperature oxidation resistance. However, oxidation rates are affected by inherent factors such as exposure environment and product form.
(3) Physical properties. The overall heat transfer coefficient of a metal depends on other factors besides the thermal conductivity of the metal. In most cases, this includes the heat dissipation coefficient of the film, the scale and the surface condition of the metal. Stainless steel keeps the surface clean, so it conducts heat better than other metals with higher thermal conductivity.
