  Induction hardened chrome rods are precision-crafted chromium alloys treated with a magnetic induction process. This technology heats the metal surface to extreme temperatures (up to 1,500°C) and rapidly cools it using a quenching medium. The result? A hardened outer layer (5-8mm thick) with exceptional wear resistance, while the core remains ductile for shock absorption. Key Benefits for Manufacturing Induction Hardened Chrome Rods: ✅ Longer Lifespan: Reduce replacement frequency and labor costs. ✅ Superior Strength: Handle heavy loads and repetitive stress without bending or breaking the raw manterials ✅ Corrosion Resistance: Ideal for automotive, aerospace, and marine industries like hydraulic cylinder applications exposed to harsh environments. ✅ Cost Efficiency: Save up to 40% on maintenance over traditional rods.

  4130 steel , otherwise known as chromium molybdenum steel alloy, is made with 0.8 to 1.1% chromium and 0.15 to 0.25% molybdenum as strengthening agents.Its steel properties make it a versatile metal, especially mechanical properties such as high ductility, good weld-ability, and machi-nability. Equivalent standards of 4130 steel include ASTM A1031 Grade 4130, DIN 1.7214,   25CrMo4 , BS 25CrMo4, EN 1.7214, and UNS G41300. APPLICATIONS OF CHROMOLY (4130 STEEL) 4130 steel rods and tubes are very popular with high strength and great weldability. That's why they are widely used for: Military aircraft Cylinder Shafts Automotive Machine tools Hydraulics barrels 4130 STEEL PROPERTIES Here are the values for some of the main properties of Chromoly: Density – 7.85 g/cm 3 Hardness – 217 (Brinell scale) – 95 (Rockwell B) Ultimate Tensile Strength – 540 MPa Yield Tensile Strength – 460 MPa Modulus of Elasticity – 205 GPa Machinability – 72% (in annealed state) HEAT TREATMENT OF...
