JIS G4304 SUS304 stainless steel equivalent

JIS G4304 SUS304 stainless steel equivalent

JIS G4304 SUS304 stainless steel is a widely used austenitic stainless steel grade under the Japanese standard JIS G4304, commonly used for hot-rolled stainless steel plates, sheets, and strips. Its equivalent grades in other international standards are as follows:

1. ASTM/ASME (USA):  
SUS304 is equivalent to ASTM A240/A276 Type 304. These standards define 304 stainless steel for applications like pressure vessels, construction, and general industrial uses.

2. EN Standard (Europe):  
The closest equivalent is 1.4301 (X5CrNi18-10) under the EN 10088-1 and EN 10028-7 standards. It is widely used in architectural, food processing, and chemical industries.

3. ISO Standard:  
Equivalent to ISO 15510 18-9-3 or similar grades, which are part of the global stainless steel classification system.

4. GB Standard (China):  
The equivalent is GB/T 1220 06Cr19Ni10, commonly used in Chinese industries for general corrosion resistance and durability.

5. IS Standard (India):  
SUS304 corresponds to IS 6911 Grade 304, widely used in food-grade applications and manufacturing.

6. UNI Standard (Italy):  
Equivalent to X5CrNi1810 (UNI 6900/6901) for general stainless steel applications.

Applications of SUS304 Stainless Steel:
SUS304 (and its equivalents) is used in diverse applications due to its excellent corrosion resistance, good mechanical properties, and weldability. Typical uses include kitchen equipment, chemical tanks, medical devices, and structural components.
