Stainless Steel ASTM A312 TP321 ， A213 TP321， A269 TP321， Pickled and Annealed ， Plain End，3" SCH40
1.4541 is the European norm (EN) designation for a stainless steel grade often referred to as TP321 in various ASTM standards. Let's break down the specifications and standards associated with this heat exchanger tube:
ASTM A312: This is an ASTM specification that covers seamless， welded， and heavily cold worked austenitic stainless steel pipes for general corrosive service and high-temperature applications. The A312 standard ensures the manufacturing and material requirements for the tubes used in various industries， including heat exchangers.
ASTM A213: Another ASTM specification， A213， covers seamless ferritic and austenitic alloy-steel boiler， superheater， and heat exchanger tubes. The A213 standard provides guidelines for seamless tubes used in high-temperature and corrosive environments.
ASTM A269: The ASTM A269 specification focuses on seamless and welded austenitic stainless steel tubing for general service. It is commonly used in applications requiring corrosion resistance and high-temperature strength. A269 ensures the mechanical and material properties of the tubes.
TP321: TP321 is the ASTM designation for stainless steel grade 1.4541. It represents a titanium-stabilized austenitic stainless steel with good corrosion resistance and high-temperature strength. TP321 is specifically designed to resist intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 800-1500°F (427-816°C).
The 1.4541 (TP321) heat exchanger tube offers several advantages:
1️⃣ Corrosion Resistance: It provides excellent resistance to corrosion in various environments， including acidic and chloride-containing media.
2️⃣ High-Temperature Strength: TP321 exhibits good mechanical properties at elevated temperatures， making it suitable for high-temperature applications such as heat exchangers.
3️⃣ Intergranular Corrosion Resistance: The titanium stabilization in TP321 helps prevent intergranular corrosion， ensuring the long-term integrity of the tube when exposed to high temperatures.
4️⃣ Weldability: TP321 offers good weldability， allowing for ease of fabrication and joining processes.
