Stainless Steel CNC Machining Parts
With the challenges of high hardness of the material, strict processing requirements, high precision and strong corrosion resistance, Yecheng ensures accuracy, on-time delivery and your budget.
Compared to aluminum and ordinary steel, stainless steel CNC machining parts can withstand greater loads, pressures and wear, and have a more robust and durable structure after processing.
By adopting appropriate processing techniques, you can obtain stainless steel CNC machining parts with smooth surfaces and low residual stress.
Stainless steel CNC machining parts are indispensable in fields that have strict requirements for strength, precision, corrosion resistance, hygiene and reliability.
Stainless steel CNC machining parts are resistant to rust and damage, and do not require frequent maintenance and replacement after installation.
After CNC machining, there are many choices for you to do surface treatment like plating, polishing, mirror polishing, PVD, further enhancing their corrosion resistance.
Stainless steel is a green and environmentally friendly material. The waste generated from CNC processing can be 100% recycled and reused.
Professional Tools Inventory
After 12 years of in-depth research in stainless steel CNC machining parts, we have developed a dedicated processing parameter library for various stainless steel grades (such as 304, 316, 303, 17-4PH).
From tool selection, spindle speed and feed rate to cooling strategies, we have optimized every aspect to effectively prevent hardening during processing, extend the lifespan of the tools, and fundamentally ensure your processing efficiency and the surface quality of your stainless steel CNC machining parts.
Cost-Saving Machining Strategies
Unlike most factories that have advantages in aluminum machining, Yecheng has more experience in stainless steel CNC machining parts. We have many methods to enhance our processing efficiency.
We can use advanced 3-axis CNC machines to replace 5-axis machines, which greatly reduces about 20-30% cost. You don’t need to pay extra for complex programming. At the same time, you can get consistent quality and fast turnaround that meets the strict tolerance requirements in your drawings for your stainless steel CNC machining parts.
Quality Control for Stainless Steel CNC Machining Parts
From raw material inspection to CNC processing inspection, we ensure every process is under control. For stainless steel CNC machining parts prone to deformation, we adopt the “stress relief process” and special fixtures to ensure the shape stability after processing to the greatest extent.
Besides, we have Hexagon CMM, profilometer and surface roughness meter. We can not only provide the testing report for stainless steel CNC machining parts, but also fully meet your quality standards.
Our Workshop for Stainless Steel CNC Machining Parts
Professional CNC machine centers and quality control measurement system ensure the tolerance and quality of stainless steel cnc machining parts.
Customized Stainless Steel CNC Machining Parts Project
Professional CNC machine centers and quality control measurement system ensure the tolerance and quality of stainless steel cnc machining parts.
With an inner hole tolerance of ±0.01mm, it can be adapted to a 0.5mm pen core.We adopted CNC precision machining process, achieving a delivery volume of 500,000 pieces within three months. This helped its flagship product become a hit, with a component failure rate of only 0.03%, far exceeding the industry standard.
CNC milling ensures the flatness of the sealing surface. The nickel plating process achieves 1000-hour salt spray protection. Our CNC flexible production line can deliver custom nuts and bolts prototype within 7 days. With stable quality, we have become their core supplier, enabling the safety upgrade of their products.
The robotic mechanical arm has strict requirements for transmission accuracy. We select SUS440C stainless steel to process the core transmission shaft. Using imported Japan equipment for micro-micron precision milling, the surface roughness reaches Ra1.6μm, ensuring smooth operation under high load conditions.
Comparison of Stainless Steel Types
The following is a comparison table of the main types of stainless steel, material characteristics, and the CNC machining properties for your reference.
- Comparison Table
| Stainless Steel Type | Typical Grade | Main Alloy Composition | Corrosion Resistance | Mechanical Properties | Heat Treatment |
| Austenitic Stainless Steel | 304/316 | Cr (18-20%), Ni (8-12%), Mo (316: 2-3%) | Excellent (especially 316) | Medium strength, high plasticity and toughness, non-magnetic | Solution treatment (cannot be hardened by quenching) |
| Martensitic Stainless Steel | 420/440C | Cr (12-18%), High C (0.2-1.0%) | Moderate (easy to rust) | High hardness and high wear resistance (quenchable and hardened) | Can be quenched & tempered |
| Ferritic Stainless Steel | 430 | Cr (10-30%), Low C (<0.1%) | Moderate | Low strength, moderate ductility, magnetic | Annealing (cannot be hardened by quenching) |
| Duplex Stainless Steel | 2205 | Cr (21-23%), Ni (4-7%), Mo (2-3%) | Exceptional | High strength (≈2× austenitic), good toughness | Solution treatment |
| Precipitation-Hardening Stainless Steel | 17-4PH | Cr (15-17%), Ni (3-5%), Cu/Nb additions | Good (better than martensitic) | Very high strength (can be age-hardened) | Solution + aging treatment |

The cost of stainless steel CNC machining parts depends on many factors: material(e.g., 304 or 316), part complexity (e.g., simple turning machining or complex milling machining ), tolerance requirements (critical tolerance such as ±0.005mm or simple tolerance), order quantity and surface finish specifications.
For an accurate quote, please send us your drawings and requests. We will provide a competitive price within 12 hours.
There isn’t only a type of stainless steel can meet all requirements. So it all depends on your industry requirement.
Normally we do polish, mirror polish, plating, sandblast, PVD and Passivation. If you have other special requirement about the surface finishing, welcome to talk with us.
We offer the quality guarantee before shipment. If stainless steel parts which you received is with problem, we will rework or remake them for free and bear the shipping costs.
