Stainless Steel Plate

     Stainless steel plate has a smooth surface and high plasticity, toughness, and mechanical strength. It is resistant to corrosion from acids, alkaline gases, solutions, and other media. It is a rust-resistant alloy steel, but it is not completely rustproof. Stainless steel plate refers to steel plate that is resistant to corrosion from weak media such as air, steam, and water, while acid-resistant steel plate refers to steel plate that is resistant to chemically aggressive media such as acids, alkalis, and salts. Stainless steel plate has been around for over a century since its introduction in the early 20th century.

     Stainless steel plate is generally a general term for both stainless steel and acid-resistant steel plates. Its introduction in the early 20th century laid an important material and technological foundation for the development of modern industry and technological advancement. There are many types of stainless steel plate with varying performance characteristics, and several major categories have gradually emerged over the course of its development. Based on microstructure, stainless steel is categorized into four major categories: austenitic stainless steel, martensitic stainless steel (including precipitation-hardening stainless steel), ferritic stainless steel, and austenitic-ferritic duplex stainless steel. Based on the primary chemical composition or characteristic elements in the steel, it can be divided into chromium stainless steel, chromium-nickel stainless steel, chromium-nickel-molybdenum stainless steel, low-carbon stainless steel, high-molybdenum stainless steel, and high-purity stainless steel. Based on performance characteristics and applications, it can be divided into nitric acid-resistant stainless steel, sulfuric acid-resistant stainless steel, pitting-resistant stainless steel, stress-corrosion-resistant stainless steel, and high-strength stainless steel. Based on functional characteristics, it can be divided into low-temperature stainless steel, non-magnetic stainless steel, free-cutting stainless steel, and superplastic stainless steel. The commonly used classification method is based on the microstructure and chemical composition of the steel, or a combination of the two. Generally, it can be divided into martensitic stainless steel, ferritic stainless steel, austenitic stainless steel, duplex stainless steel, and precipitation-hardening stainless steel, or into two major categories: chromium stainless steel and nickel stainless steel. Widely used. Typical applications include heat exchangers in pulp and papermaking equipment, machinery, dyeing equipment, film processing equipment, pipelines, and exterior materials for coastal buildings.

Corrosion Resistance

Stainless steel plate has similar resistance to general corrosion as the more unstable nickel-chromium alloy 304. Prolonged heating within the chromium carbide temperature range may affect alloys 321 and 347 in harsh corrosive media. It is primarily used in high-temperature applications, which require strong resistance to sensitization to prevent intergranular corrosion at lower temperatures.

High-Temperature Oxidation Resistance

Stainless steel plate exhibits high-temperature oxidation resistance, but the oxidation rate is affected by inherent factors such as the exposure environment and the product's form.
