| Alloy | Characteristics |
|---|---|
| 303 | NOT FOR SHEET METAL. For use in automatic machining applications (screws). Corrosion resistant to atmospheric exposures, sterilizing solutions, most organic and many inorganic chemicals; most dyes, nitric acid and foods. |
| 304 | The most widely used of the stainless steel and heat resisting steels. Offers good corrosion resistance to many chemical corrodents as well as industrial atmospheres. Has very good formability and can be readily welded by all common methods. ASTM A240 Cold rolled, annealed and pickled. Finishes: 2B, #3, and #4. |
| 316 | Better corrosion and pitting resistance as well as higher strength at elevated temperatures than T304. Used for pumps, valves, textile and chemical equipment, pulp & paper and marine applications. ASTM A240 Cold rolled, annealed and pickled. Finishes 2B, #3, and #4. |
| 410 | Heat-treatable stainless used widely where corrosion resistance is not severe (air, fresh water, some chemicals). Frequently used in cutlery. This series is martensitic (magnetic). ASTM A240 Hot rolled, annealed and pickled. Finishes: Dull |
