Store cemented carbide products in dry environments (<40% RH) with anti-rust desiccant, and avoid direct contact with ferrous metals to prevent galvanic corrosion on cemented carbide or tungsten steel surfaces. Use shock-absorbent packaging (e.g., foam-lined boxes) for precision-ground edges, and segregate by hardness grades (e.g., K10/K20) to avoid edge chipping during handling.
