자주 묻는 질문 (FAQ)

What is the primary benefit of using AISI 321 stainless steel over AISI 304?
- AISI 321 offers superior resistance to intergranular corrosion, especially in high-temperature environments, and has better weldability due to the addition of titanium. It is the ideal choice for applications that require enhanced heat resistance.
Can AISI 321 stainless steel withstand high temperatures?
- 예, AISI 321 is well-suited for high-temperature applications. It can withstand temperatures up to 900°C (1652° F) in continuous service and up to 925°C (1697° F) for intermittent service.
Is AISI 321 stainless steel magnetic?
- AISI 321 is non-magnetic in the annealed condition. However, it may become slightly magnetic when cold-worked or after significant deformation.
Can AISI 321 stainless steel be welded?
- 예, AISI 321 is highly weldable. The titanium content prevents carbide precipitation during welding, ensuring strong, durable welds without the risk of sensitization.
What is the tensile strength of AISI 321 스테인레스 스틸?
- The tensile strength of AISI 321 stainless steel is typically between 520 MPa and 720 MPa, making it suitable for high-strength applications in harsh environments.
What are the common surface finishes for AISI 321 스테인레스 스틸?
- AISI 321 stainless steel coils are available in several surface finishes, including 2B (matte finish), 바 (bright annealed), No.4 (brushed finish), and No.8 (mirror finish), depending on the specific requirements of the application.
