EN 10217-7 Common Steel Grades and Equivalent AISI Grades
| EN 10217-7 Steel Grade | Equivalent AISI Grade | Material Type | Key Characteristics |
|---|---|---|---|
| 1.4301 | 304 | Austenitic Stainless Steel | Excellent corrosion resistance, good formability, and weldability. Suitable for general use. |
| 1.4306 | 304L | Austenitic Stainless Steel | Low carbon version of 1.4301, ideal for welding applications to avoid carbide precipitation. |
| 1.4401 | 316 | Austenitic Stainless Steel | Enhanced corrosion resistance due to molybdenum content, suitable for marine and chemical environments. |
| 1.4404 | 316L | Austenitic Stainless Steel | Low carbon version of 1.4401, excellent for welding and high-corrosion environments. |
| 1.4541 | 321 | Austenitic Stainless Steel | Stabilized with titanium, resistant to intergranular corrosion, ideal for high-temperature applications. |
| 1.4462 | 318LN / 2205 | Duplex Stainless Steel | High strength, excellent corrosion resistance, and good weldability. Suitable for aggressive environments. |
| 1.4539 | 904L | Austenitic Stainless Steel | High nickel and molybdenum content, excellent resistance to sulfuric acid and chloride stress corrosion. |
| 1.4571 | 316Ti | Austenitic Stainless Steel | Stabilized with titanium, resistant to intergranular corrosion, suitable for high-temperature applications. |
Tolerances on Outside Diameter (OD)
The outside diameter (OD) tolerances for tubes depend on the manufacturing process (e.g., cold-formed or hot-formed) and the size of the tube. Below are the general tolerances based on EN 10217-7:
| Tube OD (mm) | Tolerance (Cold-Formed Tubes) | Tolerance (Hot-Formed Tubes) |
|---|---|---|
| ≤ 30 | ±0.20 mm | ±0.50 mm |
| 30 < OD ≤ 114 | ±0.50 mm | ±1.00 mm |
| 114 < OD ≤ 219 | ±0.75 mm | ±1.50 mm |
| 219 < OD ≤ 508 | ±1.00 mm | ±2.00 mm |
| > 508 | ±1.00% of OD | ±1.50% of OD |
Notes:
- Cold-formed tubes generally have tighter tolerances compared to hot-formed tubes.
- For large-diameter tubes (e.g., > 508 mm), tolerances are expressed as a percentage of the OD.
Technical Grades and Delivery Conditions
The EN 10217-7 standard classifies pipes based on Technical Class and Delivery Condition. Here’s a detailed explanation:
Technical Class (TC)
-
TC1 (Technical Class 1): Suitable for general purposes, with lower testing requirements and no need for full non-destructive testing.
-
TC2 (Technical Class 2): Suitable for more demanding applications, requiring full non-destructive testing for higher quality assurance.
-
TC3 (Technical Class 3): Suitable for the most critical applications, often used in high-pressure, high-temperature environments or critical equipment.
Delivery Condition (DC)
-
D3 (Delivery Condition 3): Pipes are delivered in the as-welded condition, typically without additional heat treatment.
-
T3 (Heat Treatment Condition 3): Pipes undergo solution annealing to eliminate welding stress and improve corrosion resistance and mechanical properties.
Whether you need TC1, TC2, or TC3 grade stainless steel welded pipes, we can provide solutions tailored to your requirements.
