MS Carbon Steel S690QL chemical composition

Based on the main business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and S690QL chemical composition heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel products are exported S690QL chemical composition to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

Q345 steel has good comprehensive mechanical properties, acceptable low temperature performance, good plasticity and weldability. Q345 steel is used to make mechanical parts, building structures, general metal structural parts for medium and low pressure containers, oil tanks, vehicles, cranes, mining machinery, power stations, bridges and other structures that bear dynamic loads. S690QL chemical composition It is used in hot rolled or normalized state. In addition, Q345 steel is also widely used in construction, bridges, vehicles, ships, pressure vessels, etc.

The cold working performance of S690QL chemical composition and so on steel structure engineering steel is good, which can ensure that the steel will not crack or brittle fracture during high-temperature processing, and will not have a great impact on strength, plasticity and toughness due to processing. The durability of S690QL chemical composition and so on steel structure engineering steel is good. Durability refers to the service life of steel structure. The main factor affecting the service life of steel is the poor corrosion resistance of steel, followed by the deterioration of mechanical properties of steel under long-term load, repeated load and dynamic load.

Primary processing, steel plate cutting processing cutting method, it is a flame cutting, because it to the accuracy requirement of the cutting size is not very high, the thickness of the S690QL chemical composition plates in a certain range can be a good cutting quality and cutting effect, and the cut surface can be very smooth, however, it is important to note that in this work, is the need to pay attention to steel plate deformation at high temperature.

10CrMo9-10 seamless pipe implements European standard EN 10216-2. The chemical composition of 10CrMo9-10 seamless pipe: C 0.08-0.14, Si ≤ 0.50, Mn 0.30-0.70, P ≤ 0.025, S ≤ 0.020, Cr 2.00-2.50, Ni ≤ 0.30, Mo 0.90-1.10, Al ≤ 0.04, Cu ≤ 0.03. The mechanical properties of 10CrMo9-10 seamless pipe: tensile strength: 450-530 MPa, yield strength: ≥ 280 MPa, elongation: ≥ 22%, impact energy: ≥ 40J. S690QL chemical composition, 10CrMo9-10 seamless pipe is a kind of high temperature and high pressure boiler steel, which is mainly used in the production of power station boiler, steam boiler equipment, pressure vessel, large pressure pipe, etc.

The after-sales service department will pay return visit to each customer by call or email, report problems found during the return visit in time, and discuss with the production and quality inspection center to propose effective solutions and follow up in a timely manner, so as to ensure the benefits each customer are fully guaranteed, and to provide customers with more value-added services.
