KSV (1.2838) Steel

KSV (1.2838) Steel

Steel name: KSV (1.2838)
Diagram No.: 2513
Mat.No. (Wr.Nr.) designation: 1.2838
DIN designation: 145V33
Chemical composition in weight %: 1.45% C, 0.30% Si, 0.40% Mn, 3.25% V
Steel group: Cold work tool steels
Properties: KSV is a water-hardenable steel (surface-hardening). The V content ensures lack of sensitivity to overheating and also a high wear resistance with a tough core. The hardness penetration depth of KSV can be increased considerably with increasing hardening temperature.
Applications: Cold impact tools of all kinds, such as head stamps, first and second punches, dies in screw and rivet manufacturing. Impact seams of flat etchers and similar tools. Cold extrusion tools. Drawing dies for rod drawing (hardening of the hole).
Reference: Not shown in this demo version.

Heat Treatment
Hardening: 800 - 950 °C. Water, interrupt water hardening at approx. 120 °C, further cooling in oil.
Tempering: 100 - 300 °C.
