HYDRAULIC CYLINDER TUBE – ST 52.3 – SSID

Hydraulic Cylinder Tube ST 52.3             Typical Chemical Analysis
with excellent machinability and             Carbon                 0.20%
weldability.   Supplied    electro-          Silicon                0.50%
welded and drawn (BK), with yield
strength over 500 MPa. The special           Manganese              1.50%
smooth inside diameter (SSID) is             Phosphorus         0.050% max
ready to use and is oiled with the           Sulphur            0.050% max
tube ends capped for protection.

Description: SSID is the acronym for Service Set Identifier. SSID of a wireless LAN technology can be divided into several different authentication needs of sub-networks, each subnet requires a separate authentication, only authenticated users can access the corresponding sub-networks to prevent unauthorized users access to the network.
