Our company will set up a full-time service engineer for the project, who is responsible for the interface and coordination of technical support and after-sales service of the s420 steel mechanical properties project. In response process of customer service center, in case of technical support and after-sales service demand, the user shall contact the full-time engineer of s420 steel mechanical properties customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.

A709GR50 steel plates are used in construction steel structure, construction machinery and other steel structures, such as construction steel structure, construction machinery, mining and mountain machinery, heavy trucks, bridges, pressure vessels, etc., especially for requirements with better weldability And tough construction and construction machinery parts. The product s420 steel mechanical properties has been exported to South Korea, Taiwan and other places, and the cumulative export volume has reached more than 10,000 tons.

20Mn2 steel has medium strength, and the properties of 20Mn2 steel and 20Cr steel are similar. The impact toughness and weldability of 20Mn2 steel at low temperature are better than those of 20Cr steel. The plasticity and machinability of 20Mn2 steel are high during cold deformation. The hardenability of 20Mn2 steel is higher than that of corresponding carbon steel, s420 steel mechanical properties. Chemical composition of 20Mn2 steel: C: 0.17-0.24, Si: 0.17-0.37, Mn: 1.40-1.80. Mechanical properties of 20Mn2 steel: tensile strength ≥ 785 MPa, yield strength ≥ 590 MPa, elongation after fracture ≥ 10%, section expansion rate ≥ 40%, impact absorbed energy ≥ 47J.

Alloy steel plate is a kind of high strength steel plate with excellent performance in all aspects. In the current market environment, the performance requirements for steel plate are also higher and higher, ordinary steel plate has been far from meeting the market demand, and the emergence of alloy steel plate has broken this deficiency. The alloy steel plate is improved from the traditional steel plate, which is a new high improvement to the performance of the traditional steel plate. Today let us have a learn of s420 steel mechanical properties, alloy steel plate together.

Our company has established and constantly improved the customer service system and emergency response system. Through the customer service management system, we track the service of the after-sales service team and provide efficient and standard services in time. At the same time, the company formulates a regular return visit system, compares the historical cases of customer problems, proposes a pre solution, and ensures that the service is in place in a short time.

We have a professional production team and high-quality production equipment, and we also have a great s420 steel mechanical properties advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the s420 steel mechanical properties production of high-quality steel plates, steel pipes and other products that meet customer requirements.
