low temperature ocean steel ABS FH40, 45Mn2 steel is a kind of alloy structural steel. 45Mn2 steel is made of high-quality carbon structural steel with proper addition of manganese. 45Mn2 steel belongs to the medium carbon quenched and tempered steel in alloy structural steel. The parts made with 45Mn2 steel can obtain high strength and good toughness after quenching and tempering at high temperature. That is to say, 45Mn2 steel has good comprehensive mechanical properties and is often used to manufacture shafts, connecting rods, fasteners which bear large loads.
We have 4 typical production lines, which can produce hot rolled Seamless, LSAW, ERW and SSAW pipes. SSAW pipe production line range is OD 219.1mm-3500mm, wall thickness 3.2mm-25.4mm. Product low temperature ocean steel ABS FH40 annual capacity is 200 thousand tons.
S355J2 steel plate low temperature ocean steel ABS FH40 rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the rolling speed is 1.6-2.0m/s, the low temperature ocean steel ABS FH40 single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.
low temperature ocean steel ABS FH40, Q345R pressure vessel steel is an ordinary low alloy steel, which is commonly used for boiler and pressure vessels. The delivery status of Q345R pressure vessel steel is hot rolling or normalizing. The properties of Q345R pressure vessel steel are similar to those of Q345 steel (16Mn). The yield strength of 16mm steel plate is greater than 345 Mpa, the tensile strength is 510-640 Mpa, the elongation is more than 21%, and the zero degree V-shaped impact energy is greater than 34J. The process reference standard of Q345R pressure vessel steel is GB713.
We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
