The company has A709 Gr 50W high strength steel 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 A709 Gr 50W high strength steel, we have accumulated a large number of customers at home and abroad, and won unanimous praise.
C45 steel heat treatment: Quenching has low hardenability, and it is easy to cause uneven hardness of the drill rod during heat treatment, resulting in deformation or even cracking. The hardness after quenching is about 42 degrees, which is much lower than the 55 degrees of 42CrMo brazing rod. Therefore, the wear resistance is extremely poor. Due to its low price, the A709 Gr 50W high strength steel materials are produced in many places. Therefore, some manufacturers choose when manufacturing low-cost drill rods.
The alloy steel plate has higher oxidation resistance and corrosion resistance, and is more suitable for use in acid and alkali environments. The surface of alloy steel plate will not be oxidized and corroded, maintaining the brightness of the steel plate. The alloy steel plate also has high material strength, its pressure bearing performance is very outstanding. It has high plasticity under the condition of long-lasting stretching. The A709 Gr 50W high strength steel, alloy steel plate is not prone to fracture, and it is more durable.
Superior process production line advantage sdf: The company has focused on weathering steel A709 Gr 50W high strength steel, pressure vessel plate, oil tank plate, pipeline steel plates, and steel welded structures for many years, and has a strong factory scale; one of the domestic excellent weathering steel manufacturers, serving customers all over the world; using frequency conversion and microcomputer program control, the equipment is highly automated; Improve product efficiency and improve product quality.
S355NL steel plate is under EN10111 standard. We can regard A709 Gr 50W high strength steel, S355NL steel plate as Fine-grain structural steels, normalised rolled. S355NL steel plate is one mainly of Fine-grain structural steels, normalised rolled, The normalized rolled fine-grain structural steel S355NL is characterized by a minimum yield strength of 355 MPa, by good weldability and high resistance to brittle fracture, which is same with DIN:TStE355 and BS:55EE
Customer first, reputation first, high-quality and perfect after-sales service is the extension of our product value and an important guarantee for the interests of customers. The purpose of our A709 Gr 50W high strength steel service quality management system is to establish and constantly improve a scientific, reasonable and efficient service quality management system, and complete the after-sales service quality guarantee work of customers fairly, accurately and timely, For our company's A709 Gr 50W high strength steel customer service to establish a good, comprehensive, full service system.
