Steel Fabrication in Brisbane Can Be Complicated
Steel fabrications in Brisbane can be a success or a disaster
depending upon the type of steel that you are using. There are several types of
steel alloys available in the market and each of them has different composition
and features that can affect the outcome of a fabrication. Basically, there are
certain factors that you need to check out before deciding over the type of
steel alloy that will need for the fabrication.
One of the
initial issues is the work hardening. Basically, this determines how hard a
fabrication will be after it is cold worked. Different alloys have different
cold hardening rate. For example, the Ferritic steel generally has a lower
hardening rate. On the other hand the austenitic steel has a far higher
hardening rate. There are different methods of hardening. For example, the
austenitic steel can be hardened only through cold work, whereas martensitic
stainless steel can be treated with other methods as well.
Now, this
hardening rate also determines the magnetic permeability, another important
factor in fabrication. Generally, the alloy that has highest work hardening
rate will have the highest magnetic permeability. In fabrication, the forming
speed of an alloy is also a very important factor to consider. The longer the
time needed to get back to the original form, the greater is the chance of
deformation for the alloy.
The next
important thing is the difficulty of machining the alloy. Generally, the
austenitic stainless steel is a problem for most of the operators. In fact, the
difficulty of using machine on this type has given birth to the grade 303 which
is a free machine version.
However, one
must note here that the free machine grades have low corrosion resistance when
compared to the other versions. This is because these versions include non
metallic elements in them and therefore, these alloys should never be used in
corrosive environment like marine exposure. Also, the free machine grades have
high level of sulphur that reduces the ductility of the alloy. So, they should
not be chosen for welded fabrication as well.
