NM500 Hot Rolled Wear Resistant Steel Plate

NM500 hot rolled wear resistant steel plate

一, NM500 steel plate introduction

1, NM500 steel plate is a high-strength wear-resistant steel, NM500 steel plate has high wear resistance, is also a kind of carbon structural steel, belongs to low carbon steel (C ≤0.25%), the chromium content is about 12%. Due to its good hardenability and certain strength and toughness, it is commonly used as a material for gear rack and shaft parts.

2, the NM500 steel plate grade says: N is the first pinyin letter of "resistant" in "wear-resistant". M is the first pinyin letter for "grind" in "wear".500 is the Brinell hardness value HB value. (500 hardness value is a broad sense, the domestic NM500 hardness value is about 500.)

3, NM500 steel plate implementation standard: the implementation of Q/WTB012-2010 standard.

4, NM500 steel plate delivery status: steel plate to tempering (quenching + tempering) state of delivery, can also be specified according to 二, NM500 steel plate chemical composition analysis

Brand: NM500

Thickness: ≤50mm

Carbon: ≤0.38, Silicon: ≤0.70, manganese: ≤1.70, Phosphorus: ≤0.020, sulfur: ≤0.010, Chromium: ≤1.20, molybdenum: ≤0.50, nickel: ≤1.0, boron: ≤0.0005~0.006,

三, NM500 steel mechanical properties:

Brand: NM500

Hardness (HBW) : ≥470, provide steel tensile properties ≥12500, and provide measured values. The elongation after fracture is ≥7%, and the measured value of longitudinal impact (AKV) of the steel plate at -20℃ is ≥24.

PS: The specific mechanical properties should be indicated in the material book of the steel mill.
