Description
304/304L Stainless Steel is dual certified stainless steel tubing is a very low carbon "18-8" austenitic chromium-nickel stainless
steel with good corrosion resistance and superior resistance to
inter-granular corrosion following welding or stress relieving. The
low carbon percentage limits the formation of harmful carbides to
such an extent that this grade may be safely used for most
operations of welded construction, and where the service
temperature is limited to 800° F
It is non-magnetic in the annealed condition and not hardenable by
heat treatment. Both hardness and tensile strength can be increased by cold working, which may cause slight
magnetism. The dual certified 304/304L meets specifications for
both 304 and 304L stainless steel, and may be interchanged and used
safely for either grades application. 304/304L stainless steel is
available in rounds, squares, rectangles, structural angle shapes,
round and rectangular welded tube, and schedule pipe. 304 sheet and
plate can be cut into shapes or rings on Speedy Metals High
Definition Plasma cutter.
304/304L Stainless Steel Pipe Mchineability and Weldability
Machinability is rated at 45% of B1112. Average cutting speed 75
ft/min. Easily welded by all commercial processes except forge or
hammer welding. The resultant weld has good toughness and
ductility. Annealing is recommended after forging to maintain
maximum corrosion resistance. 304/304L can be forged between
2100°-2350° F. Do not forge below 1700° F
304/304L Stainless Steel Tubing Heat Treating
304/304L is not hardenable by heat treatment. Cold working
increases tensile strength and hardness. Annealing range is between
1850° and 2050°F. Cool rapidly. Water should be used for heavier
sections; air for lighter sections. The stress relieving range is
between 400° and 750°F.
