What are the top ten S420ML material hot rolled plates mills in Vietnam

The company has S420ML material advanced production equipment and machining technology, excellent marketing team and domestic regional channel partners, and sound management plan for product market development and after-sales service. After years of cooperation experience S420ML material, we have accumulated a large number of customers at home and abroad, and won unanimous praise.

How much is the price of S420ML material, medium and heavy plate? First of all, there are many kinds of medium and heavy plate specifications, and the prices of different specifications are also different. Secondly, there are many kinds of medium and heavy steel plate materials. Different materials / steel grades have different uses, and the price will also change. Thirdly, we should also look at the manufacturers of steel products and pay attention to the steel grades of different manufacturers, so as to avoid buying poor quality medium and heavy steel plates.

The surface of alloy steel coil is specially treated during processing. The wear resistance of steel coil and plate made of alloy steel is much better than that of traditional rolling plate, and the cost is also low. The heat resistance and high temperature resistance of alloy steel coil is better than that of traditional rolling plate, and it will not deform easily. Besides, the strength of the S420ML material, alloy steel is very high, it is not easy to break and can be used for a long time.

After adding trace elements such as phosphorus, copper, chromium, and nickel to Q355NH steel, a dense and highly adherent protective film is formed on the surface of the weathering steel, which prevents rust from spreading and developing, and protects the substrate under the rust layer to slow its corrosion . An amorphous spinel oxide layer of about 50 μm to 100 μm thick formed between the rust layer and the substrate is dense and has good adhesion to the base metal, which greatly improves the atmospheric corrosion resistance of the steel material, S420ML material.

S420ML material, Q345 and Q345B are steel numbers. The differences are as follows:1. Q345 is general and does not indicate the quality level; Q345B is clear and the quality level is B.2. Q345 does not require to inspect the impact performance; Q345B requires that the impact performance at room temperature is qualified (impact at 20 ℃).3. Q345 does not indicate carbon content of steel; Q345B carbon content is 0.20%.Q345 refers to carbon structural steel with yield point (σ s) of 345MPa. The following letters indicate the quality level, including A, B, C, D and E.
