Indeed, stainless steel is known to be one of the more challenging metals for CNC machining.
Unlike many other materials, stainless steel actually becomes harder as it is machined,
rather than experiencing wear.
This, coupled with the significant heat generated during the machining process, can lead to
tool failure. Achieving the correct speeds, feeds, and utilizing appropriate tooling are critical
factors in successfully machining stainless steel.
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. Advantages of using Stainless steel
In addition to its shiny appearance, high corrosion resistance, stainless steel demonstrates
many characteristics that make it suitable for use in machining operations, such as:
1. Non-magnetic
2. Strength-to-weight advantage
3. Excellent fire and heat resistance
4. Excellent corrosion and impact resistance
5. Typically doesn’t require surface finishing
2. Challenges in Machining Stainless Steel
Indeed, stainless steel is known to be one of the more challenging metals for CNC machining.
Unlike many other materials, stainless steel actually becomes harder as it is machined,
rather than experiencing wear.
This, coupled with the significant heat generated during the machining process, can lead to
tool failure. Achieving the correct speeds, feeds, and utilizing appropriate tooling are critical
factors in successfully machining stainless steel.
3. Surface Finish for Stainless Steel
The finish of stainless steel can vary significantly depending on the surface roughness.
However, it is typically described as shinier compared to unfinished aluminum alloys,
and it tends to have a slightly darker and more silver color.
Stainless steel offers flexibility in achieving various surface finishes, including options such as
media blasting, sanding, hand-polishing, and powder coating. These processes can be employed
to achieve a wide range of surface finish textures and appearances.
