This alloy is resistant to the formation of grain boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process applications in an as welded condition. Alloy C has exceptional resistance to a wide variety of chemical environments.

Other industry applications are pulp and paper digesters and bleach areasscrubbers and ducting for flue gas desulfurization, pharmaceutical and food processing equipment. It has outstanding resistance to a wide variety of chemical process environments including ferric and cupric chlorides, b54 contaminated mineral acids, solvents, chlorine and chlorine contaminated both organic and inorganicdry chlorine, formic and acetic acids, acetic anhydride, sea water and brine solutions and hypochlorite and chlorine dioxide solutions.

Alloy C also resists formation of grain boundary precipitates in the weld heat affected zone making it useful for most chemical processes in the as-welded condition. It has excellent resistance to pitting and stress corrosion cracking.

Alloy C can be successfully fabricated by many methods. The alloy tends to work harden but with the proper care, the alloy is readily hot and cold formed.

Complete information on welding, machining and forming is available. During machining these alloys work harden rapidly, b74 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:. Change to sharpened tools at regular intervals rather than out of necessity.

Negative rake angle tools can be considered for intermittent cuts and heavy stock removal. Asm tools are suggested for most applications.

High speed tools can be used, with lower production rates, and b754 often recommended for intermittent cuts. If feed slows and the tool dwells in the cut, work hardening occurs, tool life deteriorates and close tolerances are impossible. Detailed machining parameters are presented Tables 16 and General astj cutting recommendations are presented asm Table A water-base coolant mist may also be asrm.

A viscosity at degrees F from 50 to SSU.

Dilute with water to make Water-base coolant may cause chipping and rapid failure of carbide tools in interrupted cuts. A viscosity at degree F from 50 to SSU.

HASTELLOY C is not prone to grain boundary precipitation in the as welded condition and therefore suitable for many chemical process applications Applications Digesters and bleach plants in the paper industry. Components exposed to sour gas. Equipment for flue-gas desulfurisation plants. Evaporators, heat exchangers, filters and mixers used in sulfuric acid environments. Organic chloride process equipment. Equipment for processes utilizing halide or acid catalysts.

Dry, oil or water-base coolant. Finish Boring C-2 or C-3 grade: Use standard positive rake tools on insert type bars. Grind brazed tools as for finish turning and facing except back rake may be best at 0 degrees. Use positive axial and radial rake, 45 degree corner angle, 10 degree relief angle.


Oil or waterbase coolants will reduce thermal shock damage of carbide cutter teeth. End Milling Not recommendedbut C-2 grades aatm be successful on good setups.

Same as high speed steel. Oil or water-base coolants will reduce thermal shock damage. Drilling C-2 grade not recommended, but tipped drills may be successful on rigid setup if no great depth. The web must thinned to reduce thrust.

Use degree included angle on point. Gun drill can be used. Oil or water-base coolant. Coolant-feed carbide tipped drills may be economical in some setups. Reaming C-2 or C-3 grade: Tipped reamers asstm, solid carbide reamers require vary good setup. Tool geometry same as high speed steel. Tapping Not recommended, machine threads, or roll-form them. Others b5574 be added and should be equally suitable. Table 18 Plasma Arc Cutting Our alloys can be cut using any conventional plasma arc cutting system.

The best arc quality is achieved using a mixture of argon and hydrogen gases. Nitrogen gas can be substituted for hydrogen gases, but the cut quality will deteriorate slightly. Shop air or any oxygen bearing gases should be avoided when plasma cutting these alloys.
