See Guide G101 formethods of estimating the atmospheric corrosion resistance oflow alloy steels.5.3 Application of heats of steel to which bismuth,selenium, tellurium, or lead has been intentionally adde

11、d shallnot be permitted. Compliance with this requirement shall bebased on a statement on the steel certificate indicating thatthese elements were not intentionally added.5.4 Product analysis made on finished rivets representingeach lot shall conform to the product analysis requirementsspecified in

16、 about the axis of the rivet, and the hardness shall betaken as the arithmetic average of the three measurements.7. Dimensions7.1 Dimensions of rivets, unless otherwise specified, shallconform to those of one of the head types provided in ASMEB 18.1.2.8. Number of Tests and Retests8.1 Hardness:8.1.1

17、 The requirements of this specification shall be met incontinuous mass production for stock, and the manufacturershall make sample inspections to ensure that the productconforms to the specified hardness requirements. Additionaltests of individual shipments of material are not ordinarilycontemplated

18、. Individual heats of steel are not necessarilyidentified in the finished product.8.1.2 Additional hardness tests of individual shipments ofrivets are not ordinarily required. When required, Supplemen-tary Requirement S1 shall be specified.8.2 Head Bursts and Duds:8.2.1 From each lot, the number of

19、tests and the acceptance/rejection criteria for cracks (bursts) and duds shall be inaccordance with Practice F1470 using the sampling levelcharacteristic specified for Surface Discontinuities.9. Specimen Preparation9.1 Rivets used for testing shall be heat treated in thefollowing manner prior to tes

20、ting:9.1.1 Grade 1Normalize by air cooling from above thetransformation range.9.1.2 Grade 2Anneal by heating to 1450F (790C),holding for 30 min at temperature and cooling in the furnace.9.1.3 Grade 3Normalizing test samples shall be at theoption of the manufacturer.9.2 If any test specimen shows def

21、ective preparation, it shallbe discarded and another specimen substituted.10. Visual Inspection for Head Bursts and Duds10.1 The rivets shall be inspected for cracks (bursts) andduds. Sampling and inspection shall be in accordance with 8.2.Rivets having an opening at the periphery of the head widert

22、han 0.020 inch plus 0.05 times the rivet diameter shall beconsidered nonconforming (see Note 1).NOTE 1Crack and burst are two names for the same thing. Eachdesignates an abrupt interruption of the periphery of a rivet head byseparation of the metal. Such interruptions do not adversely affectstructur

23、al strength, corrosion resistance, or other functional requirementsof the rivet, but are unsightly if they are large.11. Test Methods11.1 Hardness tests shall be conducted in accordance withTest Methods F606/F606M.11.2 Chemical analyses shall be conducted in accordancewith Test Methods A751.12. Insp
