High Quality Wholesales GB NM500 Hot Forged Carbon Tool steel Plate
1: GB NM500 steel introduction
The NM 500 is a flexible and welded wear plate for applications where wear resistance is more demanding. It is also a wear-resistant steel plate with an average hardness of 550 HBW, which is used in high wear situations. It is intended primarily for users and manufacturers using high manganese steel castings or 500 Brinell hardness wear resistant steel plates when upgrading from 500 steel plates to this product. The Brinell hardness is increased by 50 units and the wear life is prolonged without loss of the toughness of the steel plate.

We are professional manufacturer for many years. we can provide a wide range of steel products.
Usually bundling for large diameter,small diameter bars in bulk or as customer's demand.
The hardness after heat treatment is higher than D2/1.2379/Cr12Mo1V1, and can reach 61-63HRC after high-temperature tempering (525 ± 5 ℃); In terms of strength and wear resistance, it exceeds Cr12Mo1V1, and its toughness is higher than D2/1.2379/Cr12Mo1V1; The manufactured molds rarely have cracks and fissures, greatly improving their service life; The residual stress after wire cutting processing is smaller than that of Cr12Mo1V1; The cutting and grinding performance exceeds Cr12Mo1V1.
Suitable for manufacturing precision punching dies and stamping dies for cold forging, deep drawing, and wire rolling for wire cutting processing.
