-All food products
0H18N9 steel is used the deep turned elements in the industry devices
-Chemical and nitrogen: autoclaves, tubular heat exchangers, acid tanks, pipelines, etc.,
-devices in painting and pharmaceutical industries: autoclaves, distillation pots, mixers, transmission pipes
-Food and manufacturing for elements exposed to aggressive measures: salt, SO 2
-Carbon for the tube and the pumps are destined to work in the shaft acidic waters
