Extra deep drawing quality EDDQ: Vm < 15% Deep drawing quality DDQ: Vm 15 / 20% Drawing quality DQ: Vm > 20% However, for the stress-strain states from uniaxial tension to biaxial tension (stretching) are preferable to use IE and FLD.
For comparison, on the basis of limit drawing ratio there were determined conditions for quality deep drawings (CQ, DQ, DDQ, EDDQ) on volume fraction of martensite in structure and in the same similarly also for stretching capacity (CSQ, SQ, HSQ, ESQ).
