Laser cutting is that the horizontal laser beam emitted by the laser changes into a vertical downward laser beam through the 45° total reflector, and then focuses through the lens, forming a tiny spot at the focal point. When the spot hits the material, the material is heated to the vaporization temperature quickly, and evaporates to form a hole. With the movement of the beam on the material such as 1.8931 EN 10025-6 high strength steel, the auxiliary gas (carbon dioxide gas, oxygen, Nitrogen, etc.) blow away the melted slag, make the hole continuously form a very narrow width (such as about 0.1mm) cutting seam, and complete the cutting of materials.
S355J2 steel plate belongs to European standard low alloy steel, the executive standard is EN10025-2. Delivery status: normalizing, hot rolling or control rolling. S355J2 corresponds to the Chinese Q345D, but the executive standard is different, the chemical composition is slightly different, but their mechanical properties are the same. S355J2 low alloy steel plate tensile strength (MPA): 450-680, impact value: - 20 ℃: ≥ 27J. 1.8931 EN 10025-6 high strength steel, S355J2 low alloy steel plate is widely used in bridges, vehicles, ships, buildings, steel structures, etc.
In 2010, the 87th session of the International Maritime Organization (IMO) Maritime Committee passed the "Performance Standards for Alternative Anticorrosion Measures for Crude Oil Cargo Tanks". It is mandatory that the cargo tanks of large oil tankers above 5,000 dwt need to be protected or used The construction of corrosion-resistant steel promotes the rapid development of the research and application of corrosion-resistant steel for oil tankers in China. At present, the performance of domestic corrosion-resistant steel has reached the world's leading level and can meet the requirements of large-scale applications.
