Stainless Steel Grades We Fabricate
Different projects demand different material properties, which is why our metal fabrication stainless steel services cover a broad spectrum of alloy grades. At precisionvast, we help you select and process the ideal material to ensure your custom parts perform reliably under specific environmental conditions.
Austenitic Stainless Steel (300 Series)
This is the most common group used in stainless steel sheet metal fabrication due to its exceptional formability and corrosion resistance.
- 304 Stainless Steel: The go-to grade for general applications. It offers excellent weldability and formability, making it ideal for 304 stainless steel parts, brackets, and food-grade equipment.
- 316 Stainless Steel: Infused with molybdenum to resist chlorides and harsh chemicals. We use this grade for high-durability 316 marine grade fabrication, pharmaceutical equipment, and outdoor installations.
Ferritic & Martensitic Stainless Steel (400 Series)
These magnetic alloys are selected for applications requiring high strength, hardness, or specific aesthetic finishes.
- Grade 430 (Ferritic): Offers moderate corrosion resistance and excellent formability. Commonly used for appliance panels and automotive trim.
- Grades 410 & 420 (Martensitic): Heat-treatable alloys that deliver high hardness and wear resistance, making them perfect for fasteners, valves, and wear plates.
Duplex Stainless Steel
Duplex grades combine the best properties of austenitic and ferritic steels, offering a mixed microstructure that delivers superior performance.
- High Tensile Strength: Roughly twice the yield strength of 300-series stainless steels, allowing for lighter material thickness and reduced weight.
- Extreme Corrosion Resistance: Highly resistant to stress corrosion cracking and pitting, making it the preferred choice for demanding chemical processing, marine, and oil and gas applications.

FAQs: Metal Fabrication Stainless Steel
What tolerances can we maintain?
We hold tight tolerances across all custom stainless steel fabrication steps to meet your exact specifications.

How do we prevent carbon contamination?
Carbon contamination ruins the corrosion resistance of stainless steel. We prevent this by keeping our SS fabrication services completely separated from carbon steel work. Dedicated tooling: We use separate grinding wheels, brushes, and bending dies reserved only for stainless steel. Clean workspaces: Our fabrication areas are isolated to prevent cross-contamination from airborne carbon dust. Passivation: We offer post-fabrication chemical cleaning to restore the protective chromium oxide layer.
What is the difference between 304 and 316 stainless steel?
Choosing the right grade depends on where you will use the custom metal parts.
- 304 Stainless Steel Parts: The industry standard. Excellent formability and weldability. Perfect for kitchen equipment, structural parts, and general indoor applications.
- 316 Marine Grade Fabrication: Contains molybdenum, which protects against chlorides and harsh chemicals. Best for marine environments, chemical processing, and outdoor industrial use.
Do we provide material certifications (MTRs)?
Yes. We provide full Mill Test Reports (MTRs) upon request. Every batch of steel we source is fully traceable, ensuring you get the exact grade and quality you paid for.
What is our standard lead time?
Our typical lead time for custom stainless steel orders is 2 to 4 weeks. This timeline depends on the complexity of the design, the volume of the production run, and current material availability. We also offer expedited runs for urgent projects.
