아이시 304 2b 스테인레스 스틸
The difference between AISI and ASTM lies in their roles:
-
아이시 defines what the steel is (composition and grade)
-
ASTM defines how the steel performs, is produced, and is tested
을 위한 아이시 304 2B 스테인레스 스틸, both standards are essential to ensure 일관된 품질, 성능, and application suitability in global markets.

- 설명
아이시 304 2B 스테인레스 스틸 is one of the most widely used stainless steel sheet materials. To understand its designation, it is important to clarify the difference between 아이시 그리고 ASTM, as they represent different types of standards in the stainless steel industry.
What Is AISI?
아이시 (미국 철강 연구소) is a classification system mainly used to:
-
Define steel grades based on chemical composition
-
Provide a numbering system (~와 같은 304, 316, 430)
-
집중하다 material type and alloy content, not detailed specifications
예: 아이시 304
-
크롬 (Cr): 18-20%
-
니켈 (~ 안에): 8-10.5%
-
Austenitic stainless steel with good corrosion resistance
What Is ASTM?
ASTM (미국 재료 시험 협회) 제공하다 comprehensive technical standards, 포함:
-
기계적 성질 (힘, 연장)
-
Manufacturing processes
-
Testing methods
-
Tolerances and delivery conditions
ASTM standards define how the material should perform and be supplied.
Key Differences Between AISI and ASTM
| 측면 | 아이시 | ASTM |
|---|---|---|
| 유형 | Classification system | Technical standard |
| Focus | 화학 성분 | 성능 + 테스트 + production |
| 목적 | Identify steel grade | Define product requirements |
| 예 | 아이시 304 | ASTM A240 Type 304 |
| 범위 | General | Detailed and enforceable |
How They Work Together
In practice, AISI and ASTM are used together:
-
아이시 304 → identifies the material composition
-
ASTM A240 304 → specifies sheet/plate requirements such as:
-
두께 공차
-
기계적 성질
-
표면 마무리 (예를 들어, 2B 마무리)
-
What Does “2B Finish” Mean?
을 위한 아이시 304 2B 스테인레스 스틸 시트:
-
콜드 롤, 열처리된, 절인, and skin-passed
-
매끄러운, 무광택 표면
-
적합합니다 industrial and general-purpose applications
Practical Example
A full material description might be:
-
아이시 304 / ASTM A240 Type 304, 2B 마무리
This means:
-
Grade defined by AISI (구성)
-
Manufactured and tested according to ASTM standards
-
Surface finish specified as 2B
