NM450 Steel

NM450 steel

The use of wear-resistant steel:

1. Cutting: can be used equal cut, carbon arc, grinding wheel saw.

The best method is to cut with sub-arcs such as air or inert gas, generally starting from the alloy surface. Carbon arc cutting should start from the fundamentals, one side of the substrate, if the saw blade is used, it can only be cut in a straight line, and silicon carbide saw blades should be used.

Bending: The wear-resistant steel plate can be cold-processed and bent into the desired shape

Or arc or round, concave molding, alloy crack due to the internal stress, will be closed convex molding, crack will become larger cracking, this is a normal phenomenon, if the cracking is too large, use the corresponding welding rod to repair. Coil the tube to the recommended minimum bending radius.

3. Opening: plasma cutting can be used for large holes, and EDM machine tools are recommended for small holes. The countersunk holes for bolt assembly can be cut by plasma or carbon arc

4. Welding: The base material of the large-area composite steel plate is a weldable steel plate with good performance. When the two steel plates are joined together, the base material on the back side can be welded together first, and then the positive surfacing welding surface can be filled with the corresponding surfacing electrode. Wear-resistant steel plates can be welded to their other steel plates.

5. Plug welding:

Use plasma or carbon arc gouging to cut holes in the wear-resistant steel and connect with other steel structural parts by plug welding.

6. Screw gun fixation:

Bolts can be welded to the base metal of the steel plate by flash welding or melt welding, and then connected to other workpieces, or holes can be opened in the steel plate and connected to other workpieces by butterfly plugs.
