1Cr11Ni2W2MoV: Excellent performance, enabling high-end equipment manufacturing

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.

1. Aerospace: engine compressor blades, turbine discs, shafts and fasteners, subject to tens of thousands of cycle loads.

2. Energy equipment: gas turbine combustion chamber liners, nuclear power plant heat transfer tubes, high temperature and high pressure corrosion resistance.

3. Chemical industry and shipbuilding: pumps, valves, reactor components (non-seawater environment), replacing high-cost nickel-based alloys.

1Cr11Ni2W2MoV, with its balanced combination of high strength, high-temperature resistance, and corrosion resistance, has become a core material for high-end equipment manufacturing. Its electroslag remelting process further ensures its reliability, making it suitable for demanding applications such as aviation, energy, and military. Choosing 1Cr11Ni2W2MoV means choosing the perfect combination of superior performance and long-term stability!
