The company has allocated special environmental protection facilities for all GL-FH 36 ocean engineering steel pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, GL-FH 36 ocean engineering steel steel mill scale, environmental protection dust has reached 100%.
Pressure vessel steel SA204GrA, SA204GrB, SA204GrC sheet delivery status: normalized rolling, maybe normalized, or other heat treatment methods may be negotiated with users for delivery. Generally, the thickness of the GL-FH 36 ocean engineering steel, ASME SA204 pressure vessel steel plate is ≤40mm, and it is generally delivered in the rolled state, and the SA204GrA steel plate of more than 40mm can be delivered in the normalized heat treatment state.
Compared with GL-FH 36 ocean engineering steel, boiler steel plates should have the following properties: (1) High medium temperature strength: low and medium pressure boiler drums use steel with a lower yield point, high pressure boilers use steel with a high yield point. (2) Good plasticity, impact toughness, cold bending and welding performance. (3) The notch sensitivity is small, that is, the sensitivity to the stress concentration caused by the opening of the steel plate surface and the welding of the pipe head is small.
The research methods of isothermal treatment of GL-FH 36 ocean engineering steel, wear-resistant plate include many excellent technologies, such as optical microscope, transmission electron microscope, X-ray diffractometer and electron backscatter diffraction technology. With the increase of annealing temperature, the proportion of ferrite in wear-resistant plate will gradually decrease, and bainite will increase, while the retained austenite will be distributed in ferrite grain boundary and crystal in elliptical and fine strip shape.
Hardness comparison between Q345B steel and NM450 steel: wear resistant steel for construction machinery requires high wear resistance, high toughness, impact resistance, easy welding, easy forming and other high-performance characteristics. The main index of wear resistance is the surface hardness. The higher the hardness, the better the wear resistance. Compared with GL-FH 36 ocean engineering steel, Q345B steel, the hardness of NM450 steel is only increased 3 times, but the average service life is increased 6-8 times under the same working conditions.
