The company adheres to the management concept of "people-oriented, talent is concerned", develops business with the spirit of "believing strength, practical style, hull of ships use CCS DH40 plate professional service and dare to compete", and provides customers with "professional, value-added and effective" service support. For the company's development and take-off, we work together to move forward and create a better hull of ships use CCS DH40 plate tomorrow!
The company has strict control on the quality of hull of ships use CCS DH40 plate. Each hull of ships use CCS DH40 plate is inspected for the whole process, including raw material purchase, production process according to the procedures and relevant regulations. According to the technical standards and technical requirements, the composite quality inspection is carried out to confirm whether the hull of ships use CCS DH40 plate meets the specified quality requirements. If the hull of ships use CCS DH40 plate does not meet the quality requirements, the non conformity control shall be implemented, and the unqualified hull of ships use CCS DH40 plate shall be removed, marked, registered and effectively isolated; the hull of ships use CCS DH40 plate shall be inspected and confirmed for acceptance, release and delivery, and the quality certificate shall be issued.
The cold working performance of hull of ships use CCS DH40 plate 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 hull of ships use CCS DH40 plate 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.
The characteristic of niobium in hull of ships use CCS DH40 plate etc. steel material is to increase the recrystallization temperature of austenite, so as to achieve the purpose of refining austenite grains. In general, the amount of niobium added in steel material is less than 0.05%, and the contribution of niobium above 0.05% to strengthening and toughening will no longer be obvious.
S355J2 steel plate belongs to European standard low alloy steel, the executive standard is EN10025-2. Delivery status: normalizing, hot rolling or control rolling. S355J2 corresponds to the Chinese Q345D, but the executive standard is different, the chemical composition is slightly different, but their mechanical properties are the same. S355J2 low alloy steel plate tensile strength (MPA): 450-680, impact value: - 20 ℃: ≥ 27J. hull of ships use CCS DH40 plate, S355J2 low alloy steel plate is widely used in bridges, vehicles, ships, buildings, steel structures, etc.
