2.1 The basic state code is represented by an English capital letter.

2.2 The subdivision state code is represented by the basic state code followed by one or more Arabic numerals.

2.3 Basic state code

There are 5 basic states

Code Name Description and Application

F free machining state is suitable for products without special requirements for work hardening and heat treatment conditions during the molding process, and the mechanical properties of the products in this state are not specified.

O Annealed Condition For processed products that have been fully annealed for minimum strength.

H Work-hardened state Applies to products whose strength is increased by work-hardening, which may or may not undergo additional heat treatment to reduce strength after work-hardening.

W Solution heat treatment state Treatment state An unstable state, which is only applicable to alloys that are naturally aged at room temperature after solution heat treatment. This state code only indicates that the product is in the natural aging stage.

T heat treatment state (different from F, O, H state) is suitable for products that are stable after heat treatment (or without) work hardening. The T code must be followed by one or more Arabic numerals. The first digit after the T word indicates the basic type of heat treatment (from 1 to 10), and the subsequent digits indicate changes in the details of the heat treatment. Such as 6061-T 62; 5083-H 343 and so on.
