Description
Grinding Rod 34CrNiMo6 Kiln Support Roller Casting Alloy Steel Round Bar
Alloy Material Grade 34CrNiMo6 DIN1.6582 EN 10083-3 alloy steel bar manufactured according to ASTM standards. This high-strength nickel-molybdenum alloy steel offers excellent comprehensive mechanical properties for demanding industrial applications.
Grade 34CrNiMo6 DIN1.6582
Application Widely used in fasteners, chains, kitchen and sanitary wares, furniture handles, handrails, electroplating equipment, food processing, electronics, petroleum, construction, and decorative applications with high strength after cold-drawing, anti-stress corrosion, and excellent surface quality.
Chemical Composition Manufactured according to international standards including ASTM, AISI, JIS, ER, GB
DIN 34CrNiMo6/1.6582 alloy steel is supplied as forged round bars, square/flat bars, rollers, shafts, and blocks, or as rolled round rods. This high-strength steel is commonly used in engine camshafts and connecting rods, though it has poor processability and is considered a difficult-to-machine material.

Applications
34CrNiMo6 steel is used in high-load shaft applications such as connecting rod structures. DIN 1.6582 steel is also used for surface-hardened wear-resistant and flexible components like gears, as well as engine camshafts and connecting rod parts.
Forging Process
  • Preheat 1.6582 forged alloy steel carefully
  • Raise forging temperature to 1150-1200°C
  • Maintain forging temperature above 850°C
Heat Treatment
Hardening & Tempering
  • Heat uniformly to 850°C
  • Quench in oil
  • Heat to 550°C
  • Soak for at least 2 hours
  • Cool in furnace
After QT, if straightening is necessary, temper and distortion-poor anneal at minimum 625°C.
Annealing
  • Heat thoroughly to 800-850°C
  • Cool slowly to 550°C
  • Complete annealing in air
Normalizing
  • Heat until temperature reaches 850°C
  • Cool to room temperature in air
