The process of stainless steel fabrication begins with choosing the right method. This will vary with the geometry of the part, the type of usage it will get and what it is made of. Here are examples of some choices for different metal fabrication processes:
1. Cutting: This is the most fundamental process in metal fabrication, and it can be accomplished through waterjet and laser cutting, chopping, sawing, shearing, and chiseling. Cutting is what turns the sheet metal into a piece of the required size and shape. Today, waterjet and laser cutting comprise the foremost technologies available.
2. Casting: A die forms a mold, and the fabricator pours molten metal into it. This metal cools down and turns solid, and the part remains after removing the die.
3. Forging: High-pressure machinery compresses raw metal, allowing a fabricator to bend and shape it.
4. Punching: Turrets punch pre-designed patterns into the metal, either for decorative purposes or utility.
5. Drawing: This process uses tensile force to pull liquid metal into a tapered die.
6. Milling: A milling mechanism bores perforations into the metal, which, due to the nature of the machine, can be non-circular.
7. Drilling: A drill cuts holes into the metal using a circular bit.
8. Turning: The piece of metal goes onto a spinning platform, allowing a technician to cut it radially with a tool as it spins.
Extrusion: A ram forces billets through a die. This extrusion process forms cylindrical parts, such as pipes or electrical wires.

After the initial process turns out the resulting part, it is possible a secondary finishing process may be required. This may be some sort of assembly if two or more parts need to be joined. The part may also need deburring, grinding, riveting, adhesive application, bolting or painting.
