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. Now offering hollows upon request. One is to be tested in the as-sampled condition, and one in the precipitation heat-treated condition. Number of Tests and Retests The tensile strength requirements shall be prescribed in Table 2 and Table 3 after precipitation heat treatment in accordance with 8.

We specialize in beryllium bar, but offer an additional selection of beryllium copper bar in a variety of additional specifications and offer cut to length programs from our strategically located facilities around the world. The following section was renumbered. Distributors will offer small quantity buys while mills will generally only sell large quantities, with delivery times anywhere from 10 to 50 weeks depending on adtm and form required This material is stocked primarily in Bar Products by 5 distributors but is also available to a lesser extent in Wire Products, and Flat Rolled Products.

Further thermal treatments of these tempers are not normally required. The following three alloys are included: Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. Workmanship, Finish and Appearance Dimensions and Permissible Variations Alloys are used in a wide range of applications requiring very high v196 and stiffness with good conductivity.
