The functioning of CNC machining is characterized by subtractive processes, wherein the feedstock
is machined to its final form by the removal of material. This process encompasses activities such
as drilling holes, boring lots and pathways, and shaping metal stock into new material with varying
tapers, diameters, and shapes.
Unlike additive manufacturing methods that involve the addition, layering, and deformation of
materials to achieve a specified shape, CNC machining achieves shapes through the removal of
material. This sets it apart from injection molding, where material is injected in a different state
of matter using a mold and formed to a predetermined shape.
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. What size of fillets are added when no specific fillet is specified by the 3D model
or drawing?
When no specific fillet radius is outlined in the 3D model or drawing, the machinist will incorporate
fillet radii at their discretion to optimize for easy machining.
In instances where a particular fillet radius is needed, explicit specification is encouraged.
As a rule of thumb, consider internal vertical edge radii exceeding 1/3 of the depth, while internal
horizontal edges may either remain sharp or be introduced with a radius ranging from 0.5mm to
1mm.
2. Quality Assurance
The trust our customers place in us is paramount. We adhere to proven quality management
principles to not only meet customer satisfaction but also to continually elevate our performance
and capabilities.
Our extensive experience spans decades, during which we have consistently met rigorous
regulations and remained PPAP compliant in industries like automotive, aerospace, and medical
devices. These industries set benchmarks for the quality assurance we uphold across all our
manufactured products.
3. What type of surface finishes does provide?
Our services encompass a wide array of finishing options to attain the desired appearance and
texture for your parts. We offer treatments for metal, texturing specifically for plastic injection
mold tools, and painting for both metal and plastic, among other choices. Discover more about
specifying your preferred surface texture in our blog.
4. How much import duty will I need to pay for my goods?
The import duty for your goods is not universally fixed, and its calculation depends on several
factors. In Australia, new CHAFTA regulations facilitate a phased introduction of duty-free imports.
Import duties vary widely and are contingent upon the nature of the imported goods.
Internationally, the majority of countries follow the Harmonized System (HS) codes, classifying
a broad spectrum of commercial trade goods.
