Common Stainless Steel Grades We Machine Daily
When choosing stainless steel CNC machining services, knowing the right alloy for your part is critical. At MS Machining, we work daily with a broad range of stainless steel grades to deliver precision, durability, and performance tailored to your application.
Stainless Steel Grades We Commonly Machine
- 303: Excellent machinability, used for intricate parts requiring easy cutting.
- 304 / 304L: The most popular general-purpose stainless steel, great corrosion resistance, food-grade safe.
- 316 / 316L: Superior corrosion resistance, especially in marine and chemical environments; FDA compliant.
- 17-4PH: High strength and hardness, often used in aerospace and defense.
- 15-5PH: Similar to 17-4PH but offers better corrosion resistance.
- 440C: High carbon stainless with excellent hardness and wear resistance.
- 420: Good corrosion resistance and high hardness, common in cutlery.
- Dubbelslag 2205: Combines high strength with excellent corrosion resistance, ideal for harsh environments.

|---|---|---|---|
| 303 | Utmärkt | Screws, bolts, fittings | Highly machinable, less corrosion resistant |
| 304 / 304L | Bra | Food processing, medical parts | FDA compliant, corrosion resistant |
| 316 / 316L | Måttlig | Marine parts, chemical industry | Superior corrosion resistance, FDA approved |
| 17-4PH | Måttlig | Aerospace, defense components | High strength, heat treatable |
| 15-5PH | Måttlig | Aerospace, medical devices | High strength, better corrosion resistance |
| 440C | Svårt | Valve parts, high-wear tools | High hardness, wear resistant |
| 420 | Måttlig | Cutlery, surgical instruments | Good hardness and corrosion resistance |
| Dubbelslag 2205 | Svårt | Oil & gas, marine equipment | High strength & corrosion resistance |
*Machinability rating is relative; “Excellent” means easier cutting with faster speeds, “Difficult” means slower feeds and more wear on tools.

For projects requiring extra validation, we offer First Article Inspection (FAI) and Production Part Approval Process (PPAP) reports upon request. These quality control tools help you meet regulatory and customer standards smoothly.
With these certifications and rigorous processes, you can trust MS Machining to deliver reliable, precision CNC machined stainless steel components every time.
Lead Times & Production Volumes
We offer fast turnaround times tailored to your project size. Prototype parts typically ship within 3–7 dagar, perfect for quick design validations. For low-volume orders, expect delivery in 2–3 weeks, ideal for pilot runs or small batch needs. Larger production runs usually take 4–8 weeks, depending on complexity and quantity. Need parts faster? We provide expedite options to meet tight deadlines without sacrificing quality. Whether you’re testing a prototype or scaling up, our stainless steel CNC machining services flex to fit your schedule.
Cost Drivers in Stainless Steel Machining (How to Save Money)
Saving money on stainless steel CNC machining starts with smart design choices. Here are some key tips to help you lower costs without sacrificing quality:
-
Design för tillverkningsbarhet (DFM): Keep your designs straightforward and avoid overly complex features that require special tooling or extra steps. We offer free DFM feedback within 24 hours to help optimize your parts for cost-effective production.
-
Avoid Unnecessary Tight Tolerances: Tighter tolerances increase machining time and inspection efforts. Reserve precise tolerances only where absolutely needed. Loosening some specs can reduce costs significantly.
-
Material Selection Matters: Different stainless steel grades vary in machinability and price. For example, 303 machines easier (and cheaper) than 316 or duplex stainless. Choosing the right grade based on your application can cut material and machining costs.
By considering these factors early, you get reliable, cost-efficient parts tailored to your needs. For more insights on how we handle challenging alloys while controlling costs, check out our detailed tillverkar komponenter av rostfritt stål sida.
How to Get a Fast, Accurate Quote from MS Machining
To get a quick and precise quote for your stainless steel CNC machining project, send us your design files in common formats like STEP, IGES, SolidWorks, or PDF drawings. The more detailed your files, the faster we can review and price your job.
Along with your files, please include key information such as:
- Desired quantity and production volume
- Material grade (if known)
- Required tolerances and surface finish
- Any special processes or certifications needed
With these details, we typically provide a quote within the same day to 24 hours, helping you move your project forward without delay.
