How to cut NM400 wear-resistant steel plate?

NM400 wear-resistant steel plate processing: The steel plate cutting method is suitable for cold cutting and hot cutting. Cold cutting includes water jet cutting, shearing, sawing or abrasive cutting. Thermal cutting includes oxygen fuel flame cutting (hereinafter referred to as "flame cutting"), plasma cutting and laser cutting. Cutting method: Through related process tests, master the general characteristics and cutting thickness range of various cutting methods of steel plates. The flame cutting method of NM400 wear-resistant steel is the same as that of ordinary low-carbon and low alloy steel. When cutting thick wear-resistant steel plates, it should be noted that as the thickness and hardness of the steel plate increase, the tendency to crack on the cutting edge increases.
