The quality of NV D container barge steel shall not only meet the requirements of the standard, but also be higher or stricter than the product characteristics specified in the standard, including chemical composition, structure, physical properties, chemical properties and other requirements of NV D container barge steel buyer, such as packaging, delivery time, etc.. On the basis of the quality of NV D container barge steel in line with the corresponding standards, some buyers will put forward specific requirements according to their own use requirements, which is called technical agreement. That is, some specific factors should be met according to the buyer's requirements.
Shipbuilding steel plates are used to manufacture marine and inland watercraft hulls, requiring high strength, plasticity, toughness, cold bending performance, welding performance, and corrosion resistance. The company provides common shipboard grades such as Grade A, Grade B, Grade D, Grade E, Grade AH32, AH36, AH40, DH32, DH36, DH40, EH32, EH36, EH40, FH32, NV D container barge steel FH36, FH40.
Tempering the important NV D container barge steel welding structure often use high temperature tempering to remove residual weld stress. Classification: high temperature tempering above 400 ℃, medium temperature tempering 250 ~ 400 ℃, low temperature tempering 150 ~ 250 ℃, Quenching +Tempering is improve NV D container barge steel strength, plasticity and toughness.
