Hastelloy Hexagon Bolt

Hastelloy Hexagon Bolt Description

Hastelloy is a nickel-based corrosion-resistant alloy, mainly divided into nickel-chromium alloy and nickel-chromium-molybdenum alloy. Hastelloy fasteners have good corrosion resistance and thermal stability, and are mostly used in the aviation industry and the chemical field.

Hastelloy fasteners include the following material grades:

HASTELLOY B-2 nickel-molybdenum alloy has excellent corrosion resistance in a reducing environment. The upgraded version of HASTELLOY B-3 B-2 has excellent corrosion resistance to any temperature and concentration of hydrochloric acid.

HASTELLOY C-4 has better thermal stability, 650-1040 degrees Celsius has better toughness and corrosion resistance.

HASTELLOY C-22 has better uniform corrosion resistance in oxidizing media than C-4 and C-276, and excellent local corrosion resistance. HASTELLOY C-276 has good resistance to oxidizing and moderately reducing corrosion, and excellent stress resistance Corrosion ability.

HASTELLOY C-2000 is the most comprehensive corrosion-resistant alloy with excellent resistance to uniform corrosion in both oxidizing and reducing environments.

HASTELLOY G-35 G-30 is an upgraded product with better corrosion resistance and thermal stability. HASTELLOY G-30 is a nickel-based alloy with high chromium content. It is excellent in phosphoric acid and other strong oxidizing mixed acid media.

HASTELLOY X combines high strength, anti-oxidation and easy processing characteristics.

Each of the above grades has a specific chemical composition, mechanical properties, and has its own strengths. It is not possible to generalize about the characteristics of hastelloy fastener.

Hastelloy C276 fastener

Hastelloy C276 is a very popular alloy for us for the reason that it is highly anticorrosive in a broad range of enveronments. STARWDH stocks an immense inventory of hastelloy c726 bolts and fasteners. Hastelloy C276 fasteners are made from a nickel-molybdenum-chromium wrought alloy that is an improved wrought version of alloy C. We are known for stocking hastelloy c276 bolts, nuts, screws, washers, studs, socket head cap screws, and many other fasteners for prompt shipment.

Hastelloy C276 fasteners and the rest of the hastelloy family has outstanding resistance to corrosion and to both oxidizing and reducing chemicals. Due to adaptability, hastelloy C-276 alloy can be applied in problem zones are more probable to occur in process zones. Hastelloy 276 fasteners (hastelloy c276 hex bolts,c276 bolts,hastelloy screws,hastelloy bolts,hastelloy nuts, hastelloy washer) are suitable for most chemical applications in the as-welded condition. However, it should be noted that in environments where attack of the C276 alloy weld joint is experienced, C22 weld filler materials should be considered.

What has made the alloy popular is that hastelloy C276 alloy has excellent resistance to a wide variety of chemical process environments, including strong oxidizers such as ferric and cupric chlorides, hot contaminated media (organic and inorganic), chlorine, formic and acetic acids, acetic anhydride, and seawater and brine solutions. It is often used in flue gas desulfurization systems because of its excellent resistance to sulfur compounds and chloride ions encountered in most scrubbers. C276 alloy has excellent resistance to pitting and to stress-corrosion cracking. It is also one of the few materials that with stands the corrosive effects of wet chlorine gas, hypochlorite, and chlorine dioxide. Hastelloy can be fabricated by a variety of Methods . HASTELLOY C276 alloy can be forged, hot-upset, and impact extruded. Although the alloy tends to work-harden, it can also be successfully deep-drawn, spun, press formed or punched.
