Steel Grade:

SFM-3020 （Similar grades：AISI M2 ESR, HS 6-5-2, JIS SKH51, DIN 1.3343）

Delivery  Status:

Soft-annealed ≤HB260, or ready-made tools, UT qualified.

Material feature:

Super high solidification rate in sprayforming refines the carbide morphology from rough net- works to near-equiaxed, as can be seen from the pictures below, generating better machinability,  more isotropic mechanical properties, e.g. impact toughness increases by 70 - 100%. That means usable hardness of the tools can be increased under the same toughness requirement, thus to  reach much better wear resistance and tooling life than similar grade of ESR.

Applications:

Basic and universal HSS for various cutting tools: drills, reamers, broaches, milling cutters, saw blades, various knives; punching dies, cold work tools, rolls, etc. Due to its high and isotropic strength and toughness, it is specially suitable for heavy load or large tools.

Product  sizes:   

Round bar, up to DIA 300 mm

Rectangular bar:

Microstructures:

          Carbide morphology in DIA 250 mm bars, 100x,     M2 ESR (L), and  SFM-3020 (R).

Remarks: Our expert, inventor of SFM Process, will technically support your applications to best benefits.
