FAQs
1. What is EN 10305?
EN 10305 is a European standard that tubes meet strict requirements for mechanical properties, such as tensile strength, yield strength, and dimensional tolerances, guaranteeing reliable performance in critical applications.
2. What is the difference between EN 10305-1 and EN 10305-4?
EN 10305-1 and EN 10305-4 are two distinct parts of the EN 10305 standard, each serving different purposes:
- EN 10305-1: This part focuses on the dimensional accuracy and tolerances for precision steel tubes. It specifies requirements for outside diameter, wall thickness, and length, ensuring that the tubes meet precise measurements necessary for various applications.
- EN 10305-4: In contrast, this part is dedicated to seamless cold-drawn precision steel tubes specifically intended for hydraulic and pneumatic systems. It emphasizes not only dimensional accuracy but also the chemical composition, mechanical properties, and surface quality of the tubes.
3. What is the chemical composition of EN 10305?
The chemical composition of EN 10305 steel tubes varies based on the grade and specific application but generally includes carbon (C), manganese (Mn), phosphorus (P), sulfur (S), and other elements such as silicon (Si), chromium (Cr), or nickel (Ni). These elements provide the required mechanical properties like strength, durability, and resistance to corrosion. The exact composition is tailored to meet the performance demands of different industries, including automotive, hydraulic, and mechanical applications, while adhering to the EN 10305 standard.
