| ASTM CODE | SPECIFITATIONS | APPLICATIONS |
| 304 | Base kind of stainless Steel. For Mechanical strength and oxidation up 400 °C. | Household goods, hollow-ware, catering equipment, food and process industry equipment, nitrogen and hyd rogen tanks, metal furniture, car parts and other vehicles, etc. |
| 304L | Same as 304 with low Carbon (better formability) | Thick-walled welded structures, strongly oxidizing envoirements as nitric acid, lining for coal hoppers, liquid fertilizer spray tanks, tomato paste storage tanks, etc. |
| 321 | Usefull in higher temperatures and with the content of titan higher corrosion resistance. | Thick-walled welded structures, strongly oxidizing envoirements as nitric acid, lining for coal hoppers, liquid fertilizer spray tanks, tomato paste storage tanks, etc. |
| 316 | For mechanical strenght and oxidation up to 600 °C. Excellent ductility, formability and toughness. Due to the content of Mo resistant to high oxidation and acid. | Textile-brewery-paper-medical and fatty acid industry, acet,c acid compounds, etc. |
| 316L | Same as 316 with low carbon but resistant up to 400 °C | Thick-walled welded structures in the same scope of application as 316. |
| 316 Ti | The version of 316, Ti alloyed, resistant to higher temperatures and oxidations. | Thick-walled elded structures in corroding environments, high temperature applications, developed for highly corrosive environments in the chemical and process industries and for sea water applications. |
