The company adheres to the management concept of "people-oriented, talent is concerned", develops business with the spirit of "believing strength, practical style, A573 grade 70 steel sheet professional service and dare to compete", and provides customers with "professional, value-added and effective" service support. For the company's development and take-off, we work together to move forward and create a better A573 grade 70 steel sheet tomorrow!
What should be paid attention to when using A573 grade 70 steel sheet, carbon steel? First, the strength level of carbon steel is low and it is easy to fracture, so carbon steel is not suitable for high strength engineering. Second, the heat-resistant performance of carbon steel is relatively poor, which can not be applied in the long-term high-temperature fields such as boilers. Third, the carbon steel is extremely easy to rust, so it is not suitable for water transport projects. Therefore, the use of carbon steel depends on the use of the environment, if it is harsh conditions, it is better to choose other steel materials.
Compared with A573 grade 70 steel sheet, ordinary steel plate, ship plate has better resistance to wind and wave. In the ocean, there are often big winds and big waves. If the performance advantage of ship plate is not prominent, it is easy to be damaged by big waves. The service life of ship plate is longer than that of ordinary steel plate. Because of its excellent performance, the ship plate can be used for a long time. Some waste ships can remove the ship plate for recycling. The price of ship plate is higher than ordinary steel plate.
Welding is mainly used for manufacturing metal structure parts, and also for manufacturing machine parts. The welding connection performance is good, and it is convenient to weld A573 grade 70 steel sheet steel plates, profiles or castings and forgings according to the needs. At the same time, welding can also connect different shapes and sizes (plate thickness, pipe diameter) or even different materials, so as to reduce weight, save materials, optimize resources and other purposes. The welding structure has high rigidity, good integrity, and easy to ensure air tightness and water tightness, so it is especially suitable for A573 grade 70 steel sheet manufacturing hollow structures with high strength and large rigidity (such as pressure vessels, pipes, boilers, etc.).
The S355 steel material itself is divided into many grades, so it cannot be said that S355 is equivalent to which grade of the national standard Q345, A573 grade 70 steel sheet. In engineering, usually S355JR steel is equivalent to Q345B steel, S355J0 steel is equivalent to Q345C steel, S355J2 steel is equivalent to Q345D steel, S355N steel is equivalent to Q345D steel, and S355NL steel is equivalent to Q345E steel.
As one of the large professional metallurgical manufacturers in China, the strength of the brand, quality assurance, professional after-sales. Every day we are making unremitting efforts to challenge higher quality A573 grade 70 steel sheet products and more satisfactory services. Customer demand is our pursuit, and win customer satisfaction with quality. BBN after-sales team is responsible to solve the problem of technical support and quality, service complaints.
