Low temperature carbon steel A516 Gr 55 plates A516Gr55 HIC steel plate

A516 Gr55 is a low-temperature carbon steel plate commonly used in the manufacture of low-temperature pressure vessels and storage tanks, while A516 Gr55 HIC steel plate undergoes hydrogen induced cracking (HIC) testing to ensure its good crack resistance in hydrogen containing environments.

1. Application field: A516 Gr 55 steel plate is usually suitable for pressure vessel manufacturing under low temperature conditions, such as liquefied natural gas (LNG) storage tanks. A516 Gr55 HIC steel plate is particularly suitable for applications that require high sensitivity to hydrogen induced cracking.

2. Mechanical properties: A516 Gr 55 steel plates have good strength and toughness in low temperature environments, ensuring stable operation of equipment under extreme conditions.

3. HIC testing: A516 Gr55 HIC steel plate undergoes hydrogen induced cracking testing to evaluate its performance in hydrogen embrittlement environments, in order to avoid possible cracking problems and improve equipment reliability.

4. Chemical composition: Typical chemical compositions include low carbon content, sulfur content controlled at extremely low levels, and the addition of other alloying elements to meet performance requirements at low temperatures.

5. Standard compliance: Complies with ASTM A516 standard to ensure material quality and performance meet relevant regulatory requirements.

6. Selection suggestion: When selecting A516 Gr 55 materials, HIC test results should be considered based on specific engineering requirements to ensure that the selected materials meet project requirements and have the required reliability and safety.
