What is the difference between P235TR1 and P235TR2 pipe
1. Chemical composition and standard requirements
Aluminum content: P235TR1 has no mandatory requirements for aluminum (Al) content, while P235TR2 may need to meet more stringent trace element control.
Standard classification: Both comply with European standard EN 10216-1, but TR1 and TR2 represent different quality levels, and TR2 has stricter process control.
2. Mechanical property differences
Impact energy requirements: P235TR1's impact energy (low temperature or room temperature) is not mandatory, while P235TR2 usually needs to meet specific impact toughness indicators, such as additional tests when used in low temperature environments.
3. Application scenarios
Versatility: P235TR1 is mostly used for general pipelines, container manufacturing and conventional structural parts, where performance requirements are not high.
High performance requirements: P235TR2 is more suitable for scenarios that require material toughness or low temperature resistance, such as high-pressure pipelines or special equipment.
4. Production and procurement
Inventory and specifications: The inventory of P235TR2 in the market is usually larger (such as 3320 tons), while the inventory of P235TR1 is relatively small (such as 3025 tons), reflecting the difference in their application needs.
Summary
The core difference between P235TR1 and P235TR2 lies in the chemical composition control standard and impact toughness requirements. TR2 is suitable for more demanding engineering scenarios through stricter element control and performance testing, while TR1 meets conventional needs with basic performance.
