SS 309 : With a relatively high chromium content of 25%, this alloy provides good oxidation resistance up to 1700°F(927°C). Due to instability of the scale formed on this alloy under some conditions, its primary value is in applications where the environment is destructive to high nickel alloys. In these applications where sulphur, lead or zinc may be present, it is particularly useful by virtue of its high chromium content and low nickel content. It also is subject to carbide precipitation in the 800°F(426°C) to 1500°F(816°C) range and a low carbon or stabilized alloy should be used where the environment is 1500°F range and a low carbon or stabilized alloy should be used where the environment is corrosive
Double Balanced Weave
Consists of a series of alternating double left-hand and right-hand spirals joined together by a straight or crimped cross-rod.
Most commonly used in elevated temperature applications for Sintering, Brazing and Annealing. .
