N/A Nickel & cobalt base corrosion, temperature and wear-resistant alloys are classified as moderate to difficult when machining, however, it should be emphasized that these alloys can be machined using conventional production methods at satisfactory rates. 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. The following are key points which should be considered during machining operations

N/A Hastelloy® Alloy B-2 does work harden, but can be formed when the proper precautions are taken. Sheet (0.063" thick) in the heat treated condition at 1950 ºF and rapid quenched has an average olsen cup depth of 0.57" or 14.5 mm.

N/A Hastelloy® Alloy B-2 resists the formation of grain boundary carbide precipitates in the weld heat-affected zone, making it suitable for most chemical process applications in the as-welded condition. The heat-affected weld zones have reduced precipitation of carbides and other phases to ensure uniform corrosion resistance.

N/A Make sure tools are sharp at all times. Change to sharpened tools at regular intervals rather than out of necessity. A 0.015 inch wear land is considered a dull tool.

N/A Use positive rake angle tools for most machining operations. Negative rake angle tools can be considered for intermittent cuts and heavy stock removal. Carbide-tipped tools are suggested for most applications. High speed tools can be used, with lower production rates, and are often recommended for intermittent cuts.

N/A Use heavy, constant, feeds to maintain positive cutting action. If feed slows and the tool dwells in the cut, work hardening occurs, tool life deteriorates and close tolerances are impossible.

N/A Superior resistance to hydrochloric acid, aluminum chloride catalysts and other strongly reducing chemicals. Excellent high-temperature strength in inert and vacuum atmospheres.

Hastelloy® Alloy B-2 is a nickel-molybdenum alloy particularly suited for equipment handling reducing chemical environments.

Applications in the chemical process industry involving sulfuric, phosphoric, hydrochloric and acetic acid. Temperature uses vary from ambient temperature to 1500 ºF depending on the environments.
