Description
Alloy Geek M152 nickel-chromium Standard
Alloy M152, also known as UNS N06252, is a nickel-chromium alloy with additions of molybdenum and tungsten. It is designed to offer a combination of high-temperature strength, excellent corrosion resistance, and good oxidation resistance. Alloy M152 is commonly used in applications that involve extreme temperatures and aggressive environments.
The composition of Alloy M152 typically includes:
- Nickel (about 58-62%)
- Chromium (about 20-24%)
- Molybdenum (about 8-10%)
- Tungsten (about 2.5-3.5%)
- Iron (about 2.0% max)
- Cobalt (about 2.0% max)
- Small amounts of other elements like carbon, silicon, and manganese
Key features and characteristics of Alloy M152:
-
High-Temperature Performance: Alloy M152 is designed for use at elevated temperatures and offers excellent creep resistance and strength retention at high temperatures.
-
Corrosion Resistance: The alloy provides good corrosion resistance in various aggressive environments, including those containing sulfuric acid, hydrochloric acid, and other acids.
-
Oxidation Resistance: Alloy M152 exhibits good oxidation resistance at high temperatures, which is crucial for applications involving extreme heat.
-
Applications: Alloy M152 is commonly used in industries such as chemical processing, petrochemical, and power generation, where high-temperature strength and corrosion resistance are required.
-
Weldability: Alloy M152 can be welded using common welding methods, but care should be taken to maintain its properties and avoid reducing its corrosion resistance.
-
Forms: Alloy M152 is available in various forms, including sheets, plates, bars, and tubes.
Due to its combination of high-temperature strength, corrosion resistance, and oxidation resistance, Alloy M152 is chosen for critical applications where extreme conditions are present. If you're considering using Alloy M152 for a specific project, consulting with materials experts or manufacturers is recommended to ensure it meets your desired performance requirements, especially in terms of high-temperature and corrosion resistance capabilities.
Reference Material (RM): A reference material, or RM, is a material with a known composition or property that is used for informational purposes to look at analytical instruments, methods, or procedures. It serves as a point of comparison to ensure the accuracy and reliability of measurements. Reference materials can vary in terms of their level of characterization and traceability. Some reference materials may have well-defined properties, but they might not have undergone the rigorous testing and certification process that certified reference materials (CRMs) undergo. Reference Material chemical compositions are for information purposes.
Certified Reference Material (CRM): A certified reference material, or CRM, is a type of reference material that has been thoroughly analyzed and characterized using multiple validated methods to determine its composition or properties. The results of these analyses are then used to establish certified values, along with associated uncertainties. CRMs are produced and certified by accredited organizations or laboratories following internationally recognized standards, such as ISO Guide 34 and ISO/IEC 17025. The certification process includes interlaboratory comparison and statistical analysis to ensure accuracy and traceability.
In summary, the main difference between a reference material and a certified reference material lies in the level of characterization, validation, and certification. CRMs have undergone a more comprehensive and rigorous testing process, resulting in certified values and uncertainties that can be confidently used for instrument calibration, quality control, and research. Reference materials, on the other hand, can provide a point of comparison but might not have the same level of certification and traceability as CRMs. When accuracy and traceability are critical, certified reference materials are preferred.
