The HXXX status codes are as follows:
a) H111
It is suitable for products that have undergone an appropriate amount of work hardening after final annealing, but the degree of work hardening is not as good as that of H11 state.
b) H112
Suitable for hot forming products. The mechanical properties of the product in this state have specified requirements.
c) H116
It is suitable for products made of 5XXX series alloys with magnesium content ≥ 4.0%. These products have specified mechanical and exfoliation corrosion resistance requirements.
d) Status code of checker plate
The state code of the checkered plate and its corresponding state code before embossing are shown in Table 4:
