NM400 NM450 NM500 Steel Plate
NM400
steel is a high-strength, wear-resistant steel known for its superior strength
and rigidity. NM400 is a Chinese GB standard steel grade. NM 400 is widely used
in industries where abrasion resistance is important, such as construction and
mining.
NM450
is a wear-resistant steel sheet with a hardness of 450 HBW. NM450
wear-resistant steel sheet has very good weldability. N -
"wear-resistant" in the "resistance" of the first phonetic
alphabet. M is "wear-resistant" in the "grinding" of the
first phonetic alphabet.450 Brinell hardness HB value. (450 hardness is wide,
domestic NM450 hardness value is about 450).
NM500
steel is one of the steel grades in the GB 24186 standard. NM 500 steel is a
high strength, wear/abrasion resistant steel known for its superior hardness
and durability. This steel is specially designed to withstand high wear
conditions and provide long service life in harsh environments.
