HMoD (1.2889) Steel

HMoD (1.2889) Steel

Steel name: HMoD (1.2889)
Diagram No.: 2499
Mat.No. (Wr.Nr.) designation: 1.2889
DIN designation: X45CoCrMoV5-5-3
Chemical composition in weight %: 0.45% C, 0.30% Si, 0.40% Mn, 4.50% Cr, 3.00% Mo, 2.00% V, 4.50% Co
Steel group: Hot work tool steels
Properties: Due to its composition, HMoD is a hot-work tool steel with very high high-temperature strength and tempering resistance with high hot wear resistance.
Applications: Extrusion dies for brass. Die settings in heavy metal processing. Die casting dies for casting heavy metals and relatively thin-walled cast pieces. Highly stressed cores located in the casting stream when casting light metals. Molding press dies, especially mandrel inserts in the hot pressing of heavy metals. Small die inserts and hot extrusion dies in steel forming. Heated die inserts for hot-stamping.
Reference: Not shown in this demo version.

Heat Treatment
Hardening: 1120 - 1150 °C. Air, warm bath of approx. 540 °C oder Oil/polymer; Interrupt oil or polymer cooling at 250 - 300 °C or vacuum hardening.
Tempering: 580 - 750 °C.
