Manufacturing process of stainless steel plate

A stainless steel sheet is a very important industrial material. Due to its high strength, corrosion resistance, and beautiful appearance, it is widely used in construction, aviation, electronics, petrochemical, and other fields.

Here is the outline:

1. What are the classifications of stainless steel plates?

2. Manufacturing process of stainless steel plate

Classification

Stainless steel plates can be classified according to different materials, surface treatment methods, thickness, width, and other characteristics.

material

Austenitic stainless steel plate: including 201, 304, 316, 321, and other materials, with excellent corrosion resistance and a wide range of applications.

Ferritic stainless steel plate: including 430, 444, and other materials, with excellent heat resistance and oxidation resistance, suitable for high-temperature and low-temperature environments.

Martensitic stainless steel plate: including 410, 420, 440, and other materials, with high hardness and strength, widely used in automobiles, ships, and other fields.

Surface treatment

2B board: matte surface, commonly used in industrial fields.

BA board: the surface is glossy, and it is used in areas with high decoration.

HL board: the surface is brushed, with a criss-cross matt effect, suitable for architectural decoration and other fields.

According to the thickness, stainless steel plates can be divided into thin plates and thick plates.

definition

Stainless steel plate is a metal sheet made of stainless steel alloy. A stainless steel alloy is a steel material with corrosion-resistant properties consisting of iron, chromium, nickel, and other elements. There are various types of stainless steel sheets, which can be a thick plates, medium plates, thin plates, and ultra-thin plates to meet the needs of different applications.

manufacture

The manufacture of stainless steel plates is a multi-step process, which includes the steps of steelmaking, rolling, cooling, pickling, sulfuric acid oxidation, cold rolling, annealing, and polishing.

steelmaking

The production of stainless steel plates begins with steelmaking. Stainless steel alloys usually consist of iron, chromium, nickel, and other elements. These elements are mixed together through a metallurgical process, then heated and cooled to form a billet.

rolling

Rolling is the process of pressing a billet into sheet metal. This process is divided into two types, hot rolling, and cold rolling. Hot rolling is carried out at a high temperatures, so that the metal plate has high plasticity and plasticity, while cold rolling is carried out at normal temperatures.

The manufacturing process of stainless steel plate

The manufacturing process of stainless steel plate usually includes hot rolling, cold rolling, stretching, and so on. Among them, hot rolling and cold rolling are the most common manufacturing processes.

The hot rolling manufacturing process

The hot rolling manufacturing process is to heat the stainless steel billet to a high-temperature state, and then process the billet into the required plate thickness and size by rolling machinery. The hot rolling manufacturing process produces thicker stainless steel sheets and is often used in heavy industry.

the cold rolling manufacturing process

The cold rolling manufacturing process is to process the stainless steel billet into the required thickness and size of the plate at room temperature. The cold rolling manufacturing process can produce thin and flat stainless steel sheets, which are often used in the manufacture of precision instruments and electronic products.

stretch manufacturing process

The stretching manufacturing process is to heat the stainless steel sheet to a high-temperature state, and then stretch the sheet into the desired shape and size through a stretching machine. The stretching manufacturing process can produce complex-shaped stainless steel sheets, which are often used in the manufacture of aerospace devices.
