Steel Grade Comparison for Different Countries
If you are not able to find the grade of steel you are looking for, please contact us . We would love to help you find what you are looking for.
What should I do if I cannot find the steel grade I am looking for?
If you cannot locate a specific steel grade in our table, please contact us. Our team can help identify equivalent grades and provide guidance for your application.
Which standards are included in your steel grade comparison?
Our comparison covers multiple international standards, including:
• China (GB)
• Japan (JIS)
• USA (ASTM & UNS)
• Europe (EN)
• Russia (GOST)
• Germany (DIN)
• India (IS)
• Australia (AS)
• China (GB)
• Japan (JIS)
• USA (ASTM & UNS)
• Europe (EN)
• Russia (GOST)
• Germany (DIN)
• India (IS)
• Australia (AS)
What types of stainless steel are included in the table?
We include the main stainless steel classifications:
- Austenitic Stainless Steel
- Ferritic Stainless Steel
- Martensitic Stainless Steel
- Duplex Stainless Steel
Are the grades listed interchangeable across countries?
Grades are often comparable but may have minor differences in chemical composition or mechanical properties. Always verify the application requirements before substituting between standards.
Can you provide help for non-stainless steel grades as well?
Yes. While this table focuses on stainless steel, our team can assist with other steel grades and provide equivalent standards if needed.
How are the grades identified across different countries?
Grades are matched based on metallographic structure, chemical composition, and mechanical properties. For example, SUS304 (JIS) is equivalent to 06Cr19Ni10 (GB), A240 TP304 (ASTM), and 1.4301 (EN).
Do you provide guidance on selecting the right grade for specific applications?
Yes. Once you provide your application requirements (corrosion resistance, temperature, mechanical load, etc.), we can recommend suitable grades and international equivalents.
Can you supply custom steel grades if a standard grade is not available?
Yes. Our production and supply chain can support custom or special grades based on your project requirements.
