The boiler steel plate is used to manufacture various boilers and important accessories. Because the S355J2WP curtain wall steel strip boiler steel plate works under the medium temperature (below 350 ° C) and high pressure state, it is not only subject to high pressure, but also to impact, fatigue load and water and air corrosion. The boiler steel plate is required to ensure certain strength and good welding and cold bending performance.Bridge steel plate S355J2WP curtain wall steel strip is used for large railway bridge. The bridge steel plate is required to bear dynamic load, impact, vibration, corrosion resistance, etc.

With the development of science, technology and industry, higher requirements are put forward for steel materials, such as higher strength, resistance to high temperature, high pressure, low temperature, corrosion resistance, abrasion, and other special physical and chemical properties. S355J2WP curtain wall steel strip, carbon steel can no longer fully meet the requirements, so alloy steel plates appeared. Improving the strength of steel is one of the main purposes of adding alloying elements.

The advantage of plasma cutting is that it can cut thin plates, stainless steel and non-ferrous metals, and the cutting speed is fast. The disadvantage of plasma cutting is that the incision will have a slope, and there will be noise when cutting. The advantages of water jet cutting are wide cutting range and environmental protection, but the disadvantages of water jet cutting are slow cutting speed and high energy consumption. Do you know what is the best cutting method for S355J2WP curtain wall steel strip?
