Inconel can be described as a chromium and nickel based superalloy, mainly used in high temperature applications. Inconel 600 bolts are also highly resistant to oxidation. It is important to note that the Inconel 600 device can operate at temperatures above 1000 degrees Celsius. Alloy 600 fasteners also offer outstanding properties such as resistance to carburization and chloride-rich environments. Alloy 600 hex nuts can also be used in environments with a high risk of corrosion. This means that Inconel 600 hex bolts and other fasteners made of a given material can be used in furnaces and chemical plants where there is a high risk of corrosion.

Hastelloy B2 fasteners are primarily used for excellent resistance to reducing environments such as hydrogen chloride gas, sulfuric acid, acetic acid and phosphoric acid. Like other Hastelloys, B2 fasteners can be used in the as-welded condition because they resist the formation of grain boundary carbide deposits in the weld heat-affected zone. Due to reduced ductility, B2 fasteners are not recommended for use between 1000¡ãF and 1600¡ãF.

ASTM A276 specification covers requirements such as chemical composition, mechanical properties, heat treatment and other supplementary requirements for 309 stainless steel round bars, square bars, hexagon bars and other extruded shapes.

Inconel 718 bolts provide corrosion resistance in reducing and neutral media, as well as in oxidizing atmospheres, provided that the oxidizing media allows a passive oxide film to form. Inconel 718 bolts have good mechanical properties and excellent resistance to corrosive environments.

ASTM A193 Grade B7M bolts and studs have the same chemical composition as Grade B7 (quenched and tempered medium carbon alloy steel) but have lower strength requirements requiring 100% hardness testing on all fasteners manufactured in the batch. Grade B7M bolts are resistant to chloride, sulfide and hydrogen stress corrosion cracking (SCC) and are often used in sour gas service.

Alloy 20 washers provide good performance in hot sulfuric acid, specifically they offer good resistance to stress-corrosion cracking in boiling sulfuric acid at specific range of 20% to 40% concentration, as well as general sulfuric acid resistance. Alloy 20 offers solid acid protection and will perform better than Duplex or even Monel, but for high temperature and high concentration acids, you may need to look to Inconel or Hastelloy fasteners. In addition, Alloy 20 washers also show useful resistance to phosphoric acid and nitric acid.
