ASTM A 519 Seamless mechanical tubing is manufactured from carbon and alloy steels for structural or other mechanical purposes involving machining or heat treating, where close tolerances, smooth finish, or definite physical properties are important factors. It is a cost effective alternative to DOM steel tubing.

The ASTM A519 Grade 1026 tube is usually manufactured by hot working
steel. The hot worked steel manufactured under this specification could either
be carbon steel or this process could be used to make the ASTM A519 1026
Chrome Alloy Steel Hf Smls Tubing. If necessary, the Chrome Moly Steel ASTM
A519 1026 Boiler Tubing could be subsequently cold finished by hot working
the tubular product. Hot working the Alloy Steel ASTM A519 1026 Square
Tubing in order to produce the desired dimensions, shape as well as certain
properties.
The specified ASTM A519 Grade 1026 tubes, are generally furnished in the
following shapes i.e. rectangular, round or square. If required, At Aesteiron,
we manufacture these ASTM A519 Grade 1026 Mechanical Tubing furnished
in special sections, according to the need of our clients or if required by the
application for which it is to be used for. Heat analysis is usually performed
on the ASTM A519 Grade 1026 Steel Tubing in order to determine the
percentages of the elements specified in the material used to make these
tubes. Although If secondary melting processes are used in the melting of A519
gr 1026 Seamless Tubing, the heat analysis could be obtained either from one
re-melted ingot or the product of one re-melted ingot of every single primary
melt. The ASTM A519 1026 Hot Finished Tubing has to be coated with a film
of oil before shaping to retard rust when specified

ASTM A519 SAE1026 seamless tubing cold drawn process
Grade Summary: DOM Steel Tube is typically produced using uniformly high
quality C1026 steel strip which is formed and electric resistance welded into its
basic shape. What makes DOM different to ERW Tube is that after annealing to
produce a uniform grain structure throughout, the tube is then cold drawn over a
mandrel to give it uniform shape, close wall tolerances and high physical
properties. The cold working process also works the weld area to produce a weld
line that virtually disappears, causing DOM tube to appear seamless.
Typical Applications: Mechanical, hydraulic cylinders, shaft, tight tolerance
requirements
