Description:
GB/T 24186 steel is a kind of high strength abrasion resistant steel plates for contrcution machine. There are seven steel grades under this standard: NM300, NM360, NM400, NM450 NM500, NM550, NM600.
Application: NM300 NM360 NM400 NM450 NM500 NM550 NM600 wear abrasion resistant steel plates are widely used in underground mines, cement industry, road construction, mining and open-pit mining and metallurgical industries and manufacturing other wear-resistant parts.

Manufacturing Technique
Cutting large steel plates as your requirements to make the surface of the plate bright by miling and grinding, also can make holes and make angle degrees,and can weld by your drawing.
For the thickness under 30mm, cutting by laser; For thickness over 30mm, mainly OXY-cut, flame cutting.
For the thickness 200mm steel plate, because during the flame cutting, the temperature is very high, so the cutting parts steel plate might be broken at the angle part, then our workers will repair the angles to be good condition.
