This standard is issued under the fixed designation F; the number 1 This test method is under the jurisdiction of ASTM Committee F07 on. ASTM F describes sustained load testing (SLT) of high strength steels to evaluate the possibility of hydrogen embrittlement. G2MT Labs is proud to offer cutting edge hydrogen embrittlement testing that satisfies the requirements of ASTM F, F, and F

Work Item s – proposed revisions of this standard. The relative susceptibility of different materials to hydrogen embrittlement may be determined in accordance with Test Method F and Test Method F This combination of alloy and heat treat level has been used for many years and a large database has been accumulated asfm the aerospace industry on its specific response to exposure to a wide variety of maintenance chemicals, or electroplated coatings, or both.
Components with ultimate strengths higher than — ksi may not be represented by the baseline. In such cases, the cognizant engineering authority shall determine the need for manufacturing specimens from the specific material and heat treat condition of the component.
Green Specialty Service Inc. Products
Deviations from the baseline shall be reported as required by section The sensitivity to hydrogen embrittlement shall be demonstrated for each lot of specimens as specified in section 9.
The first part gives general information concerning requirements for hydrogen embrittlement testing.
The second is composed of annexes that give specific requirements for the various loading and specimen configurations covered by this test method see section 9. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. A If the hardness requirements of any of the sampled specimens are ast, satisfied, only those specimens of the lot that are individually inspected for conformance to these requirements shall be used for testing.
B The sole source of manufacture of Colcad known to 5f19 committee at this time is Columbia Chemical in Brunswick, Ohio, www.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. C After baking, the specimens shall be dipped into any appropriate chromate conversion coating solution for minimum time that will produce an adherent and continuous coating as described in AMS-QQ-P Type II.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Tensile strength of each specimen must be within 10 ksi of the average.
Round the average of three readings per specimen per Ast, E NFS of each specimen must be within 10 ksi of the average. The change in diameter at fracture load for each specimen must be within 0. Range Optimum Cadmium as CdO 2. Meet tolerances of corresponding drawings.
