Disadvantages of Cast Steel Parts
One of the advantages of cast steel parts is flexible
design. Designers have the largest design choice on the shape
and dimensions of cast steel parts. Especially complex shape and
hollow section parts, we could manufacture cast steel parts with
set core special technology.
Secondly, the manufacturing flexibility and variability of cast
steel parts is strongest. We can choose different chemical
composition and organization control, adapted to different
engineering requirements. We could also choose mechanical
property over a wide range of selection by different heat
treatment process with good weldability and workability.
Thirdly, the material of cast steel parts is isotropic and the
overall constitutive property is strong, thus improves the
reliability. And for its small weight and short lead time, it
has great advantages on pricing.
Finally, the weight of cast steel parts could be over a wide
range of changes, ranging from a few grams to hundreds of tons.
Comparing with welding parts
In terms of shape and size, the flexibility of welding structure
parts is better than forged steel parts, but compared with
steel, still has the following disadvantages:
1) The welding structure parts are easy to be out of shape.
2) It is difficult to make a streamlined shape.
3) High stress in the welding process
Of course, welding structure parts also have the advantage of
short lead time. Comparing with cast steel parts, there is no
need to make mould.
Compared with cast iron parts and other alloy castings
Cast steel parts can be used for a variety of different
conditions, the comprehensive mechanical performance is better
than that of any other casting alloy.
Cast steel could be made to different parts like withstand high
tensile stress or dynamic load parts, important pressure vessel
casting parts, under the low temperature or high temperature
parts, bear large load parts.
But the vibration absorption, abrasion resistance, liquidity and
casting performance of cast steel parts is all worse than that
of cast iron parts. And the production cost of cast steel parts
is also higher than cast iron parts.
