This g196 corrected to the proper 10 aztm 25 incl. The following three alloys are included:. The hardness requirements shall be as prescribed in Table 2 for solution heat treated or solution heat treated and cold worked and in Table 4 after prescribed heat treatment.
NOTE 1—Mechanical property data determined on other than round cross sections, for sizes under 0. One is to be tested in the as-sampled condition, and one in the precipitation heat-treated condition. The values stated in each system may not be exact equivalents; therefore, each astk shall be used independently of the other.
Now offering hollows upon request. These products meet property requirements in Table 3 and normally require no further heat treatment by the user. These special combinations of properties such as increased ductility, electrical conductivity, dimensional accuracy, endurance life, and resistance to elastic drift and hysteresis in springs, may be obtained by special precipitation-hardening heat treatments.
