304, 304L Stainless Bar and Structural
| Product Description |
| Type 304 is the basic "18-8" chromium-nickel stainless steel. It combines excellent mechanical properties with remarkable resistance to many corrosive agents encountered in domestic and industrial use. It is useful where sanitation and cleanliness are important. It is non-magnetic in the annealed condition and not hardenable by heat treatment. Both hardness and tensile strength can be increased by cold working. This is an electric-furnace product manufactured to meet the exacting standards of the aircraft industry. Bars are available not only in the regular 304 analysis, but also in an extra-low-carbon analysis, known as Type 304L. The advantage of this analysis is that it precludes any harmful precipitation in the 800° F - 1500° F range, such as might otherwise occur in welding heavier sections. |

| Specifications |
| ASTM A276, ASTM A479, AMS 5639, QQ-S-763 |
| |
| Weldability |
| Excellent. L-Grade reduces intergranular corrosion at weld site Annealing after welding helps maintain maximum corrosion resistance. |
| |
| Corrosion Resistance |
| Maximum corrosion resistance in annealed condition shows good resistance to strong oxidizing acids, such as nitric acid, and resists attack by a wide variety of organic and inorganic chemicals. Intergranular corrosion may occur if heated within or cooled through the range of 800° F - 1500° F. |
