4、single unit is used, for example corrosion massgain in mg/dm2, the values stated in either inch-pound or SIunits are to be regarded separately as standard. The valuesstated in each system are not exact equivalents; therefore eachsystem must be used independently of the other. SI valuescannot be mixe

One such method is extrusion of billets withsubsequent cold working, by drawing, swaging, or rocking,wi
35、th intermediate anneals until the final dimensions arereached.5.4 Unless otherwise agreed upon between the manufacturerand purchaser, welded tubing shall be made from flat-rolledproducts by an automatic or semiautomatic welding processwith no addition of filler metal in the welding operation. Otherm
36、ethods of welding, such as the addition of filler metal or handwelding, may be employed if approved by the purchaser andtested by methods agreed upon between the manufacturer andthe purchaser. If filler wire is used, it must meet the chemicalrequirements of the appropriate grade as shown in Table 4.
37、Welded tube is normally cold reduced to the desired dimen-sions by such methods as drawing, swaging, or rocking. Themanufacturer must prevent contamination during welding byuse of proper precautions.6. Condition and Finish6.1 Metallurgical Condition:6.1.1 Grade R60001 product shall be in the recryst

The strength values listed above arefor alloys that contain oxygen concentrations in the range
45、900 to 1400 ppm. For alloys with other oxygen concentrations, the tensile properties are to be agreed uponbetween the manufacturer and the purchaser.BTo be agreed upon between the manufacturer and the purchaser.CThe tensile test is to be carried out at one or more of the temperatures listed in Table
46、 3 (or at another temperature) as agreed upon between the manufacturer andpurchaser. If one of the above temperatures is selected, the minimum properties shall be as listed for that temperature. If a different temperature is selected, the minimumproperties shall be agreed upon between the manufactur
47、er and purchaser.DParagraph 6.9.1 in Test Methods E8 allows small diameter tubes to be tested as full size tubular sections with snug-fitting metal plugs inserted into the ends of the tubeto permit proper gripping by the test machine jaws, as shown in Fig. 11 in Test Methods E8. Specimens for the te
48、sting of large diameter tubes are cut from the wall of thetube and are to satisfy the requirements of Figs. 12 and 13 in Test Methods E8.EThe properties in this table apply to tubes 0.125 in. (3.2 mm) outside diameter and larger, and 0.015 in. (0.38 mm) wall and thicker. Mechanical properties of tub
