Properties of EN steel grade S275NL material

EN steel grade S275NL material,The seamless carbon steel pipe for ships (gb5213-85) is the seamless carbon steel pipe for the manufacture of class I pressure pipe system, class II pressure pipe system, boiler and Superheater of ships. . The working temperature of carbon steel seamless pipe wall shall not exceed 450 ℃, and that of alloy steel seamless pipe wall shall exceed 450 ℃.

Bridge steel is required to have higher strength, toughness, load and impact of rolling stock, and good fatigue resistance, low temperature toughness and atmospheric corrosion resistance. With the development of domestic railway construction towards high speed and heavy load, railway bridge steel developing in the direction of high speed, heavy load, long span, beautiful and novel structure, and full welding, higher requirements are imposed on the properties of steel for bridges. In particular, the development of cross-sea bridges has put forward higher requirements on the corrosion resistance of steel for bridges.

As the thickness and hardness of increase, the tendency to crack at the cutting edge increases. In order to prevent the EN steel grade S275NL material from cutting cracks, preheating should be carried out before cutting. Special attention should be paid to preheating to make the entire EN steel grade S275NL material interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole EN steel grade S275NL material cannot be preheated, the partial preheating method can be used instead.
