What Is Stainless Steel?
Stainless steel plate is a flat rolled product that is 10 inches (254 mm) and over in width, 0.1875 inches (4.76 mm) and over in thickness. There are several grades of steel in which plate is available. Use the guide below to find out which is right for you.
| Grade | Description | Applications |
|---|---|---|
| 303 | Free machining, good mechanical and corrosion resistant properties | Mechanical and pharmaceutical components and parts |
