347 pipe and spool drawings good mechanical properties
In most instances, the carbon content of the plate enables dual certification.
The cold work hardening rate of 347 stainless steel plate makes it less machinable than 410 stainless steel, but similar to 304. Type 347 stainless steel is a special type of austenitic stainless steel with excellent corrosion resistance. Type 347 stainless steel is stabilized with columbium, which allows it to avoid intergranular corrosion when heated to its sensitization temperature range. Type 347 is an austenitic stainless steel stabilized by the addition of niobium (plus tantalum) to reduce or prevent carbide precipitation during welding and when used at 800/1650?F (430/900?C).
