LO-S 3247 Steel

LO-S 3247 Steel

Steel name: LO-S 3247
Diagram No.: 2542
Mat.No. (Wr.Nr.) designation: 1.3247
DIN designation: HS 2-9-1-8
AISI/SAE designation: AISI M42
Chemical composition in weight %: 1.10% C, 4.00% Cr, 9.50% Mo, 1.10% V, 1.50% W, 8.00% Co
Steel group: High speed steels
Properties: High-Speed-Steel with high carbon content on molybdenum base with good grindability due to its low V-content. The high cobalt content installs a good red hardness resp. tempering resistance.
Applications: The steel is mainly used for drills, broaches, milling cutters, circular saw blades, when under working conditions the cutting edges are forced to high temperature loads. In the field of Cold-Work-Steels the grade is used for high loaded thread rolling dies and cold extrusion rams.
Reference: Not shown in this demo version.

Heat Treatment
Hardening: 1160 – 1190 °C, oil /gas-stream /salt bath (550 °C).
Tempering: 540 – 560 °C.
