Let's seize the day and live it to the full, and greet the arrival of the year 2020 together.
Material common grades: Q235B,Q345B, AB EH32, AB DH36, AB EH36, RE 40 marine grade ship steel plate, CCS-A, CCS-B,CCSA, CCSB, CCS,CCSD, CCSE. Carbon structural steel plates and sheets are mainly used in the manufacturing of mechanical parts with complex shapes and high requirements for mechanical properties, but it is difficult to shape them by forging and pressing in the process, such as the gearbox shell of the automobile, the coupler and coupling of the locomotive and vehicle.
In the second step of hot rolling process, different finished mills are used to roll billets or continuous casting billets into finished steel of proper shape and size. This RE 40 marine grade ship steel plate production process is called finished product production, which is generally divided into two stages of rough rolling and finish rolling. In the roughing stage, a large amount of reduction (reduction per pass) is adopted to reduce the number of passes and improve the output; after roughing, the finishing stage is entered, and the finishing is carried out with a small amount of reduction to achieve a good surface and accurate RE 40 marine grade ship steel plate size.
What is the difference between Q345B steel and Q345A steel? RE 40 marine grade ship steel plate, Q345B steel and Q345A steel have slight difference in chemical composition: Q345A steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.045, S ≤ 0.045, V 0.02 ~ 0.15; Q345B steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.040, S ≤ 0.040, V 0.02 ~ 0.15. The difference between Q345B steel and Q345A steel is mainly in A and B behind the steel grade, Q345A steel grade is not subject to impact; Q345B steel grade needs 20 ℃ room temperature impact test.
Our company's logistics breaks through the perspective that the center of transportation service is ability, and emphasizes that the purpose of transportation service is customer first. Customer demand determines the content and mode of transportation service, while production is often small batch, diversified and consumer demand tends to be diversified. In the case of personalization, our logistics service also provides personalized service projects.
The company will rely on its good reputation, excellent hot-rolled plates, steel pipes, steel structure products, and intimate RE 40 marine grade ship steel plate after-sales service to customers.
