400 Series Stainless Steel Investment Castings

With 11% more chromium and higher carbon content, 400 series stainless steel is a more durable form of the most common variety of stainless steel (300 series). Attributed to its lack of nickel content, 400 series stainless steel is more susceptible to corrosion, though by its nature as a steel alloy, it still retains corrosion-resistant properties.

However, slightly compromising the corrosion resistance gives 400 series stainless steel properties such as higher durability and wear resistance. Additionally, 400 series stainless steel has magnetic properties that are not present in other stainless steel varieties, making it ideal for certain industries and applications. 400 series stainless steel can also be heat treated for additional hardening.

Utilizing high-precision investments, 400 series stainless steel castings produce complex and intricate parts at scale. We can accurately create difficult internal configurations while minimizing material waste. Repeatability and consistency are the hallmarks of our precision investment castings. That is why we are an approved supplier of 400 series stainless steel castings for the aviation, aerospace and energy sectors.

We leverage our knowledge and experience to provide rapid prototyping, shortening lead times and providing both cost and time savings to our customers.
