Лист нержавеющей стали ASTM
АСТМ, АИСИ, ОН, and SUS are different stainless steel classification systems used in different regions and industries:
- АСТМ focuses on engineering standards and performance testing
- АИСИ provides simple grade naming (304, 316, и т. д.)
- ОН is the Japanese industrial standard system
- ИХ is the stainless steel designation under JIS
- Описание
ASTM stainless steel sheet refers to stainless steel materials produced and tested under the ASTM (Американское общество испытаний и материалов) standard system. In global trade and engineering, stainless steel sheets are commonly identified using different standards such as АСТМ, АИСИ, ОН, and SUS, which describe similar materials but follow different classification systems.
Understanding these standards is important for material selection, international procurement, and technical communication.
1. ASTM Стандарт (USA)
АСТМ is one of the most widely used international material standards, especially in engineering and export markets.
Features of ASTM Standard
- Defines химический состав, механические свойства, и методы тестирования
- Широко используется в строительстве, нефтехимический, и промышленное применение
- Often paired with ASME specifications in pressure equipment
Common ASTM Stainless Steel Grades
| ASTM Grade | Equivalent Type |
|---|---|
| АСТМ 304 | General austenitic stainless steel |
| АСТМ 316 | Marine-grade stainless steel |
| АСТМ 430 | Ферритная нержавеющая сталь |
| АСТМ 201 | Low-nickel stainless steel |
ASTM focuses more on performance requirements and testing methods.
2. AISI Standard (USA Steel Institute System)
АИСИ (Американский институт железа и стали) is an older naming system that mainly defines stainless steel by grade numbers.
Features of AISI System
- Simple grade identification system (например, 304, 316, 430)
- Does not always specify detailed testing requirements
- Often aligned with ASTM materials
Common AISI Grades
| AISI Grade | Описание |
|---|---|
| АИСИ 304 | Standard corrosion-resistant stainless steel |
| АИСИ 316 | Molybdenum-enhanced corrosion resistance |
| АИСИ 430 | Ферритная нержавеющая сталь |
| АИСИ 201 | Cost-effective alternative |
👉 AISI is mainly a naming system, not a full technical standard.
3. JIS Standard (Japan Industrial Standard)
ОН (Japanese Industrial Standards) is widely used in Japan and Asia for stainless steel classification.
Features of JIS System
- Uses different codes compared to ASTM/AISI
- Includes detailed material specifications and processing requirements
- Common in machinery, автомобильный, and precision industries
Common JIS Stainless Steel Grades
| JIS Grade | Эквивалент |
|---|---|
| СУС304 | Equivalent to 304 |
| СУС316 | Equivalent to 316 |
| СУС430 | Equivalent to 430 |
| SUS201 | Equivalent to 201 |
4. SUS Standard (Japan Stainless Steel Designation)
ИХ is part of the JIS system and specifically refers to stainless steel grades.
Features of SUS System
- “SUS” stands for Steel Use Stainless
- Directly used in material naming (например, СУС304)
- Very common in Asian markets and manufacturing drawings
Common SUS Grades
| SUS Grade | Характеристики |
|---|---|
| СУС304 | General-purpose stainless steel |
| СУС316 | Высокая коррозионная стойкость |
| СУС430 | Ферритная нержавеющая сталь |
| СУС301 | High-strength stainless steel |
5. Comparison of ASTM, АИСИ, ОН, ИХ
| System | Region | Тип | Main Feature |
|---|---|---|---|
| АСТМ | USA / Global | Engineering standard | Detailed performance & тестирование |
| АИСИ | USA | Naming system | Simple grade identification |
| ОН | Япония | National standard | Full technical specification |
| ИХ | Япония | Material code | Stainless steel designation |
6. Equivalent Relationship Example (304 Нержавеющая сталь)
| Стандартный | Имя |
|---|---|
| АСТМ | АСТМ 304 |
| АИСИ | 304 |
| ОН | СУС304 |
| В (EU reference) | 1.4301 |
All refer to similar stainless steel chemistry but follow different standard systems.
7. Key Differences in Practice
ASTM vs AISI
- ASTM = technical standard (характеристики + тестирование)
- AISI = grade naming system
JIS vs SUS
- JIS = full industrial standard system
- SUS = stainless steel grade code within JIS
Global Usage Trend
- ASTM dominates international engineering projects
- SUS/JIS widely used in Asia
- AISI still used in trade naming conventions
