TRIP / DUALPHASE steel grades

TRIP / DUALPHASE steel grades

TRIP / DUALPHASE steel grades

(OP)
I'm an austrian engineer who's looking for some NEW and ACTUAL information concerning dualphase and trip steel grades respectively.
I look for any information at this topics, as production parameters, usage in the automobile industrie, further
development in the future, easily said: ANY infos related
to this steel grades!

Thanks for help,

RE: TRIP / DUALPHASE steel grades

I saw a little tiny bit of Dual-phase steel sheet last year in the secondary industry. here's what I've got....


Chemistry:             Mechanical:
C:  0.1167             Yeild:   57.2ksi
Si: 0.247              UTS:    104.5ksi
Mn: 1.724              E-long:  20.64%
P:  0.019              N-Value:  0.162
S:  0.001              R-Value:  0.838
Cr: 0.338              Y.P.E.:   0.965%
Mo:<0.001              HRB:     90.0
Ni: 0.018              Width:    0.504"
Al: 0.397              Thick:    0.0770"
Cu: 0.004              Length:   2.000"
Nb: 0.009
Ti: 0.0062
V:  0.055
Sn: 0.006
B:  0.0001
Fe:97.417

The above are results from a good A2LA lab.

As far as I know the microstructure is a soft and tough ferrite w/ small martinsite "chunks" spread thorough it.
It's good steel that hardens well when hit w/ a stamping die. That allows for less material to be used and parts that are stronger and lighter. Part of the ultra light steel vehicle project I think.


Well thats what I know....
(or guess)
