| Tensile and impact requirements | Specify separately if the part requires them. The cited BEBON row gives no values for these tests. |
| Workshop operations | Confirm hole preparation, cutting and forming requirements before release. |
Ordering and inspection
| Parameter / condition | Value / requirement |
|---|---|
| Dimensions and quantity | Specify thickness × width × length, pieces or total mass. |
| Certificate and traceability | State the inspection document required and link each plate to its heat number. |
The stated values use the rule edition shown above. Select the contract standard, thickness, delivery condition and test specimen together; the supplied plate certificate records the actual heat results.
Where this plate fits
Where ore or aggregate slides over a replaceable liner, hardness is one of the purchasing checks. A chute that takes repeated drops also needs an impact review. Share the feed size and drop height if the drawing leaves the grade open.
Before requesting a quote
For drilled liners, specify the hole pattern, countersinks, edge distances and the final part geometry. Ask how the mill measures hardness and request the agreed results in the inspection documents.
Frequently asked questions
Can NM500 replace NM400 in every liner?
Compare the wear mechanism, impact load and forming needs before changing the grade. Ask the equipment owner to approve the change.
