Stock sizes in music wire and stainless steel
Associated Spring Raymond Asia offers a broad variety
of helical compression springs in the SPEC selection. They
are reliable, inexpensive and efficient - the right combination
for general-purpose use throughout industry.
Material
 |
Music Wire - Per ASTM-A228
or AMS 5112. Music wire springs are not recommended for
applications where the temperature exceeds 121 deg. C
(250 deg F.) |
|
Stainless Steel Type 302
- ASTM-A313 or AMS 5688 spring tempered (chemical & physical
only). Stainless steel springs are not recommended for
applications where the temperature exceeds 260 deg. C
(500 deg. F). |
|
Type 302 stainless steel
is slightly magnetic. Surface of stainless steel may have
a residue of nickel on the surface. This is normal and
will not affect the function of the part. |
|
Wire diameter is prior
to forming |
|
Music wire will be furnished
unless stainless steel is specified. When inquiring or
ordering, use letter "M" or letter "S" as suffix to designate
music wire or stainless steel, respectively. |
|
No charge for certificate
of compliance when requested; certificate of chemical
analysis available, see price book. |
Direction of Helix - Right Hand
Ends
|
Squared and ground. Ends
to be square within 30 with axis O.D. size 0.057-0.088
in (1.45-2.24 mm) squared end not ground Free length L
is for reference use only. Load P is attained at length
L1. For stainless steel multiply P by 0.833. |
|
Load values shown are for
music wire |
|
For normal service, springs
should not be compressed below L1. (May take a set beyond
L1) |
|
To determine load P at
any length other than L1, multiply the proposed deflection
by the rate R. *[P = (L-Lx) x R]. When stainless steel
is used the value for rate R must be corrected by multiplying
R by 0.833. |
Finishes
Standard finish is that of the normal wire. Shot-peened and
plated finishes furnished on request. Allow sufficient additional
time for special finishes.
