Stainless steel plate is a term that encompasses both stainless steel plates and acid-resistant steel plates. Emerging at the dawn of the 20th century, the evolution of stainless steel plates has established a critical material and technological foundation for modern industrial development and scientific advancements. These plates come in a vast array of types with diverse properties. Structurally, they are categorized into four main types: austenitic stainless steel plate, martensitic stainless steel plate, ferritic stainless steel plate, and austenitic-ferritic duplex stainless steel plate. Based on performance, they are sorted into acid-resistant, pitting-resistant, and high-strength stainless steel plates. Typical applications include pulp and paper equipment, heat exchangers, mechanical equipment, pipelines, and coastal construction materials.
