The company has allocated special environmental protection facilities for all RINA grade D stern frame 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, RINA grade D stern frame steel steel mill scale, environmental protection dust has reached 100%.
Q370R steel and 15CrMoR plates have low sulfur and phosphorus content, and have good comprehensive mechanical properties, welding performance and low temperature impact toughness. Q370R low alloy steel is suitable for manufacturing medium temperature and low pressure pressure vessels and their accessories. RINA grade D stern frame steel, 15CrMoR material has low sulfur and phosphorus content, and has good welding performance and impact toughness.
Wear resistant plate is composed of two parts, namely carbon steel plate and alloy wear-resistant layer. Under normal conditions, the thickness of the RINA grade D stern frame steel alloy wear-resistant layer of the wear-resistant plate is 1 / 3-1 / 2 of the total thickness. When working, the matrix provides the strength, toughness, plasticity and other comprehensive properties to resist external forces, and the alloy wear-resistant layer provides the RINA grade D stern frame steel wear-resistant property to meet the requirements of specific working conditions.
RINA grade D stern frame steel, Q345B low alloy steel plate composition: 1) Low carbon: Due to the high requirements for toughness, weldability and cold forming properties, its carbon content does not exceed 0.20%; 2) Add manganese-based alloying elements; 3) Adding auxiliary elements such as niobium, titanium or vanadium: a small amount of niobium, titanium or vanadium forms fine carbides or carbonitrides in the Q345B steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of the steel; In addition, adding a small amount of copper (≤0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. Adding a small amount of rare earth elements can desulfurize and degas, purify steel, improve toughness and process performance.
