STAINLESS STEEL
Main characteristics of stainless steels.
| FEATURES AND APPLICATIONS OF AISI 303 |
| Cr-Ni austenitic steel, not hardenable, non-magnetic in the annealed condition; slightly magnetic when cold worked; Excellent workability and seizure resistance due to the addition of sulfur; particularly suitable for processing on automatic machines and therefore with chip removal (eg.: shafts, bushings, bolts, nuts, etc.). Not suitable to high corrosion conditions. |
| FEATURES AND APPLICATIONS OF AISI 304 |
| Cr-Ni steel with a low content of C, austenitic, not hardenable, corrosion-resistant, non-magnetic in the annealed condition, slightly magnetic when cold worked. Good weldability and good resistance to intergranular corrosion; used for general purposes. (eg: home applications, decorative and architectural elements, food industry, kitchen utensils, general use etc.) |
| FEATURES AND APPLICATIONS OF AISI 304L |
| Cr-Ni steel with a very low content of C, austenitic, not hardenable, particularly suitable for welded constructions, it has excellent resistance to intergranular corrosion. |
| FEATURES AND APPLICATIONS OF AISI 310 AND AISI 309 |
| Cr-Ni austenitic refractory steel, not hardenable, well resistant to high temperatures. It may be employed normally up to 1100 ° C (eg.: installations for thermal treatments, furnace exchangers, particular for ovens, etc.). |
| FEATURES AND APPLICATIONS OF AISI 316 |
| Cr-Ni-Mo austenitic steel, not hardenable, non-magnetic. The presence of Mo gives a good resistance to corrosion (eg.: chemical equipment in particularly severe conditions, equipment in contact with water or marine atmosphere, etc.). |
| FEATURES AND APPLICATIONS OF AISI 316L |
| Cr-Ni-Mo steel with a low content of C., austenitic, not hardenable, non-magnetic, especially suitable for welded constructions; it has excellent resistance to intergranular corrosion. |
| FEATURES AND APPLICATIONS OF AISI 321 |
| Cr-Ni steel stabilized with Ti, austenitic, not hardenable, particularly suitable for welded constructions and uses between 400 ° C and 800 ° C. Insensitive to intergranular corrosion (eg.: rings for collectors of aircraft, parts of reactors, welded constructions, equipment for the chemical industry, etc.). |
| FEATURES AND APPLICATIONS OF AISI 420 |
| Martensitic stainless steel with Cr, hardenable; magnetic, maximum corrosion resistance in hardened and polished status (eg.: surgical instruments, knives, etc.). |
| FEATURES AND APPLICATIONS OF AISI 430 |
| Ferritic stainless steel to Cr, not hardenable, magnetic and easily workable. Resistant to atmospheric agents and alkaline solutions of organic acids. It resists to oxidation up to 750-800 °C. (eg: decorative architectural elements, parts for oil burners, equipment for bars restaurants, housewares, automobile accessories, screws, etc.). |
| FEATURES AND APPLICATIONS OF AISI 430F |
| Ferritic stainless steel to Cr, not hardenable, magnetic. Best workability and seizure resistance due to the addition of sulfur, particularly suitable for machining on automatic machines with high speed. |
