The market situation of hardox 500 equivalent

HARDOX 500 equivalent, NM400 wear resistant plate is a special structural steel with high wear resistance. Generally speaking, the higher the hardness is, the higher the wear resistance is. The average hardness of NM400 wear resistant plate is 400HB. After quenching, NM400 wear resistant plate has a good martensite bainite microstructure. The addition of Mo, Ni and B alloy ensures the uniform texture in the whole thickness direction.

The hot rolling method is to heat the HARDOX 500 equivalent steel material to about 1000 ℃ ~ 1250 ℃ and use the rolling mill to roll it. The traditional hot rolling process is generally divided into the following two steps: the first step is to use the primary rolling mill or billet rolling mill to roll the ingot, billet or continuous casting billet into a certain shape and size of billet. This kind of HARDOX 500 equivalent rolling process is usually called semi-finished product production, also called blank production.

All steel pipes operated by our company are in compliance with national standards, and the original bill of materials of steel mills is attached. At the same time, we supply the HARDOX 500 equivalent seamless steel pipe, electrical Resistance Weld pipes, large diameter welded pipes ordering business of various specifications and materials and the railway and road transportation business for the majority of users.

Generally speaking, rolled plates are easier to handle in a high temperature environment, and the heat treatment of HARDOX 500 equivalent, rolled plates is also very common. Hot rolling can not only greatly reduce energy consumption and save costs, but also improve the processing performance of metals and alloys, that is, the coarse grains in the as-cast state are broken, the cracks are healed significantly, and the processing performance of the alloy is improved.
