Tips for the flame cutting of wear-resistant plates NM450 and NM500. Guidelines for flame cutting wear-resistant plates NM450 and NM500 (excluding water jet cutting): When performing flame cutting on the finished plates, follow these minimum preheating temperatures: for plates with a thickness of 30 mm or less, the minimum preheating temperature is 100°C; for plates with a thickness of 30–50 mm, it is 150°C; for plates with a thickness of 50–80 mm, it is 170°C. The maximum preheating temperature for all thicknesses is ≤300°C. When using a heat source to cut sheets, preheating and slow cooling should be employed to prevent delayed cracking in the steel plate caused by flame cutting.
