Typical % Composition
Summary |
"Cr 18, Ni 8.0 -
10.5, C .04 - .10" |
|
Applications |
"Used primarily
when material is subjected to extreme
temperatures. The high carbon helps
retain strength at the elevated
temperatures." |
|
Corrosion Resistance |
"Austenitic Cr -
Ni stainless. Better corrosion resistance
than 302. Essentially non-magnetic,
becomes slightly magnetic when cold
worked. Lower carbon content means
less carbide precipitation in the
heat-effected zone during welding
and a lower susceptibility to intergranular
corrosion." |
