Wear Plates
Wear-resistant steel is widely used in mining machinery, coal mining operation, construction machinery, agricultural machinery, building materials, electrical machinery, rail transportation sector. For example, the ball of the ball, lining, excavator bucket teeth, bucket, all kinds of breakers rolling acetabular wall, tooth plate, hammer, crawler tractors and tanks, plates, fans blow plate mill, rail frog fork, coal conveyor plate with the middle slot, slot to help, ring chain, with bulldozers, shovel, shovel teeth, large electric wheeled bucket with liner, oil and iron ore open with a rock bit more punch .

All kinds of machinery in the relative motion of the workpiece to ask, will produce all types of wear and tear, will have to improve wear resistance of the workpiece material requirements or require the use of wear-resistant steel.

NM360 Introduction

Range: fall wear plate (wear plate) series.


Call method: wear three hundred and sixty.


Name: N is the resistance (nai) M is the mill (mo) of two Chinese characters of the first phonetic alphabet, 360 represents the average Brinell hardness of this steel


Heat treatment: tempering, quenching and tempering (quenching and tempering)


Applications: NM360 wear plate is widely used mining machinery, mining machinery, environmental protection machinery, engineering machinery, also used as the yield strength ≥ 700MPa high strength structural steel.


Role: mainly in the need to wear the occasion or location to provide protection to the equipment, longer life, reduced maintenance downtime caused by maintenance, the corresponding reduction in capital investments.


Performance: yield in more than 800, the tension in the 1000.

NM360 test
Test each batch of steel items, the number of samples, sampling methods and test methods should meet the requirements are consistent with the following table:

Test item serial number of sampling test methods for sampling
1 drawing 1 GB/T2975 GB/T228
2 Impact 3 GB/T2975 GB/T229
3 bending test 1 GB/T2975 GB/T232
4 Hardness 1 GB/T2975 GB/T231

Brinell hardness (HBW) test, based on national standards GB/T231, steel milling off the surface of 1.0-2.2 mm, and then test the hardness of this surface.
