Overview

As a leading supplier & manufacturer in China, AEETHER supply cost-effective Hastelloy C-22HS Products.

HASTELLOY® C-22HS® alloy is the premier nickel-chromium-molybdenum, corrosion-resistant material for oil and gas industry use. Cold working of the alloy at levels between 30 and 65% result in high room temperature yield strengths. It exhibits exceptional resistance to sour gas environments and is NACE/ISO approved.

C-22HS® alloy is available in the form of plate, sheet, strip, billet, bar, wire, pipe, and tube. Round products in the form of solid bars are available up to 10" with various amounts of cold work to achieve high strength and toughness by simultaneously retaining the excellent corrosion resistance of the alloy.

The data in this document is believed to be useful for applications in the oil & gas industry, or other industries which may require an alloy with excellent corrosion resistance and strength levels higher than “standard” HASTELLOY® C-22HS® alloy.

Early testing of C-22HS® alloy was focused on material in the annealed + age-hardened condition where the material was annealed at 1975°F (1079°C) and age-hardened at 1300°F (704°C)/16h/Furnace cool (FC) to 1125°F (607°C)/32h/Air-cool (AC.) In this “standard condition” C-22HS® alloy will typically have strengths around 100 ksi (690 MPa). While this strength level is almost double of “C-type” alloys in the annealed condition, many oil and gas applications require even greater strength.
