JIS G3462 is a Japanese Industrial Standard (JIS) that specifies the requirements for seamless carbon alloy steel tubes designed for use in boilers and heat exchangers. These tubes are characterized by their impressive durability, excellent heat transfer properties, and resistance to high temperatures and pressure. The standard outlines the material, specification, key features, chemical composition, and mechanical properties for the tubes.
JIS G3462 seamless steel tubes are manufactured using carbon alloy steel. The tubes are designed to withstand high temperatures and pressure, making them suitable for various industrial applications. The specification covers dimensions, tolerances, appearance, and weight of the tubes to ensure their conformity and quality.
JIS G3462 seamless steel tubes offer several key features that make them ideal for boiler and heat exchanger applications. These features include:
The following table presents the chemical composition of JIS G3462 seamless steel tubes:
| Element | Chemical Composition (% by weight) |
|---|---|
| Carbon (C) | 0.08 - 0.18 |
| Silicon (Si) | 0.10 - 0.35 |
| Manganese (Mn) | 0.30 - 0.60 |
| Phosphorus (P) | 0.035 (max) |
| Sulfur (S) | 0.035 (max) |
| Chromium (Cr) | 0.90 - 1.20 |
| Molybdenum (Mo) | 0.15 - 0.25 |
The mechanical properties of JIS G3462 seamless steel tubes are as follows:
| Property | Value |
|---|---|
| Tensile Strength | 380 - 550 MPa |
| Yield Strength | 180 - 350 MPa |
| Elongation | 25% (min) |
| Hardness | HRB 85 (max) / HV 170 (max) |
| Impact Test | No cracks or breaks |
The steel grade specified by JIS G3462 includes STBA12, STBA13, STBA20, STBA22, STBA23, STBA24, STBA25, and STBA26. Each grade has unique chemical and mechanical properties suitable for specific applications.
JIS G3462 seamless steel tubes find wide application in various industries, primarily in boilers and heat exchangers. These tubes are used for conveying high-temperature fluids, such as steam or oil, within these systems. Additionally, they are employed in power plants, chemical plants, refineries, and other settings where reliable heat transfer and pressure resistance are essential.
Although JIS G3462 specifies carbon alloy steel tubes, alternatives with similar properties can be considered based on specific requirements. Other notable standards that offer seamless tubes suitable for boiler and heat exchanger applications include ASTM A192, ASTM A210, and DIN 17175. It is important to consult the appropriate standards and consider the specific needs of the application before selecting an alternative grade.
