Mechanical Properties and Other Requirements 6. It has excellent resistance to pitting and stress corrosion cracking. Originally approved in Rejection and Rehearing It is informational only and not an official part of the standard; the zstm text of the standard itself must be referred to for its use and application. 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.

Where rods are ordered in multiple lengths, a 1? Gun drill can be used.

Not recommendedbut C-2 grades may be successful on good setups. Product and chemical analyses shall be performed on the materials and shall conform to the required chemical composition in molybdenum, chromium, iron, tungsten, cobalt, carbon, silicon, manganese, vanadium, phosphorus, sulfur, titanium, nickel, aluminum, copper, and tantalum.

Dry, oil or water-base coolant. The markings shall have no deleterious effect on the material or its performance and shall be sufficiently stable to withstand normal handling.


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. Hastelloy Bar has excellent cryogenic and heat ranges. The values given in parentheses are for information only. Hastelloy C22 Round Bar have high strength properties, heat treatable, good corrosion resistance, formability and weldability. Workmanship, Finish, and Appearance 8.

Oil or water-base coolant. For each multiple, an allowance of 1? Equipment for flue-gas desulfurisation plants. Use degree included angle on point. Dry, oil, or water-base coolant.

Nitrogen gas can be substituted for hydrogen gases, but the cut quality will deteriorate slightly. Last previous edition approved in as B — Siddhagiri Metals and Tubes Manufacturer: Use positive axial and radial rake, 45 degree corner angle, 10 degree relief angle.

Molybdenum is the most important alloying constituent in Hastelloy B2 Bars Alloy B2 that offers note-worthy corrosion resistance to plummeting atmospheres. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Request quote on this grade. Current edition approved June 1, Reaming C-2 or C-3 grade: C-2 or C-3 grade: Carbide-tipped tools are suggested for most applications.

The web must thinned to reduce thrust. Tension test shall be performed and shall comply to required mechanical properties for hot or cold finished, solution annealed rods such as tensile strength, yield strength, and elongation.

Bar, hex bar, square bar, wire spool, wire cuts, loose coil, sheet, plate, coiltube, pipe, nipple, elbow, fitting, coupling, flange, fasteners, forging, disk, machined. It is the responsibility of the user of this standard to become familiar with all hazards including those identi? Finish Boring C-2 or C-3 grade: A superscript epsilon e indicates an editorial change since the last revision or reapproval.



Water-base coolant may cause chipping and rapid failure of carbide tools in interrupted cuts. Organic chloride process equipment. A water-base astk mist may also be effective.

Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Siddhagiri Metals and Tubes Rating: End Milling Not recommendedbut C-2 grades may be successful on good ast. Dimensions and Permissible Variations 7. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.

asm Change to sharpened tools at regular intervals rather than out of necessity. 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.

A number in parentheses indicates the year of last reapproval. Historical Version s – view previous versions of standard.

Tool geometry same as high speed steel.
