Differences between SUS 304 and SUS 304L:

• 304L has a 0.03max carbon and is good for welding whereas 304 has a mid range level of carbon
• 304L and 304 are austenitic alloys, which mean that a nonmagnetic solid solution of ferric carbide or carbon in iron is used in giving this stainless steel its corrosion-resistance properties.)

Applications:

• Stainless Steel has a beautiful surface appearance and strong resistance to corrosion and heat. It is very workable and shows excellent performance even at low temperatures.
• A highly popular material known for its strength and ornamental values, it is widely used to achieve architectural aesthetics.
• Excellent in a wide range of atmospheric environments and many corrosive media
• Subject to pitting and crevice corrosion in warm chloride environments, and to stress corrosion cracking above 60oC
• Good oxidation resistance
• Grade 304L stainless steel is more resistant to carbide precipitation
• Applied in food processing equipment, particularly in beer brewing, milk processing and wine making
• Kitchen benches, sinks, troughs, equipment and appliances
• Architectural panelling, railings and trim
• Chemical containers, including for transport
• Heat exchangers
• Woven or welded screens for mining, quarrying and water filtration
• Threaded fasteners
• Springs
