|#302 Stainless Steel
||Most widely used stainless steel
spring material due to its excellent combination of
physical properties and corrosion resistance.
|#304 Stainless Steel
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.
|#316 Stainless Steel
||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
|#321 Stainless Steel
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.
corrosion and oxidation to 2150°F. Provides
springs with high resistance to corrosion and heat up to
750°F. Tough and ductile down to -310°F; is
nonmagnetic, easily fabricated and welded. Used for
structural parts, cathode ray tube spiders, thyratron
grids, sheathing, tube supports, spark plug electrodes.
||Age hardenable, nonmagnetic,
corrosion and oxidation resistant; high creep-rupture
strength 10 1300°F. Heavy cold working develops tensile
strengths of 290,000 psi. Stays tough and ductile to
-423°F. Resists chloride-ion stress-corrosion cracking.
For springs operating to 1200°F and tube structural
material is noted for its toughness over a considerable
range of temperatures, and has excellent resistance to
many corrosive environments. Monel 400 can be hardened
only by cold-working. It is useful at temperatures up to
and has very good mechanical properties at temperatures
below zero. Melting point is 2370-2460°F.
||Music spring wire is high carbon
steel of uniform chemical analysis. This wire is drawn
within rigid tensile, smoothness, and roundness
requirements and although very high in tensile strength,
must be capable of wrapping around itself without showing
signs of cracking or unevenness.
