EN10217-1 is a European standard that specifies the requirements for welded steel tubes intended for pressure purposes. These tubes are designed to operate at room temperature and are commonly used in various industrial applications. The standard covers several steel grades, including P195TR1, P195TR2, P235TR1, P235TR2, and P265TR1, each with specific properties to meet different requirements.
The chemical composition of these steel grades is crucial for their performance. Below is a table presenting the typical chemical composition for each grade:
| Element | P195TR1 | P195TR2 | P235TR1 | P235TR2 | P265TR1 |
|---|---|---|---|---|---|
| Carbon (C) | ≤ 0.20% | ≤ 0.20% | ≤ 0.16% | ≤ 0.16% | ≤ 0.20% |
| Manganese (Mn) | ≤ 1.40% | ≤ 1.40% | ≤ 1.20% | ≤ 1.20% | ≤ 1.40% |
| Phosphorus (P) | ≤ 0.025% | ≤ 0.025% | ≤ 0.025% | ≤ 0.025% | ≤ 0.025% |
| Sulfur (S) | ≤ 0.020% | ≤ 0.020% | ≤ 0.020% | ≤ 0.020% | ≤ 0.020% |
| Silicon (Si) | ≤ 0.40% | ≤ 0.40% | ≤ 0.35% | ≤ 0.35% | ≤ 0.40% |
The mechanical properties of these steel grades are essential for determining their suitability for specific applications. The table below outlines the typical mechanical properties:
| Property | P195TR1 | P195TR2 | P235TR1 | P235TR2 | P265TR1 |
|---|---|---|---|---|---|
| Yield Strength (MPa) | ≥ 195 | ≥ 195 | ≥ 235 | ≥ 235 | ≥ 265 |
| Tensile Strength (MPa) | 320-440 | 320-440 | 360-500 | 360-500 | 410-570 |
| Elongation (%) | ≥ 24 | ≥ 24 | ≥ 25 | ≥ 25 | ≥ 22 |
The steel grades covered under EN10217-1 are specifically designed to meet the demands of various applications. Each grade offers a balance of strength, ductility, and weldability, making them suitable for different industrial needs.
EN10217-1 welded steel tubes are used in a variety of applications, including:
While EN10217-1 provides a range of steel grades, alternative grades may be considered depending on specific requirements. Some possible alternatives include:
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.
