Delamination damage of S690Q steel

45# seamless steel pipe (No.45 seamless steel pipe) is Chinese high-quality carbon structural steel, which is called S45C in Japanese standard, AISI 1045 in American standard, and C45 in German standard. The difference between 45# seamless steel pipe and 20# seamless steel pipe is that its hardness is obviously higher than that of 20# seamless steel pipe. The tempering brittleness of S690Q steel, 45# seamless steel pipe is high. After quenching and tempering, 45# seamless steel pipe has good mechanical properties. If the wear resistance is considered, heat treatment is required.

Compared with carbon steel, low alloy steel has many advantages, such as high strength, good plasticity and toughness, good weldability, good cold and hot pressure processing performance, better corrosion resistance, etc. Due to the increase of S690Q steel metal composition, the yield point of low alloy steel structure is higher than that of ordinary carbon steel, so it is light and suitable for structural parts application. The low alloy steel is one of our main products.

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 S690Q steel?
