A572Gr50 steel plate is a steel plate grade under American standards and is a type of low-alloy high-strength steel plate. At present, the strength requirements of steel plates are relatively high, but there are still requirements for thickness, so these high-strength steel plates came into being. For example, A572Gr50 steel plate adds a small amount of alloy elements inside the steel plate. After passing through a special heat treatment process, the strength and toughness of the steel plate can be partially improved to meet the requirements and can be used.
2. A572Gr50 uses an electric furnace to make steel. It is made from scrap iron. The steel is pure. The steel plate is a flat steel plate that is poured with molten steel and pressed after cooling. It is flat and rectangular, and can be directly rolled or cut from wide steel strips. Steel plates are divided by thickness, thin steel plates <8 mm (thinnest 0.2 mm), medium-thick steel plates 8~60 mm, extra-thick steel plates 60~120 mm
3. A572Gr50 steel plate implementation standard: implement ASTM standard.
4. A572Gr50 steel plate delivery status: The steel plate is delivered in hot rolling, controlled rolling, normalizing, etc. The delivery status can also be specified according to technical requirements.
5. Performance requirements in the thickness direction of A572Gr50 steel plate: Z15, Z25, Z35.
6. A572Gr50 steel plate flaw detection requirements: first detection, second detection, third detection.
7. A572Gr50 steel plate density: 7.85/cubic meter.
8. A572Gr50 steel plate weight adjustment formula: thickness * width * length * density.
9. Regular size of A572Gr50 steel plate: 8-80mm*2000-2500mm*8000-10000mm
4. Surface quality requirements of A572Gr50 steel plate
The surface of the steel plate should not have bubbles, scars, cracks, folds, inclusions, and pressed iron oxide scales that would affect the use and harmful defects. The steel should not have visually visible layering. The surface of the steel is allowed to have thin layers of iron oxide scale and rust that do not hinder the inspection of surface defects, as well as inconspicuous roughness, meshes, scratches and other local defects caused by pressing into the iron oxide scale and rollers, but their depth should not be greater than that of the steel. Half of the thickness tolerance, and the minimum allowable thickness of the steel should be ensured. Surface defects of the steel are allowed to be removed by grinding and other methods. The cleaned area should be smooth and without edges. The cleaning depth should not be greater than the negative deviation of the steel thickness, and the allowable minimum thickness of the steel should be ensured. minimum thickness
