Detailed introduction of cold-rolled stainless steel plate:

Production process:
Cold-rolled stainless steel plate is a steel plate made by further rolling hot-rolled stainless steel slab to the target thickness at room temperature. It is usually a process of hot rolling → pickling → cold rolling. Compared with hot-rolled steel plates, there is no high-temperature processing process during the cold rolling process, its thickness is more precise, the surface is smooth and beautiful, and it also has various excellent mechanical properties, but the cold-rolled original coil is brittle and hard, not suitable for processing, and generally requires annealing, pickling and surface flattening before it is delivered to customers

Thickness specification:
The thickness range of cold-rolled stainless steel plates is usually 0.03 - 3mm. Among them, the thickness of 0.3 - 3mm is thin plate, and the thinner one, such as 0.03 - 0.3mm, belongs to precision ultra-thin cold-rolled stainless steel plate strip. For example, Yongjin Co., Ltd. can sell in bulk various soft and hard ultra-precision stainless steel plates and strips with thicknesses of 0.05mm-1.5mm and widths of 10mm-1250mm, and the thinnest thickness can be 0.03mm.

Performance characteristics:

Good mechanical properties: It has high strength and hardness, and good toughness, and can meet a variety of complex processing and use requirements. For example, it is used to manufacture mechanical parts, structural parts, etc., and can withstand certain loads and stresses.
 

High dimensional accuracy: The thickness accuracy can be controlled within a small range, and the flatness of the plate surface is good, which can ensure the consistency and stability of the product size. It is very suitable for some application scenarios with high dimensional accuracy requirements, such as electronic equipment and precision instrument manufacturing.
 

Excellent surface quality: The surface is smooth and beautiful, without oxide scale and other defects, and presents a good metallic luster. In some fields with high requirements for appearance, such as architectural decoration, furniture manufacturing, etc., cold-rolled stainless steel plates can be used directly or with simple surface treatment to achieve the ideal decorative effect.
 

Strong processing performance: It has good cold processing forming performance and can be made into products of various shapes and structures through bending, stamping, stretching and other processing methods. For example, it can be processed into stainless steel sinks, kitchen utensils, electrical appliance housings, etc.
 

Good corrosion resistance: It is mainly composed of alloy elements such as chromium and nickel, which makes it have good corrosion resistance and can resist the erosion of most acids, alkalis, salts and other media. It is widely used in corrosive environments in the chemical, food, and pharmaceutical industries. For example, it is used to manufacture chemical equipment, pipelines, food processing equipment, etc.

Application areas:

Electronic information industry: It can be used to manufacture the shells, internal structural parts and various precision parts of electronic products such as mobile phones and computers, such as mobile phone middle frames and computer keyboard frames. Its good dimensional accuracy and surface quality can meet the requirements of miniaturization, lightness and beauty of electronic products.
Automobile manufacturing industry: It is used for automobile body structural parts, engine parts, decorative strips, etc. High strength and good molding performance can ensure the safety and reliability of automobile parts, and its corrosion resistance can adapt to the use of automobiles in various environments.
Architectural decoration industry: It is commonly used in curtain walls, roofs, balcony railings, interior decoration and other aspects of buildings. Its beautiful surface and good weather resistance can not only enhance the appearance of the building, but also ensure that it is not easy to rust and corrode during long-term use.
Chemical equipment field: Because it can resist the erosion of various chemical media, it is widely used in the manufacture of reactors, storage tanks, pipelines, valves and other equipment in chemical production.
Food processing industry: It is used for food processing equipment, storage containers, transportation pipelines, etc., meets food hygiene standards, is corrosion-resistant and easy to clean, and can ensure the safety and hygiene of food.
Medical device field: such as surgical instruments, implants, dental equipment, etc., which have high requirements on the biocompatibility, corrosion resistance and processing accuracy of materials. Cold-rolled stainless steel plates can meet these requirements.
