Steel Grade
The steel grades specified in JIS G3468 are designed to meet the requirements for various applications, particularly in low-temperature environments. Each grade offers distinct advantages based on its chemical composition and mechanical properties.
Application
These stainless steel tubes are widely used in industries such as:
- Cryogenic applications
- Oil and gas pipelines
- Chemical processing
- Power generation
- Food and beverage processing
Possible Alternative Grades
While the specified grades are optimal for low-temperature applications, alternative grades may include:
- SUS316: Offers better corrosion resistance.
- SUS321: Provides improved high-temperature stability.
- SUS310S: A lower carbon version of SUS310, suitable for high-temperature applications.
