1. **What is SA 105 pipe material?**
SA 105 is an ASTM specification for carbon steel forgings intended for high-temperature service, primarily used for flanges, fittings, and other pressure-containing parts in piping systems. It is a low-carbon steel with good strength and impact resistance.
2. **What is SA 213 GR T11 equivalent to?**
SA 213 Grade T11 is a chromium-molybdenum alloy steel tube material used in boilers and superheaters. Its closest equivalents are:
- **DIN Standard:** 15Mo3 (1.5415)
- **EN Standard:** 16Mo3
- **ISO Standard:** 2218 (T11)
3. **What is SA 106 pipe material?**
SA 106 is an ASTM specification for seamless carbon steel pipe designed for high-temperature service, commonly used in power plants, refineries, and process piping. It comes in three grades (A, B, C) with increasing tensile strength.
4. **What is a SA 210 tube made of?**
SA 210 is an ASTM specification for seamless medium-carbon steel tubes used in boilers and superheaters. The most common grade, **SA 210 Grade C**, is made of carbon-manganese steel with higher strength than Grades A and B.
5. **What are ASTM pipe grades?**
ASTM pipe grades are standardized classifications for pipes based on material composition, mechanical properties, and intended use. Common ASTM pipe grades include:
- **Carbon Steel:** A53, A106, A333
- **Alloy Steel:** A335 (P11, P22, P91), A213 (T11, T22, T91)
- **Stainless Steel:** A312 (TP304, TP316)
- **Low-Temp Steel:** A333 (Grade 6 for -45°C service)
- **High-Yield Steel:** A671, A672 for welded pipes
Each grade specifies chemical composition, tensile strength, and application limits (e.g., temperature, pressure).
