Steel Grade

DIN 2391 ST52 E355 tubing falls under the steel grade ST52, which is a low-alloy, high-strength structural steel. This particular grade offers excellent mechanical properties, including high tensile and yield strength, making it ideal for hydraulic tubing applications requiring robustness and reliability.

Application

DIN 2391 ST52 E355 tubing is commonly used in a wide range of high-pressure hydraulic applications, including:

1. Hydraulic cylinders: The tubing is ideal for manufacturing hydraulic cylinders due to its high strength, pressure resistance, and honed surface finish.
2. Hydraulic systems: It is used in hydraulic systems that require seamless tubing capable of withstanding heavy loads and extreme pressure conditions.
3. Automotive industry: The tubing can be found in various automotive components, such as steering systems, suspension systems, and brake systems.
4. Industrial machinery: It is also widely utilized in industrial machinery, such as hydraulic presses, lifts, and machine tools.

Possible Alternative Grades

While DIN 2391 ST52 E355 tubing offers exceptional performance, there are alternative grades that can be considered for specific applications. Some possible alternatives include:

1. ASTM A519 Grade 1026: This carbon steel tubing provides similar properties to ST52, suitable for hydraulic systems operating under high pressure.
2. DIN 17121 Grade St52-3: Another alternative grade that offers good strength and high pressure resistance in hydraulic applications.
3. ASTM A106 Grade B: Although primarily used for high-temperature applications, it can also be used as a substitute for ST52 in certain high-pressure hydraulic systems.
