Stainless Steel Alloys

Iron Based Alloys:

We offer a range of stainless steels (iron based alloys) which have:
a resistance to corrosion superior to that of the more common austenitic grades; superior resistance to high temperature corrosion; or a combination of corrosion resistance and strength.

17-4PH
UNS S17400
W Nr. 1.4542
A precipitation (age hardenable) stainless steel offering high strength and hardness, good corrosion resistance and fabricating characteristics.Selected items from local stock; balance imported; ex-stock or mill availability78Fe-17Cr-4Ni-4Cu-Cb
blue.gif254SMO
UNS S31254
W Nr. 1.4547
A high alloy austenitic stainless steel having greater resistance to pitting and crevice corrosion than ALLOY 904L. Thus a useful alloy for more demanding seawater, desalination, bleach plant and chemical plant applications. Also flue gas cleaning.Selected items from local stock; balance imported; ex-stock or mill availability55Fe-20Cr-18Ni-6.1Mo-0.5Cu-N

ALLOY 904-6% Mo
UNS N08925
W Nr. 1.4529
The higher molybdenum content than ALLOY 904L gives increased resistance to pitting and crevice corrosion in acidic environments. Used in seawater, pulp and paper industry, and pollution control systems.Imported; ex-stock or mill availability47.5Fe-20Cr-25Ni-6Mo-1.5Cu

ALLOY 904L
UNS N08904
W Nr. 1.4539
An austenitic stainless steel having good resistance to general corrosion, pitting and crevice corrosion in acidic environments. Used in seawater, pulp and paper industry, and pollution control systems.Comprehensive range of plate, bar and pipe from local stock; also imports from stock & mill production.49Fe-20Cr-25Ni-4.5Mo-1.5Cu
 red.gifGRADE 309
UNS S30900
W Nr. 1.4828
Another stainless steel for use at high temperatures but with lower nickel than GRADE 310 enabling the alloy to be more resistant to sulphidation.Imported; ex-stock or mill availability 64Fe-23Cr-13Ni
red.gifGRADE 310
UNS S31000
W Nr. 1.4841
A high temperature stainless steel having useful strength and oxidation resistance. GRADE 310S is a controlled carbon variant while GRADE 314 has a higher silicon content and hence slightly better oxidation resistance.Selected items from local stock; balance imported; ex-stock or mill availability55Fe-25Cr-20Ni
