With such processing, the dimensional cold rolled steel can have more accurate dimensional tolerances, better surface quality and improved mechanical properties as compared with hot-rolled coils.
Material Introduction
Name: DC07 for deep drawing
C 0.01
Mn 0.20
P 0.020
Ti 0.2
When there is no significant yield, RP0.2 should be used; otherwise ReL should be used. When the thickness is more than 0.50mm and not more than 0.70mm, the specified value of the yield strength is allowed to increase 20MPa; when the thickness is not more than 0.50mm, the specified value of the yield strength is allowed to increase 40MPa.
