Grade EH36 marine steel: E is the quality grade E, H is the high-strength building material, 36 is the maximum compression, and Z is the Z-direction stretching. Grade EH36 structural steel for high-strength hull refers to the steel used for manufacturing the hull structure produced according to the requirements of the classification society. Our company mainly supply Grade EH36 hot rolled plate, military grade ABS AH36 ship steel, Grade EH36 angle steel bars and steel sections.
Flat steel is a kind of steel with rectangular cross-section and blunt edges at the edges and corners. It is usually 12-300 mm wide and 3-60 mm thick. Compared with military grade ABS AH36 ship steel ordinary steel plate, the utilization rate of flat steel is increased by one to five percentage points. Moreover, flat steel can be produced with fixed thickness, width and length according to the user's requirements, which saves the cutting process for users, reduces the consumption of labor and materials, and also reduces the processing loss of raw materials, saving time, labor and material.
Vanadium element (V element) can refine grains in ordinary low carbon alloy steel, improve the strength and yield ratio and low temperature characteristics after normalizing, and improve the welding performance of steel, military grade ABS AH36 ship steel included. Vanadium element (V element) is often used in combination with manganese, chromium, molybdenum, tungsten and other elements in structural steel because of its low hardenability under general heat treatment conditions. Vanadium in quenched and tempered steel is mainly to improve the strength and yield ratio of steel, refine the grain size, and pick up the overheating sensitivity.
