H04 Temper and Order Heat Treated. Tempers produced by controlled amounts of cold work of solution heat-treated precipitation hardenable or spinodal hardenable alloys. The old tempers designation according to NFA is defined as follows: Non tempering tempers Copper with beryllium: Subscribe to Premium Services Searches: The ranks 2 to 4 ast, to 3 figures showing the minimum value of the specified compulsory property except for D, G and M.

ASTM B601 – 18a

Tempers produced in the product by the primary manufacturing operations of casting and hot working and controlled by the methods employed in the operations. Between the work hardening condition “O” and the total work hardening one, there are three intermediate states. Tempers produced in the cold-worked precipiation heattreated or spinodal heat-treated alloys by thermal stress relief. For more general information about over specific copper, brass, and bronze alloy data sheets, choose one of the following links, or use one of our search techniques to reach specific products.

MatWeb is intended for personal, non-commercial use. Standard ASTM B defines the terminology in general use for indicating the temper of copper and copper alloy products. Part Two Medium Manganese Steels: The states obtained in this way are symbolized by the letter “H” followed by the figure 3 instead of the figure 1, and followed by the same figure that the one in the work hardening condition in which they were before that treatment. The solution treatment, heat treatment at high temperature, can be made in a furnace but for some alloys especially the alloys from the familyit can be made during a process of hot working.


Annealing followed by the quenching.

Hardening by strain hardening series, The products obtained by work hardening of which the state is symbolized by H1x, keep internal stresses during that deformation process, they are “fibrous”.

These states are so symbolized by the letter “H” followed by the figure 2 instead of the figure 1. The delivery states for the products having had an age hardening treatment are symbolized by the letter “T” followed by one or several figures depending if they are aged or artificial aged, simply quenched or strain hardened after quenching.

Cold Worked and Stress Relieved Tempers. H21, H22, H23… Stabilized conditions: As Hot Forged and Air Cooled. Or if you don’t have an account with us yet, then click here to register. As-drawing, without mechanical characteristics specifications.


By simply clicking the materials hot link, you can see a list of metal materials defined by the selected standard. In addition to heat treating astk attributes such as aging temperature, annealing temperature, and hot-working temperature, MatWeb has a complete list of mechanical and thermal properties and composition specifications for copper-base alloys.

Temper Designations for Cu and Cu Alloys — Wrought and Cast

Need more than one copy? Tempers produced by cold working the precipitation heat-treated or spinodal heat-treated alloys. This standard is also available to be included in Standards Subscriptions. Tempers produced in alloys that have been solution heat treated, cold worked and spinodal heat treated.

The age hardening consists of doing a serial heating and cooling to the product. Please contact us at webmaster matweb. Your Alert Profile lists the documents that will be monitored. It defines the terminology of the processes that produce the tempers and the observable changes in the axtm that result from the processes. With these treatments, the weld area has been transformed into a wrought structure, and the usual temper designations apply.
