Insert GradesCoate dCarbideCermetCarbideCBNPCDCeramic Grade Carbide IGETALLOY cemented carbides have a solid history and a wide variety of grades to suit many different applications. They are widely used and appreciated for their superior performance. The IGETALLOY range consists of cemented carbide grades with various characteristics that correspond to the cutting tool application. This is achieved by varying the carbide components: the WC structure (main component) and additives such as TiC, TaC, and Co (binder). The wide selection of IGETALLOY grades provides excellent wear resistance and toughness in various cutting conditions. ● For Steel ● For Stainless Steel ● For Cast Iron A30N EH510 H10E A Characteristic Values Work Material Grade Hardness (HRA) TRS (GPa) Thermal Conductivity (W/m·°C) Young Modulus (GPa) Compressive Strength (GPa) Linear-Thermal Expansion Coefficient (x 10-6/°C) ST10P 92.1 1.9 25 470 4.9 6.2 ST20E 91.8 1.9 42 550 4.8 5.2 A30 91.3 2.1 35 520 — 5.2 Steel A30N 91.2 2.2 35 520 — — ST40E 90.4 2.6 75 — — — EH510 92.6 2.6 76 — — — EH520 91.7 3.0 78 — — — Stainless Steel A30 91.3 2.1 35 520 — 5.2 A30N 91.0 2.4 35 — — — BL130 94.3 2.9 56 — — — H2 93.2 1.8 105 600 6.1 4.4 H1 92.9 2.1 109 650 6.1 4.7 EH510 92.6 2.6 76 — — — Cast Iron H10E 92.3 2.0 67 — — — EH520 91.7 3.0 78 — — — G10E 91.1 2.2 105 620 5.7 — H1 92.9 2.1 109 650 6.1 4.7 Non-Ferrous Metal H20 91.6 3.8 — — — — EH510 92.6 2.6 76 — — — Exotic Alloy EH520 91.7 3.0 78 — — — A30
