4.Application: Austenitic stainless steels provide useful resistance to corrosion on a wide range of moderately oxidizing. Some austenitic stainless steel pipes are for general service, for sanitary installations, for water heater, for boilers, for superheaters, for heat exchangers and for condensators service.

5. key properties: These properties are specified for flat rolled product (plate, sheet and coil) in ASTM A240/A240M. Similar but not necessarily identical properties are specified for other products such as pipe and bar in their respective specifications.
