Stainless Steel Castings Materials
Stainless Steel 304
As a kind of steel with a wide range of uses, it has good corrosion resistance, heat resistance, low-temperature strength, and mechanical properties. Stamping, bending and other thermal processing, no heat treatment hardening phenomenon. No magnetic can be well used in temperature -196℃~800℃.

Advantages of Stainless Steel Castings
1. Greater design flexibility
This design has the maximum freedom to choose the shape and size of castings, especially complex shapes and hollow sections, and steel castings can be manufactured by a unique process of core castings.
Easy to shape and change shape and can be quickly made according to the drawing can provide fast response and shorten the delivery time.
2. Maximum flexibility and variability in metallurgical manufacturing
You can choose different chemical components and organizational structures to meet the needs of different projects. Mechanical properties can be selected for different heat treatment processes and this property can be used in a wide range to improve weld-ability and usability.
3. Improve the overall structural strength
High project reliability, coupled with light-weight design and shorter lead times, can improve competitive advantage in terms of price and economy.
4. Wide range of weight changes
Small steel castings may be as little as 10 grams, while large steel castings can be several tons, tens or even hundreds of tons.
Compared to forged steel parts:
The mechanical properties of steel castings produced by foundries differ little in all directions and are superior to forged steel parts.
When designing some high-tech products, designers must consider the properties of materials in three directions, which highlights the advantages of castings.
Steel castings are easy to make complex shapes and non-stress-concentrated parts, regardless of weight, volume, and quantity produced at a time.
Compared with the welded structure:
In terms of shape and size, welded structures are more flexible than forged steel parts, but still have the following disadvantages compared to steel castings:
1) Prone to deformation during welding.
2) It is difficult to form a streamlined structure.
3) High internal stress during welding.
4) Welds affect the appearance and reliability of components.
Compared with iron casting and other alloy castings:
Steel castings can be used in a variety of working conditions and have better mechanical properties than other alloy castings.
In principle, we should give priority to steel castings when we need high tensile strength or dynamic loading components, important pressure vessel castings, and core components that bear heavy loads at low or high temperatures.
However, steel castings are not as good as iron castings in terms of vibration absorption, wear resistance and mobility, and they cost more than iron castings.
