How much is the marine steel price per ton?According to the difference of quality grade and strength grade, as well as the difference of plate size, production area, and user requirement, the price of A573 Gr 70 structural steel plate plate fluctuates greatly. At present, the market price of marine plate is about 3800 yuan per ton to 5800 yuan per ton. Generally, the most commonly used marine plate price is about 4000 yuan per ton.
The company's operation is based on the principle of "quality for survival, reputation for development". In terms of management, we adhere to the principle of people-oriented, service-oriented and customer-oriented. All staff of the company have the courage to open up, unite and forge ahead, and work hard to grasp the good situation of global economic development, actively strengthen communication with outstanding enterprises in the A573 Gr 70 structural steel plate industry, keep pace with the times, and move towards a new course!
X-rays or γ-rays are projected on the surface of the steel plate, and rubber can be placed on the other side of the steel plate. Since the radiation propagates through the steel plate and is absorbed, the intensity is different due to the presence or absence of defects, so the film can record the shape and position of the defects. This A573 Gr 70 structural steel plate method is sensitive to the detection of common steel plate defects such as slag inclusions, porosity and pores. The disadvantage is that it is difficult to find the specific depth of the defect and it is not easy to find cracks.
The sulfur element (S element) comes from the ore and fuel coke of steelmaking. It is a harmful element in A573 Gr 70 structural steel plate etc. steel. Sulfur exists in steel in the form of iron sulfide (FeS). FeS and Fe form a low melting point (985℃) compound. The hot working temperature of steel is generally above 1150 - 1200℃, so when the steel is hot working, the premature melting of FeS compound causes the workpiece to crack, which is called "hot brittleness". It reduces ductility and toughness of steel and causes cracks during forging and rolling. Sulfur is also detrimental to welding performance and reduces corrosion resistance.
The company strengthens process management and pays attention to assessment. One of the key points of good service is to strengthen the process management and improve the evaluation mechanism. Make the after-sales service system more perfect and provide better service for customers.
