This 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. Dry, oil or water-base coolant. General plasma cutting recommendations are presented in Table Precipitation hardening is accomplished by holding the material at a high temperature, followed by furnace cooling and then air cooling.
Use standard positive rake tools on insert type bars. Mill age-hardened products have been precipitation heat treated by the sstm and further thermal treatment normally is aetm required. It is recommended that Monel K be annealed when it is welded and that any weldments be stress relieved prior to aging. In the event that 8b65 critical quality or more rigid inspection standards than those called out in this speci?
The following are key points which should be considered during machining operations:.

Please give us a Review. A superscript epsilon e indicates an editorial change since the last revision or reapproval. During machining these alloys work harden rapidly, generate high heat during cutting, weld to the cutting tool surface and offer high resistance to metal removal because of their high shear strengths.
Monel K Round Bars is commonly used for valves, fasteners, tubing materials and mandrels.
F Applicable to both hot-worked and cold-worked material. D Rounds over 41? C Applicable to 3 ft 0. Hot-worked Cold-worked Multiple lengths 6 to 24 ft 1. Heavy machining of this alloy is best accomplished when the material is in the asttm condition or zstm and quenched condition. The web must thinned to reduce thrust. Siddhagiri Metals and Tubes Rating: Detailed machining parameters are presented Tables 16 and Pumps and valves used in the manufacture of perchlorethylene, chlorinated plastics.
Bar, square bar, fasteners. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Our company has gained recognition globally for the excellence of our services and quality of the products we supply. If two decimals choices are possible, as when the digits dropped are exactly a 5 or a 5 f ollowed only by zeros, choose the one ending in an even digit, with zero de? This abstract is a brief summary of the b856 standard. Hardness Brinell kg, min. Bar and rod hot-? B86 K Round Bars has excellent cryogenic and heat ranges.
Originally approved in Characteristics Excellent mechanical properties from sub-zero temperatures up to about C. B Not applicable to subsize tensile specimens less than b8655. The maximum curvature depth of chord shall not exceed the value indicated multiplied by length in feet. Tapping Not recommended; machine threads, or roll-form them. Therefore, the recommended practice is to machine slightly oversize, age-harden, then finish to size. Siddhagiri Metals and Tubes Manufacturer: Plus, it can be further strengthened by cold working prior to precipitation hardening.
Rejection and Rehearing C A Dimensions apply to diameter of rounds, to distance between parallel surfaces of hexagons and squares, and separately to width and thickness of rectangles.

Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. Water-base coolant may cause chipping and rapid failure of carbide tools in interrupted cuts. Alloy K has approximately three times the yield strength and double the tensile strength when compared with alloy If brazed tool bar, grind 0 degree back rake, 10 degree pos. Rough-turned or rough-ground Semi-smooth machined Smooth-? 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.
The material should conform to the required mechanical properties in both aged and unaged conditions. Grind brazed tools as for finish turning and facing except back rake may be best at 0 degrees. Alloy K has approximately three 3 times the yield strength and double the tensile strength when compared with Mill age-hardened products have been precipitation heat treated by the manufacturer and further thermal treatment is not normally required. Workmanship, Finish, and Appearance 8.
Drilling C-2 grade not recommended, but tipped drills may be successful on rigid setup if no great depth. Number of Tests Turning or Facing C-2 and C-3 grade: Rough Boring C-2 or C-3 grade: Up to 4
