304 Stainless is a low carbon (0.08% max) version of basic 18-8 also known as 302.
Type 316 is more resistant to atmospheric and other mild environments than Type 304.
310S Stainless Steel has excellent resistance to oxidation under constant temperatures to 2000°F.
317L is a molybdenum bearing austenitic chromium nickel steel similar to type 316, except the alloy content in 317L is somewhat higher.
Alloy 321 (UNS S32100) is a titanium stabilized austenitic stainless steel with good general corrosion resistance.
Type 410 is a martensitic stainless steel which is magnetic, resists corrosion in mild environents and has fairly good ductility.
ASTM A213 ASME SA-213 TP347H Seamless Steel Tubes contains NB-Cr-Ni austenitic stainless steel.
Duplex 2205 (UNS S31803), or Avesta Sheffield 2205 is a ferritic-austenitic stainless steel.
Duplex 2507 (UNS S32750) is a super duplex stainless steel with 25% chromium, 4% molybdenum..
Material to UNS S32760 is described as a super duplex stainless steel with a microstructure of 50:50 austenite and ferrite.
ASTM A269 / A269M Standard Specification for Seamless and Welded Austenitic Stainless Steel Tubing for General Service
ASME SA 249 Standard Specification for Welded Austenitic Steel Boiler, Superheater, Heat-Exchanger, and Condenser Tubes.
904L stainless steel consists of chromium, nickel, molybdenum and copper contents, these elements give type 904L...
06Cr19Ni10 stainless steel is a grade of stainless steel produced in accordance with the American ASTM standard.
It refers to the state of final plastic deformation or final heat treatment of the delivered product. The hot-rolled or cold drawn (rolled) state or manufacturing state generally delivered without heat treatment; the heat-treated state after heat treatment delivery, or the normalizing, tempering, solid solution, annealing according to the type of heat treatment status.
|Cold-finished/hard (cold-finished as-drawn)||BK||No heat treatment after the last cold-forming process. The tubes therefore have only low deformability.|
|Cold-finished/soft (lightly cold-worked)||BKW||After the last heat treatment there is a light finishing pass (cold drawing) With proper subsequent processing, the tube can be cold-formed (e.g. bent, expanded) within certain limits.|
|Annealed||GBK||After the final cold-forming process the tubes are annealed in a controlled atmosphere or under vacuum.|
|Normalized||NBK||The tubes are annealed above the upper transformation point in a controlled atmosphere or under vacuum.|
