10CrMo910 seamless alloy pipe is used for the heating surface tubes in low- and medium-pressure boilers (with an operating pressure generally not exceeding 5.88 MPa and an operating temperature below 450°C). It is also utilized for the heating surface tubes, economizers, superheaters, reheaters, and pipes for petrochemical industry applications in high-pressure boilers (with an operating pressure generally above 9.8 MPa and an operating temperature ranging from 450°C to 650°C).
A213 T22 V.S. DIN 17175 10CrMo910
| Comparison Item | A213 T22 | DIN 17175 10CrMo910 |
|---|---|---|
| Standard System | ASME (American Society of Mechanical Engineers) | DIN (Deutsches Institut für Normung, German Industrial Standard) |
| Material Grade | T22 (a grade in the A213 standard for seamless ferritic and austenitic alloy steel boiler, superheater, and heat exchanger tubes) | 10CrMo910 (a heat-resistant alloy steel grade specified in DIN 17175) |
| Chemical Composition | Similar to 10CrMo910, but with slight differences in trace elements and allowable impurities. | Composed of elements such as carbon (C), chromium (Cr), molybdenum (Mo), etc., with specific proportions defined in DIN 17175. |
| Mechanical Properties | High-temperature tensile strength and creep resistance are key requirements, with specific values defined in the A213 standard. | Also requires good high-temperature mechanical properties, including tensile strength, yield strength, and elongation, as per DIN 17175. |
| Heat Treatment | Typically supplied in the normalized and tempered condition. | Usually supplied in the normalized condition. |
| Applications | Used for boiler tubes, superheaters, reheaters, and heat exchangers in power plants and industrial facilities. | Primarily used for high-pressure boiler tubes operating at high temperatures, such as in power generation and industrial boiler systems. |
| Inspection & Testing | Subject to strict non-destructive testing (NDT), hydrostatic testing, and other quality control measures as per ASME requirements. | Also requires NDT, hydrostatic testing, and other inspections to ensure quality and compliance with DIN standards. |
| Global Acceptance | Widely accepted and used in the Americas, Asia, and other regions following ASME standards. | Mainly used in Europe and regions influenced by German standards, but also recognized globally. |
