The alloy 00Cr17Ni14Mo2 is a nickel-chromium stainless steel, commonly used in high-temperature and high-pressure environments. It is a maraging steel (also known as martensitic stainless steel), known for its high strength, toughness, and corrosion resistance.
Composition (by weight):
- Carbon (C): 0.004%–0.02%
- Chromium (Cr): 17%–19%
- Nickel (Ni): 14%–16%
- Molybdenum (Mo): 2%–2.5%
- Other elements: Trace amounts of sulfur, phosphorus, and other elements
Properties:
- High strength and hardness (up to 1,200–1,500 MPa)
- Good toughness and impact resistance
- Excellent corrosion resistance (especially to acids, salts, and atmospheric corrosion)
- High melting point (around 1,450°C)
- Good thermal stability and resistance to thermal stress
- Suitable for high-temperature applications (up to 1,200°C)
Applications:
- High-strength structural components in power plants, chemical plants, and aerospace
- Pressure vessels and heat exchangers
- Boiler tubes and furnace components
- High-temperature turbine blades
- Welded components in harsh environments
Standard:
- ASTM A240 (for pressure vessels)
- ASTM A48 (for high-strength steel)
- ASTM A533 (for structural steel)
- ISO 14230 (for high-temperature steels)
Notes:
- The 00Cr17Ni14Mo2 is a low-carbon stainless steel with a high chromium content (17%).
- It is often used in marine and chemical environments due to its corrosion resistance.
- It is not suitable for high-temperature environments beyond 1,200°C, but can be used in high-temperature applications with proper heat treatment.
Heat Treatment:
- For structural applications: Quenching and tempering (e.g., 550–600°C)
- For high-temperature applications: Tempering at higher temperatures (e.g., 800–900°C)
