Advantages of Steel Casting
1. Greater design flexibility
The designers have the maximum choose freedom to the casting shape
and size, especially complex shape and hollow parts, and steel
castings can be manufactured by the unique process of core castings.
Easy forming and shape change and fast transformation from drawing
to finished product can help offer fast response and shorten
2. Strongest flexibility and variability of metallurgical
You can choose different chemical composition and organization
structure to meet different project requirements. Different heat
treatment process can select mechanical properties and using
properties in a large range and increase weldability and
3. Large overall structural strength
Thus high project reliability, coupled with weight reduction design
and short delivery time, increase competitive advantages in price
4. Large range of change in weight
Small steel castings can be only ten grams, while the weight of
large steel castings can be up to several tons, dozens or even
hundreds of tons.
Compare with forging steel parts:
The anisotropy of steel castings in mechanical properties is not
significant, which is better than forging steel parts. The designers
often have to consider materials performance in the three coordinate
axis during some high-tech products design, thus the advantages of
steel castings deserve to be taken seriously. Steel castings,
regardless of the weight, volume, and batch, are easily to make
complex shape and non-significant stress concentration parts.
Compare with the welded structure:
In shape and size, the welded structure flexibility is better than
forging steel parts, but compared with steel castings, there are
still the following shortcomings:
1). It is easy to deformation during welding process.
2). It is difficult to make a streamlined shape.
3). Internal stress is high during welding process.
4). Welding seam is bad to the appearance and reliability of parts.
Compare with iron casting and other alloy casting:
Steel castings can be used for a variety of working conditions, and
the mechanical properties are superior to any other alloy castings.
When we need high tensile stress or dynamic load parts, important
pressure vessel castings, and key parts bearing heavy load in low or
high temperatures, in principle, we should give priority to use
However, the vibration absorption, abrasion resistance, and mobility
of steel castings are worse than iron castings, in addition, the
costs are higher than iron castings.
