What Are Duplex Steel UNS S31803 Nuts?
Duplex steel UNS S31803 nuts are a type of nut made from duplex stainless steels. These steels are composed of two distinct phases: a ferrite phase and an austenite phase which gives those excellent mechanical properties as well as superior corrosion resistance. The combination of high strength and corrosion resistance makes these nuts suitable for a wide range of applications in industries such as marine, oil & gas, chemical processing, food & beverage processing, construction, mining and more.

Duplex steel UNS S31803 Nuts have many uses across various industries. They can be used in marine applications such as shipbuilding or offshore platforms because they are highly resistant to seawater corrosion. They can also be used in oil & gas applications due to their strong mechanical properties and ability to resist chloride-induced stress corrosion cracking (SCC). Additionally, Duplex Steel UNS S31803 Nuts can be used in chemical processing plants or food & beverage processing lines due to their good corrosion resistance in acidic environments. Finally, they can be used in construction or mining applications due to their high strength and abrasion resistance. We offer various kinds of products like Duplex steel UNS S31803 Washers, Duplex Steel UNS S32205 Nuts, etc.

DUPLEX STEEL S31803 LOCK NUTS
Duplex steel UNS S32205 is an alloy with excellent mechanical properties including high strength levels along with good ductility and toughness even at cryogenic temperatures down to -50°C (-60°F). It also offers good wear resistance along with excellent corrosion resistance which makes it ideal for use in corrosive environments such as seawater or acidic solutions like hydrochloric acid or sulfuric acid solutions at temperatures up to 300°C (570°F). The combination of these properties make it suitable for use in many industrial applications requiring reliable service life under harsh conditions such as those found offshore or near coastal areas.
Types of Duplex Steel UNS S31803 Nuts
There are several different types of duplex steel UNS S31803 Nuts available on the market today including hex nuts, jam/ lock nuts, heavy pattern hex thin nuts (HTN), heavy hex flange lock nuts (HFLN) and more. Depending on your application requirements you may need one type over another so it’s important to make sure you select the right one for the work. For example, if you need a nut with excellent vibration resistance then an HTN would be best suited for your needs while if you need a nut that won’t loosen easily then a jam/ lock nut would be the right fit for you.
