DIN2391 E235 WT15 Seamless Steel Tube Black Phosphated With Good Mechanical Performance

DIN2391 Cold Drawn Precision Steel Tube Black Phosphated Welded Hydraulic Steel Tubes

Description:

DIN2391 Cold Drawn Precision Steel Tube Black Phosphated Welded Hydraulic Steel Tubes are meticulously crafted components designed for high-performance hydraulic systems. These tubes, known for their precision and durability, undergo a specialized cold drawing process to ensure exceptional strength and resilience. The black phosphated finish not only enhances corrosion resistance but also provides a sleek appearance. With seamless welds and superior craftsmanship, these tubes deliver reliable performance in demanding industrial applications, making them a preferred choice for hydraulic systems worldwide.

Delivery Condition:

The tubes can be produced in the following delivery conditions:

GBK (+A) Annealed.

After the final cold forming process the tubes are annealed in a controlled atmosphere.

NBK (+N) Normalized. (Mainly focus on)

After the final cold forming process the tubes are annealed above the upper transformation point.

BK (+C) Cold finished/hard (cold finished as drawn).

No heat treatment after the last cold forming process.

BKW (+LC) Cold finished/soft (lightly cold worked)

After the last heat treatment there is a light finishing pass (cold drawing).

BKS (+SR) Cold finished/stress relieve annealed.

After the final cold forming process the tubes are stress relieve annealed.
