Standing at a new historical starting point, we adapt to the requirements of supply side structural reform, adhere to the overall strategy of "innovation driven, quality leading, A131 grade A boat building steel quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the A131 grade A boat building steel International leading steel materials supplier.
Steel materials A131 grade A boat building steel can be classified not only by chemical composition, main quality grade, main performance or use characteristics, but also by habit into carbon steel and alloy steel. Carbon structural steel is easy to smelt, has good processability, low price and large output, and can meet the requirements of common parts of general engineering structure in performance. Carbon structural steel A131 grade A boat building steel is usually rolled into steel plates and various sections, which are used for mechanical parts such as factory buildings and bridges.
EN10083-3 42CrMo4 steel plate delivery status: Heat treatment (normalizing, annealing or high temperature tempering) or non-heat treatment delivery status should be specified in the contract. EN10083-3 42CrMo4 steel plate equivalent materials: JIS SCM440, AISI 4140, GB 42CrMo, A131 grade A boat building steel etc. EN10083-3 42CrMo4 steel plate has high intensity, high hardenability, high fatigue strength and good low-temperature impact toughness.
S355J2 steel plate 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 A131 grade A boat building steel rolling speed is 1.6-2.0m/s, the 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℃.As a basic building material, steel plates are currently widely used in automobiles, shipbuilding, chemical industry, aerospace and other fields. Reasonable selection of flaw detection methods to ensure the quality of A131 grade A boat building steel steel plates is of great significance to safe production. Common defects of steel plates are folding, inclusion, shrinkage, air bubbles, delamination and cracks. These problems can be discovered in time through flaw detection.
