Austenitic stainless steels are known for their excellent corrosion resistance, high strength, and good formability. The grades SUS303TKA, SUS304TKA, SUS304LTKA, SUS316TKA, and SUS316LTKA are specifically designed for various machine and structural applications. These materials are commonly used in industries such as food processing, chemical processing, and construction due to their durability and resistance to harsh environments.
The specifications for these stainless steel tubes are outlined in the JIS G3446 standard, which provides guidelines for the manufacturing and testing of stainless steel tubes used in various applications. The tubes are available in different sizes and thicknesses to meet specific requirements.
The following table presents the chemical composition of the specified stainless steel grades:
| Grade | C (%) | Si (%) | Mn (%) | P (%) | S (%) | Cr (%) | Ni (%) | Mo (%) |
|---|---|---|---|---|---|---|---|---|
| SUS303TKA | 0.15 | 1.00 | 2.00 | 0.045 | 0.030 | 17.00 | 8.00 | - |
| SUS304TKA | 0.08 | 1.00 | 2.00 | 0.045 | 0.030 | 18.00 | 8.00 | - |
| SUS304LTKA | 0.03 | 1.00 | 2.00 | 0.045 | 0.030 | 18.00 | 8.00 | - |
