JIS G3466 STKR400 is a standard specification for carbon steel square and rectangular tubes used in general structural applications. These tubes are known for their excellent mechanical properties and versatility, making them suitable for various construction and engineering projects.
The material used in the production of STKR400 tubes is carbon steel, which provides a good balance of strength, ductility, and weldability. This makes it an ideal choice for structural applications where durability and performance are critical.
The specification outlines the requirements for the manufacturing and testing of the steel tubes, ensuring they meet the necessary standards for structural integrity and performance.
| Element | Composition (%) |
|---|---|
| Carbon (C) | 0.20 - 0.25 |
| Manganese (Mn) | 0.30 - 0.60 |
| Phosphorus (P) | ≤ 0.035 |
| Sulfur (S) | ≤ 0.025 |
| Silicon (Si) | ≤ 0.40 |
| Iron (Fe) | Balance |
| Property | Value |
|---|---|
| Yield Strength (MPa) | ≥ 245 |
| Tensile Strength (MPa) | 400 - 510 |
| Elongation (%) | ≥ 20 |
| Hardness (HB) | ≤ 150 |
The STKR400 grade is specifically designed for structural applications, providing a reliable option for engineers and architects in their designs.
STKR400 tubes are widely used in various applications, including:
While STKR400 is a popular choice, 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.
