The values shown represent the general opinion and are intended for information to enable the designer to better understand the forging characteristics of these various alloys. Alternatively, samples may be taken from separately forged test bars of the same heat as the forgings in the lot provided the wall thickness and amount of working for the test g283 are equivalent to those for the forgings.
Work Item s – proposed revisions of g283 standard. NOTE 3—Due to the discontinuous nature of the processing of castings into wrought products, it is not always practical to identify speci?
