Stainless Steel Strip Coil

Hot rolled stainless steel strip is a high-quality stainless steel material produced by a hot-rolling process. It is made of various stainless steel grades such as austenitic, ferritic, martensitic and has high corrosion resistance and excellent mechanical properties. Hot rolled stainless steel strip is commonly used in a variety of industries, including automotive, construction and home appliances. It is also suitable for applications requiring high temperature resistance and high strength properties. Its excellent formability enables it to be processed into different shapes and sizes, making it ideal for a variety of manufacturing processes.

Hot rolling is to use slab (mainly continuous casting slab) as raw material, and after heating, it is made into strip steel by rough rolling unit and finishing rolling unit. The hot steel strip coming out of the last rolling mill of finishing rolling is cooled to the set temperature by laminar flow, and rolled into steel strip coils by the coiler. The cooled steel strip coils undergo different finishing operations according to different needs of users. Wire (leveling, straightening, cross-cutting or slitting, inspection, weighing, packaging and marking, etc.) processed into steel plate, flat coil and slitting steel strip products. To put it simply, after a steel billet is heated, it is rolled several times, then trimmed, and corrected into a steel plate. This is called hot rolling.

Features of hot rolled stainless steel strip:
1. High-strength hot rolled strip steel has high strength and hardness, which can meet the requirements of high-strength engineering projects in various industries.
2. Good plasticity Hot rolled steel strip has good plasticity, and can be shaped by cold working, bending, etc., to meet the needs of different shapes and sizes.
3. Excellent welding performance The hot rolled steel strip can maintain good welding performance during the welding process, with high welding strength and good weld quality.
4. Strong wear resistance The hot rolled steel strip has been specially treated, the surface hardness is high, and it has good wear resistance, which is suitable for occasions that need to be frequently worn.
5. Good corrosion resistance After anti-corrosion treatment, the hot-rolled steel strip has good corrosion resistance and can be used for a long time in humid and corrosive environments.

Application of hot rolled stainless steel strip:
1. Automobile manufacturing Hot rolled strip steel is widely used in the automobile manufacturing industry to manufacture body, frame, door and other components. Its high strength and wear resistance can improve the safety and service life of the car.
2. Construction engineering Hot rolled strip steel is used for structural parts in construction engineering, such as beams, columns, bridges, etc. Its high strength and plasticity can meet the needs of construction engineering for strength and shape requirements.
3. Hot rolled strip steel in the petrochemical industry is used in the manufacture of pipes, containers and other equipment in the petrochemical industry. Its corrosion resistance can meet the needs of petrochemical industry for corrosion resistant materials.
4. Machinery manufacturing hot rolled steel strips are used in various machinery and equipment in the machinery manufacturing industry, such as pressure vessels, machine tools, etc. Its high strength and weldability can improve the service life and safety of mechanical equipment.
5. Hot-rolled steel strips in the aerospace field are used in the manufacture of aerospace fields, such as aircraft structural parts, engine parts, etc. Its high strength and light weight can improve aircraft performance and fuel efficiency.
6. Hot rolled strip steel in the electric power industry is used in the manufacture of transmission towers, substations and other equipment in the electric power industry. Its high strength and corrosion resistance can meet the requirements of the power industry for material strength and durability.
Hot rolled strip steel has the characteristics of high strength, good plasticity, excellent welding performance, strong wear resistance and good corrosion resistance, and is widely used in automobile manufacturing, construction engineering, petrochemical, machinery manufacturing, aerospace, electric power and other industries . With the continuous advancement of science and technology and continuous improvement of technology, hot rolled strip steel will be more widely used in various industries and make greater contributions to the development and progress of society.

Different countries have different standards for stainless steel hot-rolled strips. The following are some common national standards:

Chinese standard:
Stainless steel commonly used standard GB/T 4237-2015 "Stainless steel hot-rolled steel plate and strip"

British Standard:
BS EN 10088-2-2014 "Stainless steel. Technical delivery conditions for general purpose corrosion resistant steel sheet/plate and strip"

American standard:
ASTM A240/A240M-20a, Standard Specification for Pressure Vessels and Chromium and Chromium-Nickel Stainless Steel Plate, Sheet, and Strip

Japanese standard:
JIS G4304:2005 "Hot-rolled stainless steel plate, sheet and strip"

This standard specifies the classification, code, order content, size, shape, weight and allowable deviation, technical requirements, test methods, inspection rules, packaging, marks and product quality certificates of stainless steel hot-rolled steel sheets and strips.

Common specifications for hot-rolled strip steel are:
Basic size 1.2～25×50～2500mm
Generally, the bandwidth below 600mm is called narrow strip steel, and the one above 600mm is called wide strip steel.
Coil weight: 5 to 45 tons
Thickness: 2.0~8.0 mm
Width: 16~600mm
Inner diameter: 610mm
