Classification of Stainless Steel Plate

Feb. 05, 2020

Stainless steel plate is a general term for stainless steel plate and acid-resistant steel plate. The development of stainless steel plates has laid an important material and technical basis for the development of modern industry and technological progress. There are many types of stainless steel plates and different performances, and they gradually formed several major categories in the development process. The following 316 Stainless Steel Plate Supplier will give you a specific introduction.


According to the structure, it is divided into four categories: austenitic stainless steel plate, martensitic stainless steel plate (including precipitation hardening stainless steel plate), ferritic stainless steel plate, and austenitic and ferritic duplex stainless steel plate.

According to the main chemical composition of the steel plate or some characteristic elements in the steel plate, it is classified into chrome stainless steel plate, chrome nickel stainless steel plate, chrome nickel molybdenum stainless steel plate, and low carbon stainless steel plate, high molybdenum stainless steel plate, high purity stainless steel plate and so on.

According to the performance characteristics and uses of steel plates, they are divided into nitrate-resistant stainless steel plates, sulfuric acid-resistant stainless steel plates, pitting-resistant stainless steel plates, stress-corrosion-resistant stainless steel plates, and high-strength stainless steel plates.

According to the functional characteristics of steel plates, they are divided into low temperature stainless steel plates, non-magnetic stainless steel plates, free-cutting stainless steel plates, and superplastic stainless steel plates.

The commonly used classification method is to classify according to the structural characteristics of the steel plate, the characteristics of the chemical composition of the steel plate, and the combination of the two. Generally divided into martensitic stainless steel plates, ferritic stainless steel plates, austenitic stainless steel plates, duplex stainless steel plates and precipitation hardening stainless steel plates, etc. or divided into two categories: chromium stainless steel plates and nickel stainless steel plates.

Stainless steel plates are used in a wide range of applications. Typical applications are: heat exchangers for pulp and papermaking equipment, machinery, dyeing equipment, film processing equipment, pipes, and materials used in buildings in coastal areas. The common ones are 316 Stainless Steel Sheet, etc.

There are two types of hot rolling and cold rolling according to the manufacturing method, including thin cold plates with a thickness of 0.5.10-885 mm 72938 and medium-thick plates with a thickness of 4.5-100 mm. According to the structural characteristics of steel types, it is divided into 5 types: austenite type, austenite-ferrite type, ferrite type, martensite type, and precipitation hardening type.

It can withstand the corrosion of various acids such as oxalic acid, sulfuric acid-ferric sulfate, nitric acid, nitric acid-hydrofluoric acid, sulfuric acid-copper sulfate, phosphoric acid, formic acid, acetic acid, etc. It is widely used in chemical industry, food, medicine, papermaking, petroleum, atomic energy, etc. Industry, as well as various parts of construction, kitchenware, tableware, vehicles, household appliances.


In order to ensure that the mechanical properties such as yield strength, tensile strength, elongation and hardness of various types of stainless steel plates meet the requirements, the steel plates must be subjected to heat treatment such as annealing, solution treatment and aging treatment before delivery. The corrosion resistance of stainless steel mainly depends on its alloy composition (chrome, nickel, titanium, silicon, aluminum, manganese, etc.) and its internal structure.


The surface of the stainless steel plate is smooth, has 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 it is not absolutely rust-free.
