Why Clients Choose YUTONG’s Quenching Tempering Rods

Quenching and tempering is a heat treatment process that transforms ordinary steel into high-performance alloy rods. Here’s how we ensure every rod meets exacting standards: 1. Material Selection & Preparation High-Purity Alloy Steel: We use grades like 4140 hard chrome rod , 4340 chrome plated bar, or custom alloys tailored to client specifications, ensuring optimal carbon content (0.35–0.50%) and traceability. Precision Forging: Rods are hot-forged to refine grain structure, eliminating voids and ensuring uniform mechanical properties. 2. Controlled Quenching Process Induction Heating: Rapid, uniform heating to 850–950°C (depending on alloy) in inert atmospheres prevents decarburization. High-Speed Quenching: Oil, polymer, or water quenching achieves a hardened martensitic structure with minimal distortion. 3. Precision Tempering Stress Relief: Tempering at 400–600°C restores ductility while maintaining hardness (typical range: 28–32 HRC to 45–50 HRC). Multi-Stage Tempering:...
