The JIS G3443-1 standard specifies the requirements for seamless steel tubes used in water service applications. The primary materials used in the production of these tubes are carbon steel grades, which are designed to provide excellent corrosion resistance and mechanical properties.
The seamless steel tubes covered under JIS G3443-1 are categorized into different grades based on their mechanical properties and chemical composition. The standard outlines the dimensions, tolerances, and testing methods to ensure the quality and performance of the tubes.
Grade | Carbon (C) | Manganese (Mn) | Phosphorus (P) | Sulfur (S) | Silicon (Si) |
---|---|---|---|---|---|
STW290 | 0.18 max | 0.60 - 0.90 | 0.030 max | 0.030 max | 0.10 - 0.40 |
STW370 | 0.20 max | 0.60 - 0.90 | 0.030 max | 0.030 max | 0.10 - 0.40 |
STW400 | 0.25 max | 0.60 - 0.90 | 0.030 max | 0.030 max | 0.10 - 0.40 |
Grade | Yield Strength (MPa) | Tensile Strength (MPa) | Elongation (%) |
---|---|---|---|
STW290 | 290 | 410 - 540 | 20 |
STW370 | 370 | 490 - 620 | 20 |
STW400 | 400 | 510 - 640 | 20 |
The steel grades specified in JIS G3443-1 include STW290, STW370, and STW400. Each grade is designed to meet specific mechanical and chemical property requirements, making them suitable for various applications in water service.
