Hardox 400, NM400 Punched Round Hole Wear Steel Plate Sheet
the follow is compare NM400 and hardox 400. we can do each
material. please think about of it.
NM400 is one kind of Chinese wear/abrasion resistant steel plates,
which is well received in middle east and Africa. An NM400
wear-resistant steel was hot rolled and then the plates were
heat-treated by direct quenching and tempering and reheat quenching
and tempering techniques, respectively. The impact test was carried
out with an instrumented impact tester. The micro-structure and
fracture surface were investigated by a combination of optical
microscopy, transmission electron microscopy and scanning electron
microscopy methods. With high mechanical strength, NM400 is 3 times
to 5 times more than common low-alloy steel plates which can
significantly improve surface hardness, usually achieved 360 ~
The series of NM wear-resistant steel combined the properties
including high strength, high hardness, high wear resistant,
weldable, bendable and mainly applied in:
Edge of loaders in loader industry
Wear-resistant lining plate in crusher industry.
Slat type conveyer in colliery mechanical industry.
Lining plate of coal pulverizer in power industry.
Lining plate of hopper for heavy handling truck.

the follow is prameter of hardox 400 plate:
Hardox 400 is an abrasion-resistant steel with a nominal hardness
of 400 HBW. Hardox 400 is an all-around wear resistant steel.
Thanks to its high toughness, good bendability and weldability,
this steel can be used in structures with moderate wear. Dimension
Range Hardox 400 is available in thicknesses of 4.0 – 130 mm.
Hardox 400 is available in widths up to 3350 mm and lengths up to
14630 mm. More detailed information on dimensions is provided in
the dimension program.
