CF8 Stainless Steel: The Optimal Choice for Investment Casting

The creation of durable and high-performing products relies heavily on the materials used. This is particularly true in the manufacturing industry where the integrity and efficiency of a product can be linked directly to the quality of its components. A shining example of superior material choice is CF8 stainless steel, especially when used in investment casting.

What is CF8 Stainless Steel?

CF8 Stainless Steel, also known as 304 Stainless Steel in AISI standard, is a versatile and widely used material due to its excellent resistance to a wide range of environments. It contains 18% Chromium and 8% Nickel, contributing to its impressive corrosion resistance and mechanical properties.

The following table provides the chemical compositions and mechanical properties of CF8 stainless steel.

Understanding the Investment Casting Process


Investment casting, also known as lost-wax casting, is a manufacturing technique that has been used for centuries. Over time, it has been refined to meet modern standards and needs, thus playing a pivotal role in the production of high-precision and complex parts.

The investment casting process begins with the creation of a wax pattern. This pattern is an exact replica of the final product. It is then covered in a refractory material, forming a ceramic shell. Once this shell hardens, the wax is melted and drained, leaving a hollow mold.

The mold is then preheated to withstand the molten CF8 stainless steel that is poured into it. After cooling and solidifying, the ceramic mold is broken away, revealing a part that retains the exact dimensions of the original wax pattern.

Investment casting excels in producing parts with exceptional surface finish and dimensional accuracy. It is ideal for making complex parts that require tight tolerances and minimal machining. CFS Foundry is the professional manufacturer that employs this process to achieve superior results.

Examples of CF8 Stainless Steel Components By Investment Casting

CFS Foundry has an extensive portfolio of CF8 stainless steel components made by the investment casting process. These range from industrial machinery parts, automotive components, to medical equipment.

CF8 Stainless Steel Cast Impeller

For instance, one of the components CFS Foundry specializes in is stainless steel impellers for pumps. These impellers, made from CF8 stainless steel through investment casting, exhibit high corrosion resistance, ensuring a long service life even in demanding conditions.

Another example is the manufacture of precision parts for the automotive industry. The exceptional dimensional accuracy provided by the investment casting process means that components such as gear shifters, levers, and engine parts can be produced with exacting precision, eliminating or significantly reducing the need for secondary machining.

Why Choose CF8 Stainless Steel for Investment Casting?

There are several compelling reasons why CF8 stainless steel is the optimal choice for investment casting.

Firstly, CF8 stainless steel has excellent fluidity, making it ideal for the casting process. This ensures that the molten metal fills the mold evenly, capturing intricate details accurately.

Secondly, the impressive corrosion resistance of CF8 stainless steel enhances the lifespan of the components, reducing maintenance and replacement costs. It also withstands a wide range of temperatures, making it suitable for components used in high-temperature applications.

Lastly, the mechanical properties of CF8 stainless steel, including its tensile strength and yield strength, make it a reliable material choice for high-stress applications.
