Hastelloy C, Hastelloy C22 Brand: 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. Tapping Not recommended, machine threads, or roll-form them.


Same as high speed steel. Change to sharpened tools at regular intervals rather than out of necessity.

Evaporators, heat exchangers, filters and mixers used in sulfuric acid environments.

ASTM B Hastelloy C/C22 Round Bar · ASTM B N/N Bar

Hastelloy Alloy C B54 Bar is a nickel-chromium alloy bar that contains supplemental amounts of columbium, iron, molybdenum, aluminum, and titanium. Coolant-feed carbide tipped drills may be economical in some setups. Finish Boring C-2 or C-3 grade: Tension test shall be performed and shall comply to required mechanical properties for hot b74 cold finished, solution annealed rods such as tensile strength, yield strength, and elongation. Drilling C-2 grade not recommended, but tipped drills may be successful on rigid setup if no great depth.


Nitrogen gas can be substituted for hydrogen gases, but the cut quality will deteriorate slightly.


Hastelloy C22 Round Bar have high strength properties, heat treatable, good corrosion resistance, formability and weldability. Grind brazed tools as for finish turning and facing except back rake may be best at 0 degrees.

Use degree included angle on point. Dry, oil, or water-base coolant. High speed tools can be used, with lower production rates, and are often recommended for intermittent cuts.

Equipment for b5574 desulfurisation plants. Alloy C can be successfully fabricated by many methods. Dry2, oil3, or water-base coolant4. If feed slows and the tool dwells in the cut, work hardening occurs, tool life deteriorates and close tolerances are impossible.

Use positive axial and radial rake, 45 degree corner angle, 10 degree relief angle.

ASTM B574 Round Bar

Normal roughing Turning or Facing C-2 or C-3 grade: Hastelloy Alloy C22 Round Bar is a nickel-chromium alloy bar that contains supplemental amounts of columbium, iron, molybdenum, aluminum, and titanium. Hastelloy Round Bar is commonly used for valves, fasteners, tubing materials and mandrels.


Water-base coolant may cause chipping and rapid failure of carbide tools in interrupted cuts. Turning or Facing C-2 and C-3 grade: It has outstanding resistance to a wide variety of chemical process environments including ferric and cupric chlorides, hot 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.

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. Our alloys can be cut using any conventional plasma arc cutting system.

Equipment for processes utilizing halide or acid catalysts. Gun drill can be used. The molybdenum and high nickel contents in Hastelloy C Bars Alloy C makes the nickel steel alloy particularly resistant to pitting in plummeting atmospheres, whereas chromium suggests resistance to oxidizing media.

Components exposed to sour gas. Tipped reamers recommended, solid carbide reamers require vary good setup. Common uses of Hastelloy Alloy C22 include deployment in gas turbines, subservice safety valves, aircraft engines, thrust reversers, and industrial fasteners.
