The density of thickness of steel nm450 sheet structural

According to the European standard EN10025-3:2004, S275NL weldable fine grain structural steel is mainly used to manufacture the plants of factory, the common construction and construction machinery and equipment. For the bound technical terms,steel plate S275NL have to be done low temperature impacting test in rolling process at -50℃ with minimum energy 27J. Other additional requirements such as UT shall be according to EN 10160, and thickness of steel NM450, steel plate S275NL customers can choose the relative classes for Ultrasonic test.

The bridge steel plate is mainly used for erecting railway bridges, highway bridges, sea crossing bridges, etc. The bridge steel plate is required to have high strength and toughness, bear the load and impact of rolling stock, and have good fatigue resistance, certain low temperature toughness and atmospheric corrosion resistance. The bridge steel plate thickness of steel NM450 should also have good welding performance and low notch sensitivity. If you want to have a more comprehensive and detailed understanding of bridge steel plate, welcome to visit our official website for consultation.

As the thickness and hardness of thickness of steel NM450 increase, the tendency to crack at the cutting edge increases. In order to prevent the thickness of steel NM450 from cutting cracks, preheating should be carried out before thickness of steel NM450 cutting. Special attention should be paid to preheating to make the entire thickness of steel NM450 interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole thickness of steel NM450 cannot be preheated, the partial preheating method can be used instead.
