Customized Stainless Steel Machining Parts High Precision CNC Turning Parts
Professional Factory CNC Service
Stainless steel stands as a favored alloy in various industries, including high-end precision
instruments, semiconductor manufacturing, and medical equipment production.
We specializes in manufacturing stainless steel parts known for their exceptional chemical
resistance, acid and alkali resistance, and corrosion resistance.
These parts find extensive applications in mechanical equipment, instrumentation measurement,
hydraulic control, and sensor equipment.
Our advanced turning and milling machines, along with surface treatment technology, empower
us to create stainless steel components with fine surface finishes and precise dimensions,
adhering to customer specifications.
In addition to corrosion resistance, stainless steel is weldable and is frequently employed in
vacuum components within highly corrosive gas and liquid processes, especially in semiconductor
applications.
Product Details
Stainless steel is highly resistant to corrosion and rust, making it suitable for situations
where a part may be exposed to the elements for a long period of time.
Stainless steel is also fairly malleable and ductile.
| Common Stainless Steel Materials | |
| No. | Properties |
| Stainless steel 304/304L | The most common alloy and is known for its pristine surface finish. It has significantly higher corrosion and oxidation resistance. Typically used in the manufacture of sensor parts, shafts, machinery parts, medical parts, and more. |
| Stainless steel 316/316L | It is slightly higher levels of chromium and nickel that exhibits improved heat tolerance, resistance to creep and pitting, and excellent tensile strength. Typically used in the manufacture of sensor, chemical & pharmaceutical equipment parts, and more. |
| Stainless steel 303 | It is a non-magnetic, austenitic stainless steel with good resistance to mildly corrosive atmospheres, but significantly less than 304. Typically used in the manufacture of screw, gears, fittings, bushings, shaft, and more. |
| Stainless steel 420 | It is a martensitic stainless steel with good corrosion resistance as well as strength and hardness. It is capable of being heat treated to a hardness of HRC 51 minimum. Typically used in the manufacture of pivots, cams, pump shafts, surgical instrument parts, valve components, and more. |
| Stainless steel 440C | It is a martensitic stainless steel, and is the highest carbon content from 400 stainless steel series. It is usually heat treated to reach hardness of 58 - 60 HRC. Typically used in the manufacture of valve seats, piston, shaft, and more. |
| Stainless steel 430 | It is a non-hardenable ferritic stainless steel with excellent finish quality. It has good corrosion resistance with good formability and ductility. Typically used in the manufacture of fittings, flanges fasteners, piston, and more. |
| Stainless steel 430FR | It is a free-machining solenoid quality alloy, ideal for parts that require corrosion resistance and high electrical resistivity. It has excellent corrosion resistance in fresh water, gaseous, moderately acidic, and low chlorine environments. |
| Stainless steel 630 | It is commonly referred to as 17-4 and is a precipitation-hardening martensitic stainless steel that offers superior corrosion resistance. It is magnetic, readily welded. Typically used in the manufacture of sensor housing, valve, pump shaft, and more. |

FAQ's
1. Varieties of Stainless Steel Available for CNC Machining
We provide a selection of 11 distinct stainless steel options for your CNC-machined parts,
including Stainless Steel 304, Stainless Steel 316, Stainless Steel 303, Stainless Steel 17-4PH,
Stainless Steel 416, Stainless Steel 2205 Duplex, Stainless Steel 420, Stainless Steel 440C,
Stainless Steel 430, Stainless Steel 301, and Stainless Steel 15-5.
2. How thin can you machine stainless steel?
CNC machining thin stainless steel components requires special attention.
The minimum thickness for metals should not go below 0.5mm. To optimize cost and machining
efficiency, it is advisable to increase the thickness of thin components to at least 0.8mm.
Thicker walls provide added stability and cost savings, except when weight is a critical consideration.
Thin features are more susceptible to vibration, which adds complexity and significantly extends
machining time.
3. How soon can I receive my parts?
We can produce quality parts in as little as two weeks if you provide us with complete 2D and 3D
CAD models. However, more complex parts with special features may have longer lead times.
Request a quote to receive more precise lead times based on your specific project.
Regarding shipping, our primary method is air freight, which typically takes a few days for delivery
from China to Europe or North America.
