Q235D carbon steel plate sheet vs SA 36 sheet

Carbon steel mainly refers to the steel whose mechanical properties depend on the carbon content in the Q235D carbon steel plate sheet steel, and generally does not add a lot of alloy elements, sometimes it is also called ordinary carbon steel. Carbon steel refers to iron carbon alloy with carbon content of WC less than 2%. In addition to carbon, carbon steel generally contains a small amount of silicon, manganese, sulfur and phosphorus. According to the content of phosphorus and sulfur, the carbon steel can be divided into ordinary carbon steel, high quality carbon Q235D carbon steel plate sheet steel, high quality steel and super quality steel.

Ordinary carbon steel killed steel plate deoxidizes the liquid steel before making. When the liquid steel is poured into the ingot, its reaction is relatively calm and there is no boiling state. Advantages: this kind of steel plate Q235D carbon steel plate sheet has no gas, less impurities, uniform stress and good welding performance. Widely used in demanding parts

During the construction of hot-dip Q235D carbon steel plate sheet galvanized pipe, the correct welding process shall be adopted, the inspection and acceptance shall be carried out in strict accordance with the specification, and the anti-corrosion treatment (zinc rich paint) shall be done timely after the welding is completed. It is feasible in the construction process of open and closed air conditioning system, which can improve the Q235D carbon steel plate sheet construction speed and the firmness of the pipe connection. Therefore, the hot-dip galvanized pipe can be welded and connected under the construction conditions and on the premise of relevant protection and anti-corrosion measures.
