TISCO top quality 347/347H stainless steel hot rolled plate, 347/347H cold rolled stainless steel sheet
347 is frequently used for the fabrication of equipment, which must be placed in service under severe corrosive conditions, and is also common to the petroleum refining industries. that consistently used 347 include:
▪ High temperature chemical processes
▪ Heat exchanger tubes
▪ High temperature steam service
▪ High pressure steam pipes
▪ Radiant superheaters
▪ Boiler tubes
▪ Heavy duty exhaust systems
▪ General refinery piping

Alloy 347 stainless steel plate can be easily welded and processed by standard shop fabrication practices.
The alloy is quite ductile and forms easily.
The high sulfur content of Alloy 303 also has a detrimental impact on hot workability. If hot forming is required, once again, 304 should be considered as an alternate selection.
The cold work hardening rate of 347 stainless steel plate makes it less machinable than 410 stainless steel, but similar to 304.
