Steel Casting Service

Steel casting is a manufacturing process which pouring molten steels to customized mold and let them solidify to required shape. Usually, steel casting is used to produce high-volume complex parts or components. Precision metal casting can produce high accuracy parts. 

In most occassion, casting parts need further process to achieve required dimension or structure. CNC machining is the key to realize the precision metal casting.

What is steel castings?

Steel castings refer to the parts which made of cast steel. The performance of steel castings is similar to cast iron, but stronger than cast iron. Steel castings are prone to shortcomings such as pore defects and inaccurate angular positioning during the casting process. And the casing may break during the long-term using.


Advantages of steel castings

1. Greater design flexibility

This design has the greatest freedom to choose the shape and size of the casting, especially the complicated shape and hollow part. The steel casting can be manufactured by the unique process of the core casting. It's easy to make shape and change shape, and the finished products can be produced quickly  according to drawings. In this way, we can provide quick response and shorten delivery time.

2. The strongest flexibility and variability in metallurgical manufacturing

You can choose different chemical compositions and organizational structures to meet the needs of different projects.  The mechanical properties can be selected via different heat treatment processes, and this property  can be used in a wide range.  And the solder-ability and usability could be improved in the meantime.

3. Improve overall structural strength

Due to the high reliability of the project, coupled with the weight reduction design and short delivery time, it can increase the competitive advantage in terms of price and economy.

4. Wide range of weight changes

Small steel castings may have 10 grams only, while large steel castings can reach several tons, dozens or even hundreds of tons.


2. Disadvantages

(1) Uneven organization.

(2) The organization is not dense.

(3) The surface is rough.

(4) Higher cost and time-consuming.


Common defects

The common process defects including pores, inclusions, shrinkage, porosity and cracks.

The main defects of steel castings are fatigue cracks, including mechanical fatigue cracks and thermal fatigue cracks.
