Stainless Steel
Stainless Steel Custom Machined Parts
Tamshell has partnered with customers for decades to produce close-tolerance stainless steel components that meet demanding performance standards and tight specifications.
Our long-standing experience allows us to understand the complexities of precision machining and deliver consistent, high-quality results across a wide range of applications.
Stainless steel delivers the perfect balance of strength, precision, and reliability. Its excellent machinability, weldability, and formability make it ideal for complex, high-performance parts—ensuring every component meets exact specifications with lasting durability and corrosion resistance.
We machine the following grades of Stainless.
| Stainless Grade | Description of grades of Stainless Steel. |
|---|---|
| 302 | SS 302 is an austenitic chromium-nickel alloy that offers good corrosion resistance, strength, and ductility. Its tensile strength ranges between 100–200 ksi. It offers good formability, weldability, and ductility. |
| 303 | Grade 303 stainless steel is a unique kind of stainless steel. It is made from chromium, nickel, and other elements, making it highly resistant to corrosion and heat. It also has high strength and excellent machinability characteristics. |
| 304 | Type 304 has good processability, weldability, corrosion resistance, heat resistance, low temperature strength, and mechanical properties. It is an austenitic stainless steel, and is therefore not magnetic. |
| 316 | 316 Stainless Steel is a versatile and widely used material known for its excellent corrosion resistance and high strength. It is a member of the austenitic stainless steel family and primarily consists of chromium, nickel, and molybdenum. |
| 321 | AISI 321 stainless steel (SS321) is basically type 304 with the addition of titanium (Ti), which stabilizes carbides against sensitization to prevent intergranular precipitation of chromium carbide when the steel is heated to a temperature within the sensitization range. |
| 347 | 347 stainless steel is a high-carbon steel with a minimum chromium content of 12%. Like any other stainless steel, grade 347 can also be hardened through heat treatment. It offers good ductility in its annealed state and excellent corrosion resistance properties when the metal is polished, surface grounded or hardened. |
| 410 | 410 stainless steel is a general-purpose martensitic stainless steel that provides increased strength and hardness relative to Type 410, with moderate corrosion resistance. It is magnetic in both the annealed and hardened conditions. |
| 416 | 416 stainless steel is martensitic stainless steel that contains 12-13% chromium. It has good machinability but poor weldability due to the high sulfur content. It is magnetic in all conditions. |
| 420 | 420 stainless steel is a high-carbon steel with a minimum chromium content of 12%. Like any other stainless steel, grade 420 can also be hardened through heat treatment. It offers good ductility in its annealed state and excellent corrosion resistance properties when the metal is polished, surface grounded or hardened |
| 430 | 430 stainless steel is a non-hardenable steel containing straight chromium, and belongs to the ferritic group of steels. This steel is known for its good corrosion resistance and formability, coupled with practical mechanical properties. |
| Machinability | All the above grades are within the Tamshell machinability index. |
DO WE MACHINE ALL STAINLESS GRADES?
The short answer is…
Tamshell is capable of machining nearly all stainless steel grades, allowing flexibility across a wide range of applications. However, material choices aren’t one-size-fits-all.
Factors like hardness, machinability, and the specific use of the part all influence whether a certain grade is the best fit for production. By taking these into account, Tamshell can help ensure the selected material performs as intended while maintaining efficient and consistent machining.
