10CrMo910 V.S. P22
| Property/Characteristic | 10CrMo910 (DIN 17175) | P22 (ASTM A335 / ASME SA335) |
|---|---|---|
| Standard | DIN 17175 (German standard for seamless steel pipes) | ASTM A335 / ASME SA335 (American standard for seamless ferritic alloy-steel pipes) |
| Chemical Composition | Contains chromium (Cr), molybdenum (Mo), and carbon (C) as key alloying elements, with specific limits on other elements. | Similar to 10CrMo910, but with slight variations in elemental composition and limits (e.g., chromium, molybdenum, carbon, etc.). |
| Mechanical Properties | Designed for high-temperature applications, with good tensile strength, creep resistance, and oxidation resistance at elevated temperatures. | Also designed for high-temperature service, offering excellent tensile strength, creep strength, and relaxation resistance. |
| Heat Treatment | Typically supplied in the normalized condition or normalized and tempered, depending on the thickness and application requirements. | Usually supplied in the normalized and tempered condition to achieve the desired mechanical properties. |
| Applications | Primarily used in high-pressure and high-temperature boiler systems, superheaters, heat exchangers, and other power plant components. | Widely used in power generation, petrochemical plants, and refineries for high-pressure and high-temperature piping systems, boilers, and heat exchangers. |
| Global Usage | Commonly used in Europe and other regions following DIN standards. | Widely accepted and used globally, especially in countries following ASTM/ASME standards. |
| Key Differences | - Follows DIN 17175 standard. - Specific chemical composition ranges. - May have slight variations in heat treatment and resulting properties compared to P22. |
- Follows ASTM A335 / ASME SA335 standard. - Different (but similar) chemical composition limits. - Typically supplied in normalized and tempered condition. |
