JIS G3461 is a Japanese industrial standard that specifies the requirements for carbon steel tubes used in boilers and heat exchangers. These tubes are designed to withstand high temperatures and pressures, making them ideal for use in industrial applications. The standard covers three main grades: STB340, STB410, and STB510, each offering different mechanical properties to suit various operational needs.
The chemical composition of JIS G3461 carbon steel tubes is crucial for determining their suitability for specific applications. Below is a table presenting the typical chemical composition for each grade:
| Element | STB340 (%) | STB410 (%) | STB510 (%) |
|---|---|---|---|
| Carbon (C) | ≤ 0.18 | ≤ 0.20 | ≤ 0.23 |
| Silicon (Si) | ≤ 0.35 | ≤ 0.35 | ≤ 0.35 |
| Manganese (Mn) | ≤ 0.55 | ≤ 0.60 | ≤ 0.60 |
| Phosphorus (P) | ≤ 0.030 | ≤ 0.030 | ≤ 0.030 |
| Sulfur (S) | ≤ 0.030 | ≤ 0.030 | ≤ 0.030 |
The mechanical properties of these tubes are essential for ensuring they can withstand the operational stresses they will encounter. The table below outlines the mechanical properties for each grade:
| Property | STB340 | STB410 | STB510 |
|---|---|---|---|
| Tensile Strength (MPa) | ≥ 340 | ≥ 410 | ≥ 510 |
| Yield Strength (MPa) | ≥ 175 | ≥ 225 | ≥ 295 |
| Elongation (%) | ≥ 35 | ≥ 30 | ≥ 25 |
The JIS G3461 standard includes three primary grades:
JIS G3461 carbon steel tubes are widely used in:
While JIS G3461 is a popular choice, there are alternative grades that may be considered depending 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.
