2205 Bolts

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.

Stainless Steel Duplex SAF 2205 Hex Bolts are used in machinery and construction and can be used with nuts or threaded holes. Since they can be tightened with a wrench, fully threaded hex bolts are specially designed to work more efficiently. Additionally, 2205 hex bolts are stronger than standard stainless steel, meaning they can be used for jobs that require high workloads and good corrosion resistance.

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.
