The purpose of quenching is to improve the hardness, strength and wear resistance of EN10025-5 S235J2W steel plate, and give full play to the performance potential of EN10025-5 S235J2W steel plate. However, quenched martensite is not the final structure r
Low and medium carbon steel and EN10155 S355J0W weathering steel plate are normalized to improve cutting performance. As the production cycle of EN10155 S355J0W weathering steel plate normalizing is shorter than annealing and the operation is convenient,
In the flame cutting process of EN10155 S355J0W weathering steel plate, the height of the cutting nozzle to the working surface is one of the main factors that determine the cutting quality and cutting speed. When using cutting nozzles with different para
Ni: nickel is also one of the elements to improve the weather resistance of ASTM A588 grade B steel plate, which can promote the formation of stable rust layer and also improve the welding performance of ASTM A588 grade B steel plate. However, too much ni
Manganese is the necessary element for deoxidation in the process of making ASTM A588 gr. C steel plate. The strength of ASTM A588 gr. C steel plate can also be improved by solution strengthening. In order to achieve enough high tensile strength, the mang
EN10025-5 S355J2WP weathering steel plate is designed with low carbon composition. The high carbon content is unfavorable to the impact toughness of steel, especially the impact energy of EN10025-5 S355J2WP weathering steel plate, and obviously damages th
Cu: copper can promote the formation of stable and dense rust layer on the surface of ASTM A242 type1 weathering steel plate, and also improve the weather resistance of ASTM A242 type1 weather resistant steel plate. However, the high copper content will c
Q355NH weathering steel plate must undergo a quenching process in the manufacturing process. Sometimes, due to poor workmanship, Q355NH weathering steel is often deformed due to too high and too low heat.
The cutting speed has a parabolic relationship with the cut surface roughness of A 709 Grade 50W weathering steel plate. As the cutting speed decreases, the surface roughness of A 709 Grade 50W weathering steel plate increases rapidly. With the increase o
When the rolling thickness of ASTM Corten A steel plate is more than 10 mm in the rolling pit, after the wear-resistant liner bites into the rolling mill, the splint should be opened quickly to reduce the friction between the splint and the bimetallic AST
