EN 10277-2 is a European standard that specifies the requirements for cold-rolled stainless steel bright tubes used in general engineering applications. This standard ensures the quality and properties of the steel tube, making it suitable for various industries. In this article, we will explore the material, specification, key features, chemical composition, mechanical properties, steel grades, applications, and possible alternative grades for EN 10277-2 cold-rolled steel tubes.
EN 10277-2 cold-rolled steel tubes are manufactured from stainless steel, which provides excellent corrosion resistance and durability. Stainless steel is chosen for its ability to withstand high temperatures and harsh environments, making it ideal for engineering applications that require reliable performance.
The specification for EN 10277-2 cold-rolled steel tubes includes criteria for its dimensions, tolerances, surface finish, and mechanical properties. Compliance with this specification ensures that the tubes meet the required standards and can perform effectively in their intended applications.
The key features of EN 10277-2 cold-rolled steel tubes are:
| Element | Percentage Range |
|---|---|
| Carbon (C) | 0.03% max |
| Silicon (Si) | 1.00% max |
| Manganese (Mn) | 2.00% max |
| Phosphorus (P) | 0.045% max |
| Sulfur (S) | 0.015% max |
| Chromium (Cr) | 16.0-18.0% |
| Nickel (Ni) | 10.0-14.0% |
| Nitrogen (N) | 0.10% max |
| Property | Value |
|---|---|
| Tensile Strength (Rm) | 500-700 MPa |
| Yield Strength (Rp0.2) | 200-400 MPa |
| Elongation (A) | 35-50% |
| Hardness (HB) | 150-250 HB |
| Impact Value (KV) | 100 J min |
EN 10277-2 defines different steel grades, including X5CrNi18-10, X8CrNiS18-9, X2CrNiMo17-12-2, and more. These steel grades have varying chemical compositions and mechanical properties to cater to specific engineering requirements.
EN 10277-2 cold-rolled steel tubes find application in various general engineering sectors, including but not limited to:
If alternative grades are required, several options can be considered depending on specific needs. Some possible alternatives to EN 10277-2 cold-rolled steel tubes include ASTM A213/A269 stainless steel tubes, DIN 17457 stainless steel tubes, and JIS G3448 stainless steel tubes. However, it is essential to consult the specific requirements and evaluate the suitability of alternative grades before making a selection.
