NM450 abrasion resistant steel
steel Product Introduction
NM450 flame cutting and welding:
Flame cutting should follow the following minimum preheating temperatures: 75°C for plate thicknesses of 25 to 75mm, and 125°C for plate thicknesses above 70mm. Alkaline-coated electrodes with low residual moisture should be used for manual arc welding. When necessary, drying should be carried out according to the requirements of the electrode manufacturer. In addition, the following suggestions should also be considered: Generally speaking, steel plates with a thickness of less than 15mm are not suitable for welding. Requires preheating. In order to prevent weld cracking when the structural rigidity is high, it is generally recommended to adopt a preheating temperature of 105~150℃ for steel plates thicker than 15mm. Preheating above 200°C must be avoided as it will reduce hardness.
