ASTM A370-19 pdf free download. Mechanical Testing of Steel Products.The size of this pdf file is 19.4M.
ASTM A370-19 covers procedures and definitions for the mechanical testing of steels, stainless steels, and related alloys. The various mechanical tests herein described are used to determine properties required in the product specifications Variations in testing methods are to be avoided, and standard methods of testing are to be followed to obtain reproducible and comparable results. In those cases in which the testing requirements for certain products are unique or at variance with these general procedures,the product specification testing requirements shall control.
When this document is referenced in a metric product specification, the yield and tensile values may be determined ir inch-pound (ksi ) units then converted into SI (MPa) units. The elongation determined in inch-pound gauge lengths of 2 or 8 in. may be reported in ST unit gauge lengths of 50 or 200 mm, respectively, as applicable. The elongation determined in unit gauge lengths of 50 or 200 mm may be reported in inch-pound gauge lengths of 2 or 8 in., respectively, as applicable.
The specimen used to determine the original units must conform to the applicable tolerances of the original unit system given in the dimension table not that of the converted tolerance dimensions.
