Where to use BV FH40 marine steel material

In the development process of more than 20 years, the company keeps pace with the times, keeps innovating its ideas, constantly adjusting its steel product structure, constantly strengthening its comprehensive competitiveness, constantly improving its management level, and more importantly, forming its corporate culture of elements and personality. The company always strives to build itself a comprehensive competitive steel supplier in the world.

BV FH40 marine steel material,Q235 steel is ordinary carbon structural steel, also called Q235 ms plate. Q235 steel plates are popular among a large number of buildings and engineering structures. Q235 steel can be used to make steel bars or to build workshop frames, high-voltage transmission towers, bridges, vehicles, boilers, vessels, ships, etc. Q235 steel is also widely used as BV FH40 marine steel material mechanical parts with low performance requirements. Sometimes Q235C steel and Q235D steel can also be used as special steel.

BV FH40 marine steel material,The Performance requirements of low alloy structural steel, :
(1) High strength: generally, the yield strength is above 300Mpa.
(2) High toughness: the elongation is required to be 15% - 20%, and the room temperature impact toughness is greater than 600kJ/m ~ 800kJ/m. For large welded components, higher fracture toughness is required.
(3) Good weldability and cold forming property.
(4) Low cold brittle transition temperature.
(5) Good corrosion resistance.

BV FH40 marine steel material,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 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.

BV FH40 marine steel material,Pressure vessel steel plates are mainly used for manufacturing pressure vessels and other similar equipment for gas separation and gas storage and transportation in petroleum and chemical industry. Generally, the working pressure of pressure vessel steel plates ranges from normal pressure to 320kg / cm2 or even 630kg / cm2, and the temperature ranges from - 20 °C to 450 °C. In addition to certain strength, good plasticity and toughness, pressure vessel steel plates must also have good cold bending and welding properties. Q245R, Q345R, 14Cr1MoR, 15CrMoR, BV FH40 marine steel material etc. are common pressure vessel steel grades.

BV FH40 marine steel material,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.
