The difference between alloy steel plate and carbon steel has the following points. First, the hardenability of carbon steel is low, and the maximum diameter of water quenching of carbon steel is only 10 mm to 20 mm; second, the strength of carbon steel is only 235 MPa, while that of alloy steel is more than 360 MPa. Third, carbon steel has poor tempering stability. In order to ensure high strength, low tempering is used for carbon steel during quenching and tempering treatment, so the toughness of the carbon steel is insufficient. Fourth, the corrosion resistance, low heat resistance, and wear resistance of carbon steel cannot be compared with alloy steel, NM450 plate impact resistance.

Spring steel has good fatigue strength and can be restored to its original shape after repeated use without deformation. Because the spring has good ductility, it can be changed back to its original state no matter how long it is stretched. Spring steel has good elasticity. In addition to being made into springs, spring steel can also be processed into swords, which requires good elasticity also. NM450 plate impact resistance, Spring steel has good tensile strength and can be restored without breaking under the limit of being stretched.

Flame cutting uses the high temperature generated during the combustion of iron oxide to cut carbon steel NM450 plate impact resistance. The design of the flame cutting torch provides sufficient oxygen for burning iron oxide to ensure a good cutting effect. The CNC flame cutting machine is a mechanical equipment mainly suitable for the cutting of medium and thick plates. Compared with other similar thermal cutting methods, the CNC flame cutting machine has the characteristics of high cutting quality, good cutting surface perpendicularity, and large cutting thickness.
