H1 pure work hardening condition suitable for obtaining the desired strength by work hardening without additional heat treatment
H2 working hardening and incomplete annealing; Applicable to work hardening degree beyond the requirements of the finished product, after incomplete annealing, so that the strength of the specified index products.
State of H3 work hardening and stabilization; It is suitable for products with stable mechanical properties after work hardening after low-temperature heat treatment or due to the action of heat in the process of processing.
State of H4 work hardening and paint treatment; It is suitable for the products with incomplete annealing caused by paint treatment after work hardening.

Hxx4 use the corresponding hxx state plate, patterned plate with machining.
hxx5 to machine the state of hardened welded pipe.
h111 final annealing, then a small amount of work hardening (ratio
H11 has a light degree of hardening). This hardening is caused by operations such as stretching or straightening.
h112 hot work forming, then light work hardening, or light work hardening after a small amount of cold work, to meet the specific mechanical property requirements. A kind of
