EN10216-1 is a European standard that specifies the requirements for seamless steel tubes intended for pressure purposes. These tubes are widely used in industries such as oil and gas, petrochemical, and power generation due to their ability to withstand high pressure and temperature conditions. The standard covers several steel grades, including P195TR1 (1.0107), P195TR2 (1.0108), P235TR1 (1.0254), P235TR2 (1.0255), and P265TR1 (1.0258).
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 (1.0107) | P195TR2 (1.0108) | P235TR1 (1.0254) | P235TR2 (1.0255) | P265TR1 (1.0258) |
|---|---|---|---|---|---|
| Carbon (C) | ≤ 0.17 | ≤ 0.17 | ≤ 0.16 | ≤ 0.16 | ≤ 0.20 |
| Manganese (Mn) | ≤ 1.20 | ≤ 1.20 | ≤ 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) | ≤ 0.35 | ≤ 0.35 | ≤ 0.35 | ≤ 0.35 | ≤ 0.35 |
The mechanical properties of these steel grades determine their suitability for various applications. The table below outlines the typical mechanical properties:
| Property | P195TR1 (1.0107) | P195TR2 (1.0108) | P235TR1 (1.0254) | P235TR2 (1.0255) | P265TR1 (1.0258) |
|---|---|---|---|---|---|
| Tensile Strength (MPa) | 320 - 440 | 320 - 440 | 360 - 500 | 360 - 500 | 410 - 570 |
| Yield Strength (MPa) | ≥ 195 | ≥ 195 | ≥ 235 | ≥ 235 | ≥ 265 |
| Elongation (%) | ≥ 25 | ≥ 25 | ≥ 25 | ≥ 25 | ≥ 22 |
The steel grades covered under EN10216-1 are designed to meet specific requirements for pressure applications. Each grade offers a balance of mechanical properties and chemical composition to suit different industrial needs.
EN10216-1 seamless steel tubes are used in a variety of applications, including:
Depending on the specific requirements of an application, alternative grades may be considered. These could 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.
