Aluminum foil rolling mill 35CrNiMo steel sleeve (customized)
| sleeve material | specification |
| 35CrMoV | 665*605*1600 |
Chemical composition of 35CrNiMo (mass percentage)
Execution standards: GB/T 3077-2015 (China), ASTM A434 (American standard)
Range of Element Content (%) Function
Carbon (C) 0.32-0.40 ensures strength and hardness, forming a carbide strengthening phase
Chromium (Cr) 0.60-0.90 improves hardenability, corrosion resistance, and high-temperature strength
Nickel (Ni) 1.40-1.80 significantly improves low-temperature toughness and stabilizes austenite structure
Molybdenum (Mo) 0.15-0.25 suppresses temper brittleness and enhances creep resistance
Manganese (Mn) 0.50-0.80 assists in hardenability and improves thermal processing performance
Silicon (Si) 0.17-0.37 deoxidation to improve strength
Phosphorus (P) ≤ 0.025 impurities (strictly controlled)
Sulfur (S) ≤ 0.025 impurities (affecting thermal brittleness)
Heat treatment process of 35CrNiMo steel sleeve (customized) for aluminum foil rolling mill
Forging: Final forging temperature ≥ 850 ℃, slow cooling after forging (pit cooling or furnace cooling)
Normalization: 880 ± 10 ℃ × 2h, air-cooled
Quenching: 850 ± 10 ℃ oil quenching (cooling rate 80-100 ℃/s)
Cryogenic treatment:- 80 ℃ × 2h (optional, improves dimensional stability)
Tempering: 550 ± 10 ℃ × 4h, water-cooled or oil cooled (to avoid tempering brittleness)
Mechanical processing requirements for customized 35CrNiMo steel sleeve for aluminum foil rolling mill
Dimensional tolerance:
Inner/outer diameter: IT6 grade (≤ 0.02mm)
Cylindricity: ≤ 0.005mm
Surface roughness: Ra ≤ 0.8 μ m (mating surface requires Ra ≤ 0.4 μ m)
Residual stress control: Stress relief annealing (300 ℃ × 4h) is required after machining
