STF4M Steel

STF4M Steel

Steel name: STF4M
Diagram No.: 1620
Chemical composition in weight %: 0.45-0.60% C, max. 0.40% Si, 0.60-1.10% Mn, 0.70-1.70% Cr, 1.30-2.50% Ni, 0.40-1.00% Mo
Steel group: Forging die tool steels
Properties: Chemical compositions are adjusted to meet a specific size of tool block, and the hardness is controlled uniformly throughout the tool block, regardless of its size. Even after re-sinking, the block can be used under the same conditions as before, and extended service life is assured.
Applications: No data
Reference: Not shown in this demo version.
