CCS grade A ferries steel material grade comparison

CCS grade A ferries steel,20# steel plate is a high-quality low-carbon carbon steel plate, cold extruded, carburized and hardened steel. CCS grade A ferries steel, 20# steel has low strength, good toughness, plasticity and weldability The tensile strength is 253-500MPa, and the elongation is ≥24% 20# steel performance is basically similar to 15# steel, but the strength is slightly higher The cold-drawing or normalizing state of the cutting process is better than the annealing state 20# steel is used to manufacture various mechanical parts with high toughness under hot rolling or normalizing state, which require high toughness,CCS grade A ferries steel.The company adheres to the management concept of "people-oriented, talent is concerned", develops business with the spirit of "believing strength, practical style, 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 tomorrow!
CCS grade A ferries steelS355J2 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 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 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.
For wear-resistant steel plate, it is not the higher the hardness, the better the wear resistance! Hardness is the basis of excellent wear resistance of wear-resistant steel plate, but the relationship between hardness and wear resistance is not in direct proportion. The reason why wear-resistant steel plates are wear-resistant is that they have hard particles and soft matrix. Generally, in the process of wear, there will be some falling substances, which will be incorporated into the soft matrix and will not cause great damage to the surface.
