Line up（3）
| Model number | overview |
|---|---|
| SUS304L (low carbon type) | This is a low carbon steel type with reduced carbon content compared to SUS304, which minimizes the risk of intergranular corrosion during welding. Its corrosion resistance and workability are almost equivalent to SUS304, making it suitable for structures and piping applications where post-weld heat treatment is difficult. In facilities with many welded structures, SUS304L is often selected over SUS304. |
| SUS304H (high carbon type) | This is a steel grade with a higher carbon content than SUS304, designed to maintain strength in high-temperature environments. Its corrosion resistance is comparable to that of SUS304, but it excels in creep strength and high-temperature endurance, making it suitable for boiler components and high-temperature piping. SUS304 is commonly used for room temperature applications, while SUS304H is selected when high-temperature strength is required. |
| SUS304N1/304N2 (Nitrogen-added type) | This is a SUS304 series steel type that has enhanced strength by adding nitrogen (N). It maintains corrosion resistance equivalent to SUS304 while improving yield strength and tensile strength, making it suitable for structural applications where reduced thickness and lightweight are required. N2 is even higher in strength than N1 and has a proven track record in the field of construction structural materials. |
