Hydraulic Steel Tubes - ST37.4 Material
High quality carbon steel hydraulic tubing in
material ST 37.4 NBK, according to DIN 2391
EN10305. Annealed and phosphated.
 CODE
NO.: DIN2391-ST37.4
Cold Drawn Seamless Steel Hydraulic Tubing
-
DIN highly accurate, cold drawn seamless
and bright seamless hydraulic tubes
is used as the tube to be phosphated. The phosphated is realized
with the imported chemical fluid to form a black film. The antirust
oil is absorbed by means of the micropore on the film to prevent
from the rust. The caps are covered at two ends of tube to prevent
from the dust.
-
High accuracy, excellent brightness, no
oxidization on the outer and inner walls after heat treatment,
high cleanness inside wall.
-
The steel tube is able to stand high pressure.
No deformation after cold bending, no crack after flaring and
flattening. The complicated geometrical forming and machining
can be realized.
-
The color of NBK tube is Bright Black.
Color is homogeneously distributed on the tube surface. The
tube has good property of antirust.
