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
wow i really appreciate that mrr23
no problem
yeah i just sent out the email i'll let you know what happens, and thanks for the reccomendations for metals.
-Mike
roger vinci forwarded me the email he sent mike.

He's a pretty knowledgeable guy on that stuff.
I appreciate it again.
Over my head guys but nice to know for future conversations. Glad you found out what you need to know Unsubscribed :)
