Steel Grade:

SFM-3040 （Similar grades：AISI M4 ESR, HS 6-5-4, JIS SKH54, DIN 1.3395）

Delivery  Status:

Soft-annealed ≤HB280, or ready-made tools, UT qualified.

Material feature:

Super high solidification rate in sprayforming makes the microstructure very fine and homoge- neous. High-alloyed, especially high V-alloyed carbides and nitrides in microns are spheroidal,  uniformly distributed in the matrix, facilitating excellent red-hardness, isotropic mechanical pro- perties, e.g. impact  toughness is increased by 70 - 100%, and good machinability, better wear resistance and tooling life comparing to similar grade of ESR or even PM steel.   

Applications:

High-V-alloyed high speed steel for universal applications, such as various cutting tools, punch dies, broach inserts, metal forming 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 a sample of DIA 200 mm bar, 100x (L) & 500x (R)
