GB YG10 Tungsten Carbide (K30)
Materials encyclopedia entry for YG10.
GB YG10 Tungsten Carbide (K30) is a reference entry for industrial cutting tools and blades. The composition, hardness, heat treatment and application guidance are summarised below for engineering reference.
Standard composition: WC 90 %, Co 10 %, no grain-growth inhibitors, WC grain 1.5–2.0 µm
Hardness: HRA 89.0–90.5 (≈ HRC 76–78)
Heat treatment: Sintered at 1,380–1,460 °C, no further heat treatment
Properties: Standard medium-Co YG10. Higher toughness than YG6 with only slightly lower hardness.
Applications: Medium-impact granulator rotors, shear inserts, wear parts requiring moderate impact resistance.
Cross-reference: ≈ ISO K30, no precise Western equivalent.
