Advantages of SA572 Grade 50 alloy steel equivalent: 1. Steel purity: Wugang can produce high purity molten steel with P 0.010%, S 0.005%, N70ppm, O15ppm, H2ppm, and 20ppm total inclusions in the steel. 2. Good toughness and weldability. 3. The heat treatment technology: normalizing, quenching, tempering, tempering and other heat treatment processing can be carried out on the steel plate as required. 4. Significantly improve the plasticity and impact toughness of steel, and improve the anisotropy of steel.
Try to use SA572 Grade 50 alloy steel equivalent high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the SA572 Grade 50 alloy steel equivalent temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.
A514 Gr P steel plate is high strength quenched and tempered alloy steel, which is an American standard steel plate. SA572 Grade 50 alloy steel equivalent, A514 Gr P steel plate has high tensile strength and yield strength. It is commonly used in the manufacture of offshore platform, mining and various construction machinery and other structural parts. With the development of industry and the discovery of more and more offshore oil, the market demand for A514 Gr P steel plate is increasing.
Many people will mix strip steel and steel plate together, which can usually be distinguished from the following points. First of all, the thickness of the steel plate is much thicker, and the thinner the strip steel is required, the better. Secondly, in appearance, the steel strip can be crimped and the steel plate is too thick to bend, even if it is bent, it is difficult to recover, because it is easy to break if it is bent too much. Thirdly, the strength of SA572 Grade 50 alloy steel equivalent, steel plate is higher than that of strip steel. The steel plate is suitable for construction engineering, while strip steel is only suitable for processing into hardware products.
