CNC Milling 304 Stainless Steel Components – Flange

CNC milling 304 stainless steel components – flange provided by CNClathing.com – experienced CNC machining services China supplier with rich expertise. Stainless steel 304, also known as A2, is the most commonly stainless steel, it’s the austenitic stainless steel with a lower carbon composition, has excellent mechanical properties and good machinability, resistant to corrosive media and most environments, widely used in high-temperature environments and is versatile and to be used in a variety of fields. The 304 stainless steel CNC machined parts used for machinery are treated with the passivation process, passivation of stainless steel will make the parts more rust-resistant by removing free iron from the surface. Our CNC stainless steel milling services can provide not only flange machining but also various customized products as your design or drawings.

Is 304 Stainless Good for Machining?

Grade 304 stainless steel, while offering excellent corrosion resistance and good value, presents both advantages and challenges for machining operations. As the most common stainless steel globally, it provides good machinability but requires specific considerations during the machining process due to its work-hardening characteristics and low thermal conductivity. To achieve optimal results when machining 304 stainless, operators should maintain sharp cutting edges, make deep enough cuts to prevent work hardening, employ chip breakers for swarf management, and use abundant coolants and lubricants to manage heat concentration at cutting edges. While CNC machining has made working with 304 more precise and efficient, its high-strength properties still demand careful attention to proper machining techniques.
