JIS G3462 is a Japanese industrial standard that specifies alloy steel tubes used for boilers and heat exchangers. These tubes are designed to withstand high temperatures and pressures, making them ideal for use in power plants, chemical plants, and other industrial applications. The grades STBA12, STBA13, STBA20, STBA22, and STBA23 are among the most commonly used in this standard.
The chemical composition of these alloy steel grades is crucial for their performance. Below is a table detailing the typical chemical composition for each grade:
| Element | STBA12 | STBA13 | STBA20 | STBA22 | STBA23 |
|---|---|---|---|---|---|
| Carbon (C) | 0.15 max | 0.15 max | 0.15 max | 0.15 max | 0.15 max |
| Silicon (Si) | 0.50 max | 0.50 max | 0.50 max | 0.50 max | 0.50 max |
| Manganese (Mn) | 0.30-0.60 | 0.30-0.60 | 0.30-0.60 | 0.30-0.60 | 0.30-0.60 |
| Phosphorus (P) | 0.035 max | 0.035 max | 0.035 max | 0.035 max | 0.035 max |
| Sulfur (S) | 0.035 max | 0.035 max | 0.035 max | 0.035 max | 0.035 max |
| Chromium (Cr) | 0.50-1.00 | 0.50-1.00 | 0.50-1.00 | 0.50-1.00 | 0.50-1.00 |
| Molybdenum (Mo) | 0.45-0.65 | 0.45-0.65 | 0.45-0.65 | 0.45-0.65 | 0.45-0.65 |
The mechanical properties of these tubes are critical for their performance in high-pressure and high-temperature environments. The table below outlines the typical mechanical properties:
| Property | STBA12 | STBA13 | STBA20 | STBA22 | STBA23 |
|---|---|---|---|---|---|
| Tensile Strength (MPa) | ≥ 415 | ≥ 415 | ≥ 415 | ≥ 415 | ≥ 415 |
| Yield Strength (MPa) | ≥ 205 | ≥ 205 | ≥ 205 | ≥ 205 | ≥ 205 |
| Elongation (%) | ≥ 30 | ≥ 30 | ≥ 30 | ≥ 30 | ≥ 30 |
The steel grades STBA12, STBA13, STBA20, STBA22, and STBA23 are part of the JIS G3462 standard, each offering specific properties tailored for different applications. These grades are selected based on the specific requirements of the application, such as temperature, pressure, and environmental conditions.
These alloy steel tubes are primarily used in:
While JIS G3462 grades are widely used, there are alternative grades that may be considered based on specific requirements:
A: manufacturer,also can do trading.
A: Generally speaking,it is 10-15 days if the goods are in stock,or it is 30-40 days if the goods are not in stock, it is according to quantity.
A: Yes, we could offer the sample for free charge but need pay the cost of freight.
A: Payment<=2000USD, 100% in advance. Payment>=2000USD, 30% T/T in advance ,balance before shippment.
