US (1.2606) Steel

Steel name: US (1.2606)
Diagram No.: 2493
Mat.No. (Wr.Nr.) designation: 1.2606
DIN designation: X37CrMoW5-1
Chemical composition in weight %: 0.36% C, 1.00% Si, 0.40% Mn, 5.20% Cr, 1.40% Mo, 0.30% V, 1.40% W
Steel group: Hot work tool steels
Properties: US corresponds to the steel USN with additional W-content. This increases the high-temperature strength and hot wear resistance. Hot toughness and thermal shock resistance are good. Water-coolability is limited.
Applications: Molding press die of heavy and light metal processing. Forging tools such as small and medium full dies in forging presses. Die inserts, mandrels, forging dies and punches in steel processing.
Reference: Not shown in this demo version.

Heat Treatment
Hardening: 1000 - 1050 °C. In Air, warm bath of approx. 540 °C, Oil/polymer; Interrupt oil or polymer cooling at 230 - 280 °C or vacuum hardening.
Tempering: 520 - 700 °C.
