What is the specific use of A514 Gr R alloy steel plate, hot rolled plate in daily life? First of all, hot rolled plate is used in bridge, vehicle structure, frame and other fields to play a role of bearing pressure. Secondly, high pressure boiler vessels are also made of hot rolled plates, which can be heat-resistant and airtight, and can stably seal the hot gas in the container. Thirdly, stainless steel hot rolled plate can be used to process hardware products. It has excellent corrosion resistance, and is easy for processing.
Recently, the A514 Gr R alloy steel plate price has fallen into a dilemma, and Tangshan production restriction has started again. When the market transaction is weak, the A514 Gr R alloy steel plate price gain support again. Although the high demand is not good at present, which will restrain the rise of A514 Gr R alloy steel plate price, the preference of market mentality and cost side make most A514 Gr R alloy steel plate manufacturers optimistic about the prosperous season. Therefore, it is expected that the A514 Gr R alloy steel plate price will be easy to rise and difficult to fall in the near future, so it is suggested that businesses can make up stocks at low prices.
The quality of carbon steel is distinguished by the amount of sulfur (s) and phosphorus (P) in the steel. When the A514 Gr R alloy steel plate sulfur content in carbon steel is not more than 0.050% and the phosphorus content is not more than 0.045%, it is ordinary carbon steel; when the sulfur content and phosphorus content in carbon steel are less than 0.040%, it is high-quality carbon steel; when the A514 Gr R alloy steel plate sulfur content in carbon steel is less than 0.030% and the phosphorus content is less than 0.035%, it is high-quality carbon steel.
