1. Product Description
The Billets as raw materials, through furnace heating, high-pressure water to reduce the phosphorus, then entering the roughing mill, cutting head, end, and then put into the finishing mill, cutting the edge, after the times of straightening, leveling and other finishing line treatment, and then cutting board or coil becomes the hot rolled steel sheet and hot rolled steel coil.
2. Main Features
Characteristics of hot rolled steel hot-rolled steel is a high temperature heating and rolled steel, hot rolled product has high strength, good toughness, easy to processing molding and good weldability and other excellent properties, which are widely used in ship, automobile, Bridges, buildings, machinery, pressure vessels and other manufacturing industries.
3. Excellent Product Image
4. Application
Refers to the production according to the requirements of classification society rules for the construction of hot rolled steel plate used in the manufacture of hull structure.
Because of poor working conditions, hull shell to chemical corrosion and electrochemical corrosion of sea water and sea creatures, microbial corrosion; Hull bear larger impact waves and alternating load; Ship shape the processing method of complex factors, so strict in hull structure steel. First good toughness is one of the most critical requirements, in addition, require high strength, good corrosion resistance, weldability, processing forming performance and surface quality. For assuring quality and ensure there is enough toughness and requirements of the chemical composition of the Mn/C above 2.5, also has strict requirements for carbon equivalent, and recognized by the survey department of steel production. Hull with structural steel in accordance with the minimum yield point strength level is divided into: general strength structural steel and high strength structural steel. General strength and high strength steel with hull structural steel points two kinds, general strength steel according to quality points A, B, D and E four grades; Strength of high strength steel and two levels and three quality grades; AH32, DH32, EH32, AH36, DH36, EH36.
China classification society standard the general strength of structural steel is divided into: A, B, D, E four quality levels (i.e., CCSA CCSB, CCSC, continental scientific drilling (CCSD); China classification society standard level of strength of high strength structural steel for three, four quality grade.

- Q:How are steel strips stored to prevent contamination?
- Steel strips are typically stored in a clean and dry environment, away from potential sources of contamination such as dust, moisture, and chemicals. They are often wrapped in protective materials or placed in sealed containers to ensure their integrity. Additionally, storage areas are usually kept organized and free of debris to minimize the risk of contamination.
- Q:What are the factors that affect the electrical conductivity of steel strips?
- The factors that affect the electrical conductivity of steel strips include the composition of the steel, impurities present, temperature, and the presence of any protective coatings.
- Q:How are steel strips heat-treated for improved strength?
- Steel strips are heat-treated for improved strength by subjecting them to a specific heating and cooling process called annealing. This process involves heating the steel strips to a high temperature and then slowly cooling them down. This controlled thermal treatment helps in relieving internal stresses, refining the microstructure, and ultimately enhancing the strength and hardness of the steel strips.
- Q:What is the difference between carbon steel and stainless steel strips?
- Carbon steel and stainless steel strips differ primarily in their composition and corrosion resistance. Carbon steel contains a higher amount of carbon, which enhances its strength and hardness. It is more affordable and commonly used for applications that require toughness, such as construction and machinery. Stainless steel, on the other hand, incorporates a higher level of chromium, which provides excellent corrosion resistance. Due to its ability to resist rust and staining, stainless steel strips are suitable for applications in food processing, medical equipment, and chemical industries.
- Q:What is the corrosion resistance of a galvanized steel strip?
- The corrosion resistance of a galvanized steel strip is very high due to the protective layer of zinc that is applied to the steel surface. This zinc coating acts as a barrier, preventing the steel from coming into direct contact with moisture and oxygen, which are the main causes of corrosion. As a result, galvanized steel strips are highly resistant to rust and can withstand harsh environmental conditions for extended periods of time.
- Q:Can steel strips be used in the production of roofing materials?
- Indeed, roofing materials can benefit from the utilization of steel strips. Steel, a robust and long-lasting substance, is frequently employed in construction, particularly for roofing purposes. It is common to employ steel strips as the foundation for roofing panels or sheets. Typically, these strips receive a protective coating, such as zinc or a blend of zinc and aluminum, to bolster their resistance against corrosion and extend their lifespan. Moreover, steel strips can be molded into diverse shapes and profiles to meet the specific demands of various roofing systems. In summary, steel strips provide numerous advantages for roofing materials, encompassing strength, durability, and adaptability.
- Q:Are steel strips suitable for the manufacturing of electrical motors?
- Yes, steel strips are suitable for the manufacturing of electrical motors. Steel strips offer excellent magnetic properties and high strength, making them ideal for use in electrical motor applications. They provide efficient energy transfer and reduce energy loss, resulting in improved motor performance and efficiency. Additionally, steel strips are readily available and cost-effective, making them a popular choice in the manufacturing of electrical motors.
- Q:What are the main challenges in handling and storing steel strips?
- The main challenges in handling and storing steel strips include their heavy weight and sharp edges, which can pose safety risks to workers. Additionally, steel strips are prone to rust and corrosion if not stored properly, requiring proper protection and climate control. Another challenge is the need for specialized equipment and storage facilities to accommodate their size and shape, ensuring efficient organization and accessibility.
- Q:How are steel strips used in the production of oil and gas equipment?
- Steel strips are commonly used in the production of oil and gas equipment due to their durability and strength. They are often formed into various shapes and sizes to create components such as pipes, casings, and valves. These steel strips are then processed through welding, cutting, and shaping techniques to meet specific requirements. The high-quality steel strips provide the necessary structural integrity and resistance to corrosion, ensuring the reliability and longevity of the oil and gas equipment.
- Q:What are the common surface finishes for carbon steel strips?
- Some common surface finishes for carbon steel strips include mill finish, hot-dip galvanized, electro-galvanized, and painted coatings.
