Key Features
- SUS304 is shared KS/JIS, equivalent to DIN X5CrNi18-10 and ANSI 304; represents 80% of all stainless steel usage
- SUS316 adds 2–3% Mo for enhanced chloride/seawater resistance; suitable for chemical and marine environments
- L grades (304L/316L) are low-carbon to prevent sensitization (intergranular corrosion) after welding
Key Applications
Food machinery, medical equipment, chemical piping, marine installations, architectural cladding
