Q235NH weathering steel plate need painting or not

Myanmar's demand for Q235NH weathering steel plate steel products is likely to exceed 3 million tons in 2020 and 5 million tons by 2025, according to seaisi. However, Myanmar's producers are unable to meet domestic demand, so the country's steel products are more dependent on imports. In 2019, Myanmar imported more than 1.9 million tons of Q235NH weathering steel plate finished steel, including 57% of long products, 13% of uncoated hot-rolled and cold-rolled flat products, and 30% of coated steel. In order to reduce its dependence on imports, Myanmar plans to increase its steel production capacity by building and expanding steel mills.

Every after-sales service shall have a detailed record of the customer's product problems and handling methods. The records shall be sorted into volumes and filed on a monthly basis, and submitted to the technical department for filing. The problems found in the after-sales service shall be summarized in a timely manner, discussed with the technical department, the quality inspection department and the production department, and a proper solution shall be proposed for the technical department to improve in a timely manner;

Hot continuous rolling can be divided into ordinary carbon structural steel, low alloy steel and alloy steel according to their different materials and properties. According to the different uses, Q235NH weathering steel plate it can be divided into: cold forming steel, structural steel, automobile structural steel, corrosion-resistant structural steel, mechanical structural steel, welding gas cylinder steel and pressure vessel steel, pipeline steel, etc.

SA516Gr.70 steel chemical composition (%):C≤0.30, Mn: 0.79-1.30, P≤0.035, S: ≤0.035, Si: 0.13-0.45. ASME SA516Gr.70 material is a carbon steel grade for medium and low temperature pressure vessels. In order to meet the different requirements of users and facilitate production management, the S and P requirements of steel grades are divided into three levels of Ⅰ, Ⅱ and Ⅲ. Q235NH weathering steel plate, SA516Gr.70 pressure vessel steel is used to improve the notch toughness of welding steel plates for pressure vessels.
