SA572 grade 42 carbon steel plate sheet prices should not have a sharp drop for a short period of time

The difference between SA572 grade 42 carbon steel plate sheet, hot rolled sheet and cold rolled sheet: hot rolled sheet has low hardness, easy processing and good ductility. The cold-rolled sheet has high hardness and relatively difficult processing, but it is not easy to deform and has high strength. The cold rolled sheet is mostly used in automobile manufacturing and electrical products. Therefore, the two have their own characteristics. According to these characteristics, it is more appropriate to choose the right rolled plate to maximize its effect and benefit.

The advantages of SA572 grade 42 carbon steel plate sheet, medium and thick boiling steel plate: The surface is relatively smooth, the quality is good, and it is easy to process. Because medium and thick boiling steel plate does not have concentrated shrinkage holes, the amount of deoxidizer is small, and boiling steel plate price is lower than other steel plates. Disadvantages of medium and thick boiling steel plate: it has a lot of gas content and impurities, it is not easy to weld, and its bearing capacity is worse than other steel plates, so it is not suitable for parts that need to bear gravity.

SA572 grade 42 carbon steel plate sheet, S690Q plate is used to manufacture low-temperature resistant, high-strength key components, construction machinery, mining machinery structures, etc. It is a high-strength structural steel plate.S690Q mechanical performance analysis:The thickness of S690Q is 8mm-50mm, the yield strength is not less than 690, the tensile strength is 770-940, and the elongation is not less than 14.The thickness of S690Q is 50mm-100mm, the yield strength is not less than 650, the tensile strength is 760-930, and the elongation is not less than 14.S690Q thickness is 100mm-150mm, yield strength is not less than 630, tensile strength is 710-900, elongation is not less than 14.
