2. 'O' annealing state is applicable to complete annealing to obtain the lowest strength of the processed product
3.'H' work hardening state is suitable for products whose strength is increased by work hardening. After work hardening, the product may undergo (or may not undergo) additional heat treatment to reduce the strength
4.'W' Treatment state An unstable state, only applicable to the solid solution heat treatment after the natural aging of the alloy at room temperature, the state code only indicates that the product is in the natural aging stage
5.'T’ heat treatment state (different from F, O, H state) is applicable to the product after heat treatment, after (or without) work hardening to achieve stability
