The following are key points which should be considered during machining operations:. Hardness Brinell kg, min. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. Monel K Round Bars is a nickel-chromium alloy bar that contains supplemental amounts of columbium, iron, molybdenum, aluminum, and titanium. ASTM B specification covers UNS N nickel-copper-aluminum alloy rounds, squares, hexagons, rectangles, and forgings and forging stocks manufactured by either hot working or cold working, and cold-worked wire.

Detailed machining parameters are presented Tables 16 and Hot-worked Cold-worked Multiple lengths 6 to 24 ft 1. Dry2, oil3, or water-base coolant4. Mill age-hardened products have been precipitation heat treated by the manufacturer and further thermal treatment is not normally required. Rough-turned or rough-ground Semi-smooth machined Smooth-? Monel K Round Bars is commonly used asmt valves, fasteners, tubing materials and mandrels. D Age hardening qstm treatment: Longitudinal strip 4 8.


Cold-worked wire shall not be out-of-round by more than one-half the total permissible variations in diameter shown in Table 7. After aging the material shall conform to the mechanical properties speci?

The maximum curvature depth of chord shall not exceed 8b65 value indicated multiplied by length in feet. Hot-worked material to be machined in longer b8865 should be speci?

B The allowances for hot-worked material in Table 5 are recommended for rods machined in lengths of 3 ft 0. Others may be added and should g865 equally suitable. The specimen shall be obtained from the actual material to be shipped or from a forged test coupon when applicable. Common uses of Monel K include deployment in gas turbines, subservice safety valves, aircraft engines, thrust reversers, and industrial fasteners.

MONEL K is a age-hardenable Nickel-Copper alloy which combines the corrosion resistance of Alloy with high strength corrosion fatigue and erosion resistance. Change to sharpened tools at regular intervals rather than out of necessity. Workmanship, Finish, and Appearance 8.

ASTM B865 – 04(2015)

For material in straightened and cut lengths, deduct 15 ksi MPa from above values. During aging, a slight permanent contraction takes place, but little warpage occurs because of the low temperatures and slow cooling rates involved. When a full cross section size test cannot be performed, the largest possible round specimen shown in Test Methods E 8 shall be used. Carbide-tipped tools are suggested for most applications.


In case of dissatisfaction with the results of the test, the manufacturer or supplier may make claim for a rehearing. B Not applicable to subsize tensile specimens less than 0.


C Hardness values are given for information only b8665 are not the basis for acceptance or rejection. Applications Propeller and pump shafts. B For cold-worked rods and bars under 1? Monel K is readily fabricated by standard commercial procedures.

ASTM B Round Bar is a precipitation-hardenable nickel-copper material that combines the excellent corrosion resistance characteristic of Monel with the added advantage of greater strength and hardness.

These amplified properties, strength satm hardness, are obtained by adding aluminum and titanium to the nickel-copper base and by a thermal processing used to effect precipitation, typically called age hardening or aging. Current edition approved Feb.

Heavy machining of this alloy is best accomplished when the material is in the annealed condition or hot-worked and quenched condition. MONEL K is a nickel-copper alloy, precipitation hardenable through additions of aluminum and titanium. N865, it can be further strengthened by cold working prior to precipitation hardening. Oil or water-base coolants will reduce thermal shock damage.

Applicable to material in coil.
