GB/T24186NM450 abrasion resistant plate specification and application
GB/T24186NM450 abrasion resistant plate is a wear-resistant steel plate with high hardness. These are highly required in the manufacturing industry. When applied to the reduction environment, these are outstanding for the reduction environment due to its corrosion resistance.
GB/T24186NM450 abrasion resistant plate has good weldability and good corrosion resistance. This reduces high performance in the environment even at high temperatures. This grade is both magnetic and nonmagnetic in nature. When the temperature increases,GB/T24186NM450 abrasion resistant plate can resist the deformation of impact load. These are completely austenite in nature.
