Steel Grade

The EN10305-1 standard includes several steel grades, primarily E215, E235, and E355. Each grade is tailored for specific applications based on its mechanical properties and chemical composition.

Application

Seamless cold drawn tubes made from these steel grades are widely used in:

• Automotive Industry: For manufacturing components such as axles, shafts, and hydraulic cylinders.
• Machinery: In the production of precision parts that require high strength and durability.
• Construction: For structural applications where high load-bearing capacity is essential.

Possible Alternative Grades

While E215, E235, and E355 are commonly used, there are alternative grades that may be suitable depending on the application requirements:

• S235JR: A general structural steel grade with similar properties.
• S275JR: Offers higher yield strength and is used in structural applications.
• S355J2: Provides improved toughness and is suitable for heavy-duty applications.
