The company adopts the RINA grade D stern frame steel international advanced management system, and has passed the certification of ISO9001 quality management system, ISO14001 environmental management system and GB / T28001-2001 occupational health and safety RINA grade D stern frame steel management system, and has realized the comprehensive integration of the three systems. In the future development path, the company will adhere to the guidance of scientific development concept, accelerate the implementation of six development strategies, namely, the main business development strategy, cost leading strategy, science and technology innovation strategy, management upgrading strategy, green steel strategy, and Harmonious Co construction strategy, promote the company's sustainable development, and build the company into the most competitive modern steel group.
The boiler steel plate is used to manufacture various boilers and important accessories. Because the RINA grade D stern frame steel boiler steel plate works under the medium temperature (below 350 ° C) and high pressure state, it is not only subject to high pressure, but also to impact, fatigue load and water and air corrosion. The boiler steel plate is required to ensure certain strength and good welding and cold bending performance.Bridge steel plate RINA grade D stern frame steel is used for large railway bridge. The bridge steel plate is required to bear dynamic load, impact, vibration, corrosion resistance, etc.
Spring steel, as we can clearly know from its name, is one of the main materials used to make springs and special alloy steel for other elastic components. RINA grade D stern frame steel, Spring steel has good comprehensive properties, it has heat resistance, low temperature resistance, oxidation resistance, corrosion resistance and so on advantages. Compared with alloy spring steel, carbon spring steel has less advantages, but its price is cheaper, and the source of raw materials is convenient. The disadvantage of carbon spring steel is that the elastic limit is low and it is easy to lose elasticity after repeated deformation.
Magnetic particle flaw detection is only suitable for detecting surface defects, which means that by laying magnetic powder on the surface of the equipment and using its aggregate shape on the surface defects of the magnetic material equipment to determine the position, size and shape of the defect. This RINA grade D stern frame steel method has a relatively low cost and is easy for steel production enterprises to adopt in batches. However, for special steel profiles with deeper thickness, whether this method is used to detect hidden defects is yet to be verified.
