N400 (1.2767) Steel

Steel name: N400 (1.2767)
Diagram No.: 2512
Mat.No. (Wr.Nr.) designation: 1.2767
DIN designation: 45NiCrMo16
Chemical composition in weight %: 0.45% C, 0.25% Si, 0.40% Mn, 1.35% Cr, 0.25% Mo, 4.00% Ni
Steel group: Cold work tool steels
Properties: N400 is characterized by its high Ni content as a tough cold-work tool steel with high hardenability. N400 shows good polishability and texturing properties as well as good through hardenability.
Applications: Cutlery punching, shear blades for thick goods above 12 mm. Scrap and billet shear blades. Embossing and bending tools for heavy cold forming. Drawing jaws, large lathe punches and similar tools, which demand maximum toughness. Shrink rings, tempered as required to a strength of 1300-1600 MPa. Plastic molds.
Reference: Not shown in this demo version.

Heat Treatment
Hardening: 840 - 870 °C. Air, warm bath from 180 - 220 °C or oil, interrupt oil cooling at approx. 150 °C.
Tempering: 100 - 400 °C.
