Inconel 601 fasteners are designed to withstand severe corrosion and high temperature exposure. These fasteners contain nickel and chromium alloys for excellent corrosion, heat and oxidation resistance. Nickel content retains ductility and high temperature strength after prolonged use. Fasteners of this grade produce a tightly adherent scale that resists spalling under severe thermal cycling conditions.

Inconel 625 Bolts were developed in the 1960s as a vapor-lined piping material to provide high strength even in extreme high temperatures ranging from freezing low temperatures to 1800¡ãF. Inconel 625 Bolts, also known as Alloy 625, are known for their amazing ability to maintain strength and heat resistance in and out of corrosive environments. The presence of nickel and chromium makes Inconel 625 bolts resistant to corrosion, oxidation and carburization. Molybdenum helps provide excellent fatigue strength and resistance to stress, pitting and crevice corrosion cracking even when exposed to chloride ions.

Inconel 625 bolts can be used in a variety of corrosive environments due to their ability to prevent stress corrosion, crevice corrosion and pitting corrosion. In mild applications such as atmospheric, fresh or salt water, neutral salts and alkaline media are almost completely tolerated. In more severe cases, nickel and chromium content provides resistance to oxidizing chemicals. Inconel 625 bolts are also resistant to non-oxidizing environments.

Inconel 625 Bolts are easy to weld using conventional welding processes, which is especially useful for Inconel 625 Weld Studs. This alloy is often chosen for its weldability compared to other highly alloyed nickel-based alloys. Alloy 625 resists intergranular corrosion even in the as-welded condition. Furthermore, post-weld heat treatment of the weld is not necessary to maintain corrosion resistance.

Stainless Steel Duplex SAF 2205 Hex Bolts are used in machinery and construction and can be used with nuts or threaded holes.

UNS S32205 Hex Bolts (also known as S31803) are made of high grade duplex 2205 stainless steel. Because this material is composed of at least 22% chromium, 6% nickel, and 3% molybdenum, it can withstand some of the harsh environmental conditions that other metals cannot, such as corrosion, cracking, erosion, pitting, and more. Stainless Duplex 2205 Hex Bolts also provide twice the mechanical strength compared to standard stainless steel.

Additionally, Duplex 2205 is the most widely used duplex grade on the market. Duplex 2205 alloy is a nitrogen-enhanced duplex stainless steel alloy. The effect of nitrogen is to significantly increase the corrosion resistance of the alloy; especially in the as-welded condition.

Hex head bolts are ideal for many types of industrial fastener applications. The six-sided design of the 2205 Hex Bolt allows the bolt to be tightened or loosened quickly and efficiently, improving overall work speed and quick turnaround. Some additional benefits associated with using UNS S32205 Hex Bolts (also known as S31803) include: Extremely strong, hot forged, ASTM A449 and SAE J429 specified, improved corrosion resistance.

Duplex 2205 bolts (EN 1.4462 ) are made of austenitic-ferritic stainless steel and are designed to provide higher strength and corrosion resistance than 300 series stainless steels. It helps users avoid stress corrosion cracking common to 316 and 317. Duplex 2205 bolts combine the stress corrosion cracking resistance and high strength of ferritic alloys with austenitic fabrication capabilities.

Duplex 2205 was tested under reverse bending stress at room temperature compared to SS316. The results show that Duplex 2205 has approximately twice the fatigue limit/yield strength.

Duplex 2205 bolts have a ductile to brittle transition at -50¡ãC and also become brittle at 300-1000¡ãC, so a temperature of -50¡ãC to 300¡ãC is recommended. Exposure to above 300¡ãC will not only cause embrittlement of 2205 bolts, but will also reduce corrosion resistance.

Offering the industry an improved stainless steel corrosion solution, Duplex 2205 Bolts have good sulfide corrosion resistance, as well as chloride pitting and crevice corrosion superior to 317L. The combination of chromium, molybdenum and nitrogen provides Duplex 2205 bolts with good chloride pitting and crevice corrosion protection, which makes them useful in marine environments, brackish water, bleaching operations, closed loop water systems and some food processing applications.
