Alloy Types 
904L
Thunder Threads™ is known throughout the fastener world for its immense stock of fasteners in specialty alloys. Such is true for 904L, is a non-stabilized low carbon "high alloy” austenitic stainless steel. Copper is a primary component of this alloy which gives it greatly improved resistance to strong reducing acids, especially sulphuric acid. 904L is also highly resistant to corrosion caused by chlorides.
       
A-286

Thunder Threads Inconel inventory is very dynamic and vast.  We stock a wide variety of Inconel fasteners including Inconel A-286, which is used in high temperature, highly corrosive environments.  Contact Thunder Threads to check our stock regarding Inconel bolts, nuts, washers, studs, and socket products. 

AL6XN

AL-6XN alloy is a super-austenitic alloy that was developed to resist crevice corrosion, pitting, chloride-induced corrosion, and stress corrosion cracking. AL-6XN fastners can be made into custom parts including bolts, screws, nuts, washers, studs, and socket head cap screws because they are highly resistanct against alkaline and salt solutions.

Alloy 20 Fasteners

Alloy 20 is considered a nickel-chromium-molybdenum stainless steel alloy which has a wide variety of uses within the sulfuric acid industry. Alloy-20 fasteners are highly resistant to many other chemicals. Also known by many as Carpenter 20, these fasteners are desired by many engineers because they are resilient against pitting and chloride corrostion from sulfuric acid. Alloy20 fasteners are stock items for thunder threads in bolts, nuts, studs, washers, cap screws, and socket head cap screws

Alloy 50

Alloy 50, which is also known as Nitronic 50, is a special grade stainless steel that provides an excellent resistance to corrosion while not compromising in strength. If these characterics are important for your application, alloy 50 fasteners give you the most value. Thunder Threads™ offers Alloy 50 fasteners in a wide range of fasteners including bolts, nuts, washers, studs, screws, and socket head cap screws.

Alloy 60

Nitronic alloy 60 is a type of Austentic Stainless that has been Annealed and provides excellent corrosion resistance. Thunder Threads™ offers Nitronic 60 fasteners (also known as alloy 60 fasteners) in a wide variety of applications. In addition to custom "to print” fasteners, our stock include nitronic alloy 60 hex bolts, nuts, flat washers and stud bolts.

Avesta 2205

Avesta 2205 fasteners are available by Thunder Threads™. Avesta 2205 is a Duplex Stainless comprised of Ferritic & Austenitic properties that can be fabricated into many types of fasteners. Avesta 2205 has a better resistance to corrosion than 316 and is also very resistant to chloride cracking and stress coused from chloride.

Avesta 254 SMO

Avesta Sheffield 254 SMO®  also known by its UNS S31254 is an austenitic stainless steel that can be made into Avesta Sheffield 254 SMO fasteners.  This alloy is used in the fastener industry due to its excellent corrosion resistance to saltwater and acid halides. 

Carpenter 20

Carpenter 20 fasteners is a brand name of a material that is also referred to by many as Alloy 20.  This alloy is considered a nickel-chromium-molybdenum stainless steel that has a large number of applications throughout the acid manufacaturing world.  Carpenter 20 fasteners are highly resistent to pitting and corrosion and pitting caused by chlorides. 

Carpenter 21-12N

Carpenter 21 Fasteners which is an austenitic nitrogen, chrome-nickel alloy, that yields high strengths under high temperature and extreme environments.

Columbium

Columbium / Niobium is considered a valuable microalloying element for steel, sine it adds a substantial amount of strength to the resulting alloy. Once mixed with other alloys such as nickel , cobalt, and iron, columbium is considered a superalloy that is used in air systems including those developed by NASA.

Custom 450

Custom 450® Stainless, is a stainless steel alloy that is also known by its UNS S45000. Custom 450 fasteners were developed for their great resistance to corrosion while also being harder than your conventional 304 stainless steel fasteners.

Ferralium 255

Ferralium 255-SD50, Ferralium 255-SD40, and Ferralium 255-SD3AF fasteners are available in a wide variety of applications. Considered a "super duplex” by many, Alloy 255 fasteners have a long history of corrosion resistance in the oil & gas, paper, acid and industrial world.

Haynes Ultimet 1233

Considered a cobalt-chromium alloy, Haynes Ultimet 1233 offers excellent corrosion resistance when compared to the Hastelloy family of alloys. In addition Ulitmet fasteners have a very high tensile strength when compared to the duplex stainless steel fasteners familys. It is for this reason Haynes Ultimet fasteners are used in many blender, extruder, and valve applications.

Haynes™ 230
Haynes 230 fasteners are used in a wide variety of applications that require high tensile strength at high temperatures, while demanding excellent resistance to corrosion. Common applications can be found in gas turbine engines, heat treating baskets, and power plants.
 
Haynes™ HR-120

Haynes HR-120 fasteners are widely used in high temperature environments (ex. Incenerators, furnaces, radiators) due to its is a special ability to have a high tensile strength while at very high temperatures. Hayes HR-120 fasteners have a high nickel/chromium/iron content which when combined with tungsten allow it the inherent properties that make it popular in the industrial world.

Haynes™ HR-160Haynes HR-160 fasteners are made from a specialty alloy that is highly resistant to corrosion.  Contact Thunder Threads to learn more about Haynes HR-160 fasteners for our team of fastener professionals.
Inconel™ 25-6MO

Inconel 25 fasteners are made from UNS N08926 is a superaustentic stainless steel fastener alloy that highly resistant to corrosion environments found in the ssulfureic acid and phospfuric acid industry.

Nitronic Alloy 50

Nitronic 50 stainless steel fasteners is an excellent alloy for the petroleum, petrochemical, and chemical industry since it combines the strength and corrosion resistance which is not available in its price range.

Nitronic Alloy 60

nitronic 60 is an austentic alloy originaly engineered as a high temperature alloy. Nitronic 60 resists oxidation similar to 309 stainless steel, which is far superior to the conventional 304 stainless steel. Nitronic 60 has been acclaimed for its ability to resist galling.

Tantulum

Tantalum fasteners are manufactured from a plating process that involves the acid etching of the outer layer of a standard alloy fastener. The parts are then plated in a reactor by the element tantalum for the use in corrosive environment. This technique was originated for the use of less costly fasteners in environments that would typically require your higher cost high nickel alloy fasteners.

Titanium

Titanium is used heavily in the aerospace, auto, petrochemical, and prosthetic industry for its excellent resitance to corrosion. It is tough, very strong, durable, and has a low density, thus making it ideal in a wide variety of applications.
