Stainless Steel 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.

Product Major Applications Availability
Grade: UNS S30815
Composition:
21Cr-11Ni-67Fe-N-SI-Ce

A grade very similar to 309 stainless steel but with alloying element additions that enhance the metals creep strength and resistance to oxidation particularly in cyclical conditions

Grade:
UNS S17400
W Nr. 1.4542
Composition:
78Fe-17Cr-4Ni-4Cu-Cb

A precipitation (age hardenable) stainless steel offering high strength and hardness, good corrosion resistance and fabricating characteristics.

Grade:
UNS S31254
W Nr. 1.4547
Composition:
55Fe-20Cr-18Ni-6.1Mo-0.5Cu-N

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.
