Site by Infinity Arts. The following three alloys are included:. Precipitation Heat Treatment 9. The material for manufacture shall be cast and worked to such purity and soundness as to be suitable for processing by hot working, cold working, and annealing to produce a uniform wrought structure and specified temper in the finished product. Modulus of Elasticity Tension.
Alloys are used in a wide range of applications requiring very high strength and stiffness with good conductivity. Workmanship, Finish and Appearance If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
These products meet property requirements in Table 3 and normally require no further heat treatment by the user. Historical Version s – view previous awtm of standard. C The upper limits in the tensile strength column are for design guidance only.
