St52-3 steel, normal strength hull structural steel GL-B is low alloy high strength steel. The main characteristics of St52-3 steel are high tensile strength and yield point. St52-3 steel is used in civil construction, underground engineering, bridge structure, ocean structure, container manufacturing, automobile and machine manufacturing. Based on the principle of quality oriented, the company has established a perfect quality standard inspection system to provide customers with high-quality and low-cost steel products and after-sales services, which has been supported and praised by new and old users from all walks of life.
Advantages of NM360 wear-resistant steel plate: NM360 steel has high strength: generally its 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, high fracture toughness is also required. 3. NM360 steel plate has good welding performance and cold forming performance. 4. Low cold and brittle transition temperature.
Preheating cutting: The most effective way to prevent steel plate cutting cracks is to preheat before cutting. Before flame cutting, the steel plate is usually preheated, and the preheating temperature mainly depends on the quality level and thickness of the steel plate. The preheating method can be carried out with flame burner, electronic heating pad, or heating furnace. In order to determine the preheating effect of the steel plate, the required temperature should be tested at the heating point.
The company has accumulated rich experience in long-term cooperation with new and old customers, which makes our products normal strength hull structural steel GL-B more unique in the same industry, and is favored and praised by users.
