    What metal are Valve Springs made of

    I'm doin a project in one of my computer design courses and we're doin a valvetrain assembly. We're trying to make the valve spring compress and i'm trying to assign the right material for the analysis.
    Does anyone know precisely what type of metal your average valvespring is made of? for some reason i'm having trouble finding out with even the internet... but i'll keep searching.
    Thanks

    I'm gonna guess stainless steel and see if it works..?

    1. A high-strength valve spring formed by subjecting an oil-tempered steel
    wire made from a steel material composition containing 0.5-0.8 wt % C,
    1.2-2.5 wt % Si, 0.4-0.8 wt % Mn, 0.7-1.0 wt % Cr, balance Fe and
    inevitable impurities, where, in the inevitable impurities, Al is no more
    than 0.005 wt % and Ti is no more than 0.005 wt %, and the largest
    non-metallic inclusion is 15 μm, to hardening treatment at a heating
    temperature between 950-1100 C. followed by cooling; tempering
    treatment followed by cooling; coiling; and nitriding, wherein the
    oil-tempered wire comprises 1-5 vol % residual austenite after hardening
    and tempering and the density of carbides larger than 0.05 μm in
    diameter is no more than 5 pieces/μm2 in the microscopic
    photograph of the oil-tempered wire.

    2. The high-strength valve spring according to claim 1, wherein the
    material steel further comprises one or more of: 0.05-0.15 wt % V,
    0.05-0.5 wt % Mo, 0.05-0.15 wt % W, and 0.05-0.15 wt % Nb.

    3. The high-strength valve spring according to claim 1, wherein the
    nitriding treatment is performed at a temperature no lower than
    480 C. to make the surface hardness no lower than 900 Hv.

    4. A method of manufacturing a high-strength valve spring, comprising:
    subjecting an oil-tempered steel wire made from a steel material
    composition containing 0.5-0.8 wt % C, 1.2-2.5 wt % Si, 0.4-0.8 wt % Mn,
    0.7-1.0 wt % Cr, balance Fe and inevitable impurities, where, in the
    inevitable impurities, Al is no more than 0.005 wt % and Ti is no more
    than 0.005 wt %, and the largest non-metallic inclusion is 15 μm, to
    hardening treatment at a heating temperature between 950-1100 C.
    followed by cooling; tempering treatment followed by cooling; coiling; and
    nitriding.

    5. The high-strength valve spring manufacturing method according to claim
    4, wherein the material steel further comprises one or more of: 0.05-0.15
    wt % V, 0.05-0.5 wt % Mo, 0.05-0.15 wt % W, and 0.05-0.15 wt % Nb.

    6. The high-strength valve spring manufacturing method according to claim
    4, wherein in the hardening heat treatment: the heating speed is no
    smaller than 150 C./sec; the heating temperature is no higher than
    1100 C. but no lower than the temperature T( C.)=500
    +750.multidot.C (Carbon %)+500.multidot.V (Vanadium %), or no lower than
    950 C., whichever higher; and the time period from the beginning
    of heating to the beginning of cooling by water or oil is no longer than
    15 sec.

    7. The high-strength valve spring manufacturing method according to claim
    4, wherein in the tempering heat treatment: the heating speed is no
    smaller than 150 C./sec; the heating temperature is
    450-600 C.; and the time period from the beginning of heating to
    the beginning of cooling by water or other coolant is no longer than 15
    sec.

    8. The high-strength valve spring manufacturing method according to claim
    4, wherein the nitriding treatment is performed at a temperature no lower
    than 480 C. to make the surface hardness no lower than 900 Hv.

    Thanks joshie i appreciate the effort, but i'm more looking for just an actual name of the metal, we arent getting into the elements and how they are formed into the springs and what not. I kept googling and found a lot of places saying titanium, but being that this project isn't as precise as an actualy valvetrain setup i don't want to make the springs out of titanium because i think itll just break instead of compress in the stress test. So i'm just gonna try and find a soft flexible metal and hope it works. Anyway thanks joshie

    titanium is the valve spring retainers. but its steel.. heat treated spring steel.

    thats all i found

    word... i know about the retainers cause i have titainium ones on my car but i guess like you i couldn't find a the exact name of the metal except steel, so i guess that's what it is, it's gonna just be a trial and error thing haha
    thanks for the help man

    springs are made of various metals combined.

    HD steel

    H11 steel

    hi tensile chrome silicone

    extra hi tensile chrome silicone
    vanadium

    these are just a few of the materials used to make springs.

    i talked with roger vinci at crane cams he said to write him an email and he'll help you out. rvinci@cranecams.com

    roger vinci forwarded me the email he sent mike.

They are both at the pinnacle in their respective positions.

    These are some of the current "simple" steel specs. on our LS Series springs:
    high tensile chrome silicone steel: good
    extra high tensile chrome silicone steel: better
    Pacaloy enhanced steel: better
    Pacaloy enhanced extra high tensile chrome silicone steel: best
