High quality low alloy ASME SA709 carbon steel plate sheet properties

The steel used for bridge beams should also have excellent welding function and low notch sensitivity, high strength, toughness, and load and impact from rolling stock, as well as outstanding fatigue resistance, certain low temperature resistance, and atmospheric corrosion resistance. Q460qC steel plate delivery status: ASME SA709 carbon steel plate sheet steel products are delivered in hot rolled, controlled rolled or normalized conditions.

The overall intention of supporting prices in the raw material market is relatively strong, but the steel mills have a low acceptance of high prices, and some just need a small amount of goods, so the overall market game state is obvious. With the poor release of steel demand, terminal merchants tend to consume low-cost inventory in the early stage and purchase on demand to avoid the risk of large-scale hoarding. However, the cost side is weak, and some ASME SA709 carbon steel plate sheet manufacturers secretly reduce prices to promote transactions. It is expected that the ASME SA709 carbon steel plate sheet market will be stable and weak in the future.

Try to use ASME SA709 carbon steel plate sheet 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 ASME SA709 carbon steel plate sheet temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.
