||Most widely used stainless steel spring material due to its excellent combination of physical properties and corrosion resistance.
||Similar to Type 302 except for the slightly lower carbon and higher nickel, which results in a more ductile, lower tensile alloy in the annealed condition. The major use of this alloy is in the annealed and 1/4 hard wire products such as cold heading wire, weaving, or screen wire, and lockwire.
||Molybdenum gives this material high creep strength at elevated temperatures and excellent corrosion resistance. (generally better then Types 302, 304, and 321.) Especially resistant to pit-type corrosion.
where welding is used in fabrication or where heat is
encountered as a service condition. Stabilized with
titanium to prevent sensitization. (Carbide precipitation
and intergranular corrosion.)
||Corrosion resistance comparable to Type 302 with physical properties comparable to music wire. Particularly useful where a compact, corrosion resistant spring is required. Considerably better than Type 302 for springs operating up to 600°F.
