Other grades also in accordance with foreign standards or customer specifications by arrangement.<br />
IF steel; very good deep-drawing and stretch-forming<br />
ability in lower strength range; high r-and n-values;<br />
suitable for difficult deep-drawing components.<br />
A high component strength level can be achieved by<br />
the ability to meet accurate specifications in alloying<br />
technology.<br />
Good deep drawability through comparatively high<br />
r-value; suitable for deep-drawing components in<br />
intermediate strength range.<br />
Increase in strength only after forming and subsequent<br />
heat treatment (e.g. paint-baking); suitable for flat<br />
stretch-drawing components, which require high dent<br />
resistance. Both types of the H220BD and H260BD<br />
grades have isotropic properties.<br />
High strength level due to martensite islands in ferritic<br />
basis microstructure; good isotropic forming properties<br />
in upper strength range with favourable elasticity; high<br />
BH potential, high capacity for hardening and energy<br />
absorption; suitable for stretch-forming components<br />
(outer and inner) of auto body, above all for crash-relevant<br />
components.<br />
Very high strength level due to residual austenite in<br />
ferritic-bainitic basic microstructure which converts to<br />
martensite during forming; at the same time good<br />
isotropic properties; high capacity for energy absorption;<br />
high BH potential; suitable for inner supporting<br />
components having at the same time stretch-forming<br />
and deep-drawing properties.<br />
1) The values apply to the 0.2 % proof strength (Rp0.2 ), if the yield strength is not pronounced. If the yield strength is pronounced, they apply to the upper<br />
yield strength R . eL<br />
