What are the top ten S690QL properties hot rolled plates mills in Vietnam

The company adheres to the customer philosophy of "customer first, pursuit of excellence". With the service tenet of "low price, excellent quality, fast transportation and constant commitment", we are committed to providing S690QL properties high quality and timely steel products and services for steel users all over the world. And created a good customer reputation. The main products of the company are section steel, steel pipe, thin plate, rolling plate, medium and thick plate, etc.

SA516 70 grade has the highest tensile and yield strength range due to the highest carbon content (up to 0.28%). For high-grade S690QL properties steel plates such as SA516 70 grade, especially thick steel plates need to be preheated during arc welding.

Our company produces ordinary carbon steel S690QL properties with high strength and good plasticity and toughness. Due to the effect of alloy elements, its strength is 25% - 50% higher than that of ordinary carbon steel, its elongation is 15% - 23%, and its impact toughness at room temperature is higher than 60j / cm 2. We have a S690QL properties production line specializing in the production of ordinary carbon steel plate, and strictly control its quality.

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, S690QL properties.

The carbon content of S690QL properties, medium carbon steel plate is 0.25% - 0.60%. In addition to carbon, it can also contain a small amount of manganese (0.70% - 1.20%). The medium carbon steel plate after quenching and tempering has good comprehensive mechanical properties. The highest hardness is about HRC55 (hb538) and σ B is 600-1100mpa.

our company is leading supplier of API 5CT casing pipes in China. N80 oil casing pipes enjoy high size precision, good weld toughness, S690QL properties good extrusion resistance, easy quality control and low cost features. Welcome to our company to purchase S690QL properties API 5CT N80 and so on casing pipes.

Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel S690QL properties plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
