It is in the form of hot-worked and cold-worked. A low corrosion rate in rapidly flowing seawater combined with excellent resistance to stress-corrosion cracking in most freshwaters, and its resistance to a variety of corrosive conditions led to its wide use in marine applications and other non-oxidizing chloride solutions. In the annealed condition UNS N Round Bars is an alloy that is easy to form and fabricate with no requirements for additional heat treatments to re-balance the alloy. Monel Round Bars is a nickel-chromium alloy bar that contains supplemental amounts of columbium, iron, molybdenum, aluminum, and titanium.

Specimens shall be free from sharp bends or kinks. The distance between the jaws of the testing machine, with the specimen in place ready for testing, shall be not less than 10 in. Holes are to be drilled to midsection and the bottom of the hole shall be parallel to the entrant surface.
Recalibration shall be performed at least once per 8 h shift. Wire shall be excluded from these requirements. Shapes other than those listed below shall be tested to the extent set forth in the approved procedure. The scanning path shall be circumferential or helical with the beam directed along a radius of the rod.

Preparation for Delivery S Intended generally for machining where an over-hauled surface is desired, essentially for machined step down shafts or parts machined in short lengths of 3 ft mm or less. Material is selected from heats of known, good hot malleability. In such cases, the user should run pilot forging tests to ensure himself that such material has the desired hot malleability range. No mechanical properties are offered since material is to be subsequently hot worked.
Intended primarily for hot heated bolts but is of somewhat inferior quality, as to surface seams and cracks compared to forging quality, see X1. Provides for better surface inspection than does hot-worked material and often employed where welding is involved where removal of mill oxide is desired. NOTE X1. Material is thermally treated to relieve the major portion of the internal stresses resulting from cold-working and may have a very thin light to medium oxide. Annealed for softness and with a dull matte?
