Description |
Hastelloy C-22 is a versatile nickel-chromium-molybdenum alloy with better overall corrosion resistance than other Ni-Cr-Mo alloys available today, including hastelloy C-276, C-4, and A625. Alloy C-22 has outstanding resistance to pitting, crevice corrosion and stress-corrosion cracking. It has excellent resistance to oxidizing aqueous media including acids with oxidizing agents, wet chlorine and mixtures containing nitric acid or oxidizing acids with chlorine ions. Hastelloy C-22 has outstanding resistance to both reducing and oxidizing media, and because of its versatility can be used where "upset" conditions are likely to occur or in multipurpose plants.
Workability |
Hastelloy C-22 can be fabricated using the same techniques as are used for alloys C-276 or C-4. It can be welded, forged, hot-upset and impact extruded. Alloy C-22 can also be successfully deep-drawn, spun, press formed or punched, although the alloy tends to work-harden.
Parts which have been hot formed or severely cold formed should be heat treated at 2050 °F and rapid quenched prior to final fabrication or installation.
Application |
Some of the area of present or potential use for Hastelloy C-22 are: Acetic acid/Acetic Anhydride, cellophane manufacturing, chlorine spargers, chlorination systems, circuit board etching equipment, complex acid/chemical mixtures, fans and blowers, galvanizing line equipment, gas scrubber systems, geothermal wells, HF furnaces, incineration systems, nuclear fuel reprocessing, pesticide production, phosphoric acid applications, pickling system components, plate heat exchangers, selective leaching systems, sulfur oxide cooling towers, sulfonation systems, and tubular heat exchangers.
1 Q: What's the payment term?
A: T/T 30% for down payment, Then T/T balance on the actual weight of ready for shipment products on the basis of the Seller's account.
2 Q: How to ensure your products is qualified?
A: The Quantity and weight of product are certified by the seller’s Inspection Certificate and the quality is certified by the Mill Taste Certificate agreed form.
3 Q: How to confirm the Acceptance of Goods and Quality Control?
A: Once the manufacturing of a batch is complete, two samples will be acquired at random by the buyer’s representatives for testing at independent labs. One sample will be sent to a lab in Seller’s country and the other sample to a lab in buyer’s country.
