Compare Stainless Steel Alloys
We offer a variety of stainless steel options to suit any
specifications or requirements. Stainless Steel 304 and
316 as well as Stainless Steel 304L and Type 360 (17-4) have all
proven to be high-quality options for CNC machining projects that
require either milling or turning.The metal has a very high tensile
strength, and has high resistance to corrosion and wear, resulting
in added product durability and part longevity.

CNC process service flow

Stainless steel alloy CNC machining has a wide range of
applications in many fields.
The following are some common stainless steel CNC machining
applications:
1.Manufacturing: Stainless steel alloy is widely used in the manufacturing
industry. Through CNC machining,
various stainless steel parts and components can be manufactured,
such as mechanical parts, connectors, fixtures,
bearing housings, etc. Stainless steel's corrosion resistance, high
strength and wear resistance make it a
commonly used material in manufacturing.
2.Medical devices: Stainless steel also has important applications in the manufacture
of medical devices.
Through CNC machining, surgical instruments, implantable
instruments, medical equipment enclosures
can be manufactured. Stainless steel's corrosion resistance, high
strength and biocompatibility make it ideal for
medical device manufacturing.
3.Automotive industry: The application of stainless steel in automotive manufacturing is
also gradually increasing.
Through CNC machining, auto parts can be manufactured, such as
exhaust pipes, intake pipes, body structural parts, etc.
Stainless steel's corrosion resistance, high strength and
lightweight properties make it an ideal material in the automotive
industry.
4.Aerospace industry: The application of stainless steel in the aerospace field has also
increased.
Through CNC machining, aerospace parts can be manufactured, such as
engine parts, structural parts and so on.
Stainless steel's high strength, corrosion resistance and high
temperature stability make it suitable for harsh environments
in the aerospace sector.
