What is bright annealed (BA) stainless hydraulic tube?

Bright annealed (BA) stainless hydraulic tube refers to a type of stainless steel tube that undergoes a specific heat treatment process called bright annealing. This process involves heating the stainless steel tube to a high temperature and then cooling it rapidly in a controlled atmosphere to eliminate internal stresses and improve its mechanical properties.

Bright annealed (BA) stainless hydraulic tube material grade:

BA stainless hydraulic tubes are commonly made from austenitic stainless steel grades such as 304 (1.4301) and 316 (1.4401). These grades offer excellent corrosion resistance, high strength, and good formability, making them suitable for hydraulic applications.

Bright annealed (BA) stainless hydraulic tube surface roughness:

BA stainless hydraulic tubes have a smooth and bright surface finish. The surface roughness is typically specified in terms of Ra (arithmetical mean roughness) or Rz (mean peak-to-valley height). The surface roughness of BA tubes is generally in the range of 0.4 to 0.8 micrometers (µm), providing excellent contact and reducing the risk of corrosion or damage.

Bright annealed (BA) stainless hydraulic tube tolerance:

The dimensional tolerances for BA stainless hydraulic tubes are typically specified by the applicable production standard. These tolerances ensure the tubes dimensional accuracy and allow for proper fit and function in hydraulic systems.

Bright annealed (BA) stainless hydraulic tube advantages:

BA stainless hydraulic tubes offer several advantages, including:

1. Corrosion Resistance: The austenitic stainless steel grades used in BA tubes have high resistance to corrosion, making them suitable for applications where the tube comes into contact with corrosive fluids or environments.

2. High Strength: BA tubes have good mechanical properties, including high tensile strength and yield strength, which ensure their durability and reliability under pressure.

3. Excellent Surface Finish: The bright annealing process provides a smooth and bright surface finish, reducing the risk of surface contamination, corrosion, and wear.

4. Tight Tolerances: BA tubes are manufactured with precise dimensional tolerances, ensuring proper fit and compatibility with hydraulic components.

5. Smooth Surface: The bright annealing process gives the tubes a smooth surface finish, which helps reduce friction and minimize pressure drop in hydraulic systems. It also facilitates easy cleaning and maintenance.
