Why Q235NH tower steel is not easy to rust

Based on the Q235NH tower steel steel trade, the company mainly deals in Baosteel products: color coating, zinc plating, fingerprint resistance, cold rolling, hot rolling, pickling, electrical steel and other products, and can order the futures of the company's products on behalf of manufacturers. It has established cooperative relations with more than 2000 foreign customers. At the same time, it also operates a variety of products of related iron and steel enterprises. Annual sales of Q235NH tower steel steel 3.6 million tons, standing stock of 400000 tons, has developed more than 10000 users. The company has a first-class marketing service system, strong storage and transportation capacity and supporting supply, cutting distribution capacity, and gradually build it into an important marketing channel.

316 Vs 304: ASTM 316L(1.4404) is a low-carbon austenitic chromium-nickel-molybdenum steel. Due to the addition of 2-2.5% molybdenum, the corrosion resistance of the stainless steel 316L is significantly better than that of the standard austenitic grades 304 and 304L, Q235NH tower steel. The 1.4404 material is resistant to intercrystalline corrosion when welded! but not resistant to sea water. Best corrosion resistance is given with a polished surface. This material is comparable to 1.4401.

The steel plate for hull structure is also called marine plate or shipbuilding steel. Due to the harsh working environment of the ship, the hull shell is subject to the chemical corrosion of seawater, so the requirements for steel for the hull structure are strict. First of all, good toughness for marine plate Q235NH tower steelis the most critical requirement. In addition, it requires higher strength, good corrosion resistance, welding performance, processing performance and surface quality.

With the increase of carbon content in the steel material, the yield point and tensile strength increase, but the plasticity and impact decrease. When the carbon content is more than 0.23%, the welding performance of the steel material becomes worse. Therefore, the carbon content of low alloy structural steel used for welding is generally less than 0.20%. The high carbon content can also reduce the atmospheric corrosion resistance of steel material, and the high carbon steel in the open air is easy to rust; in addition, carbon can increase the cold brittleness and aging sensitivity of Q235NH tower steel etc. steel material.
