1Cr11Ni2W2MoV: China Suppliers & Factory for High-Performance Heat-Resistant Stainless Steel in Aerospace Manufacturing
Core Features
1. Excellent high temperature strength and toughness
It can maintain high strength and stability in an environment below 600°C, with a room temperature tensile strength of 885–1080 MPa, a yield strength of 735–885 MPa, and an elongation of 12%–15%.
Tungsten (W) and molybdenum (Mo) elements strengthen and refine grains through solid solution, while vanadium (V) microalloying inhibits high-temperature creep, ensuring that the material still has a high fatigue life under thermal cycling stress.
2. Excellent corrosion resistance and oxidation resistance
The high chromium content (10.50%–12.00%) forms a dense Cr₂O₃ oxide film that is resistant to fresh water, wet atmosphere, and weak acid and alkali corrosion.
It is "completely resistant to oxidation" (oxidation weight gain rate <0.1 g/m²·h) in air at 700°C and is suitable for high-temperature oxidation environments.
3. Optimized process performance
The electroslag remelting process ensures extremely low impurity content (S≤0.025%, P≤0.030), improving material purity and lateral mechanical properties.
It supports welding (TIG/MIG), forging and machining, and its annealed hardness ranges from HB 197 to 269, making it easy to form complex components.
4. Flexible heat treatment adaptability
Performance customization can be achieved through differentiated tempering systems:
High toughness requirement: Tempering at 660–710°C → impact energy ≥ 71 J, hardness HB 269–321.
High strength requirements: Tempering at 540–590°C → tensile strength ≥1080 MPa, hardness HB 311–388.
