China SKD11 D2 Special Steel Flat Bar Tool Steel Plate

Product Description

SKD11 D2 Special Steel Flat Bar Tool Steel Plate

D2 steel is a high wear resistant micro deformation cold working die steel, belonging to air hardening tool steel. With high quality fraction of carbon and high chronic, the hardness can up to 60HRC after heat treatment, but malleability,toughness,rust resistance is not good and the surface of the steel is also difficult to be polished.

With the development of cold stamping products moving towards high accuracy,high efficiency, varieties, we require the mould steel should has good wear resistance and high toughness.

Compared with Cr12MoV steel, this D2 die steel adds Mo,V compositions,changed the steel cast structure, improved the morphology of ledeburite , toughness and wear resistance are better than Cr12MoV steel, improved the service life as well.Because of the yield point and plastic deformation resistance is higher than Cr12MoV steel, so that forging performance and hot molding properties are a little weak than Cr12MoV steel.

Features

High wear resistance
High compressive strength
Good dimensional stability
Good processability
Excellent resistance to temper softening
Good toughness
