Product Introduction

Nm450 Wear Resistant Steel Sheet Plate

NM450 wear-resistant steel plate is widely used in engineering machinery, mining machinery, coal mining machinery, environmental protection machinery, metallurgical machinery, abrasive tools, bearings and other product parts.

Surface processing:

The surface of wear-resistant steel does not need to be processed, if it needs to be processed, it is only surface grinding, and wear-resistant steel is not suitable for occasions with high surface accuracy.

Chemical composition: C 2%, Si2%, Mn2%, P0.02%, S0.02, Ai3%, Ti3%, B4%, N3%, Ni2%, Cr2%, Mb25%

Tensile test: yield 1119MPa, tensile 1255MPa, elongation 13%EL.

Impact power test: temperature -20 degrees, direction: L, impact power: 58 hardness 438HWC.
