Stainless Steel Casting
Lestercast manufacture castings in a wide range of metals and alloys. Stainless steel is hugely popular in the production of investment casting components across all industries.
Stainless steel is notably one of the most versatile materials used in the manufacturing industry, specifically relating to castings. Used in many applications, stainless steel is widely used throughout the food, marine, safety and automotive industries.
Lestercast have been manuafacturing stainless steel investment castings for companies across a wide range of industries for over 50 years. We pride ourselves on quality and reliability, and are proud to supply the most prestigious manufacturers and suppliers with high quality castings around the world.
We are proud members of the Cast Metals Federation, accredited with the automotive specification IATF 16949:2016 & Quality Management Specification ISO 9001:2015, and also have Fit for Nuclear (F4N) status.
Please take a look below for more information on the properties of stainless steel and its most common cross-sector uses.
Properties of Stainless Steel
Stainless Steel’s main component is Iron. As a naturally sourced metal, Iron needs to be fully cleared of its impurities to create a workable alloy. Another key component of Stainless Steel is Chromium. When Chromium is partnered with Iron it increases the resistance that stainless steel will have relating to corrosion and wearing.
At Lestercast, we are able to investment cast a large range of stainless steels for your project requirements. Please see the list at the bottom of the page detailing the different grades, and contact us if the particular grade you require is not listed.

Bentley Motors’ Case Study – ‘The Flying B’….
Lestercast have proudly been manufacturing the iconic ‘Flying B’ on behalf of Bentley Motors, using investment casting techniques, for over 14 years.
The upright bonnet mascot is a stainless steel investment casting, now on it’s sixth iteration, with the latest being the most complex, having crystal wings which illuminate as part of the lighting welcome sequence.
This Case Study, written by Bentley Motors gives an insight into the investment casting process and the manufacture of the ‘Flying B’.
When Bentley Motors asked to film the manufacturing of the ‘Flying B’ at Lestercast, we were only too pleased to oblige….
Types of Stainless Steel Alloys
With the various types of stainless steel, to include:
- Duplex – ASTM A890 4A, ASTM A890 6A, ASTM A995 4A, ASTM A995 5A, ASTM A995 6A.
It is important to consider the use for the final end product when selecting the correct type and it’s forward usage.
For certain types of Stainless Steels, heat treatments such as precipitation hardening are available to improve strength and hardness.
Industrial use of Stainless Steel
Stainless steel castings are very versatile. In other words, they can be used in many sectors in a multitude of applications. We work into many sectors with stainless steel for example:
- Culinary uses
- Food machinery
- General engineering
- Home applications and appliances
- Medical Equipment
