Fasteners for Chemical Processing

Specialty materials battle the harshest acids and high temperatures

The chemical processing industry is renowned for its corrosion issues particularly from its use of strong acids and corrosive chemicals. No matter the industry: acid production, specialty chemicals, agricultural chemicals, fertilizers, or polymers specialty materials like nickel alloys, zirconium and tantalum as well as chemically resistant polymers are critical to a safe and reliable chemical infrastructure. If you unsure what is best, you could rely our decades of direct experience in the chemical processing industry for advice and guidance you could trust.

Corrosion Focus

• Hastelloy C276 is critical for resistance to acids like sulfuric and hydrochloric acid, while C22 is ideal for use in strong oxidizers like nitric acid-rich fertilizer production
• Monel bolts provide protection from hydrofluoric acid – which will even corrode Tantalum
• Tantalum and Zirconium are used in the most extreme corrosive conditions where boiling acids are common
• Engineered Polymers like PVDF and PEEK work in low temperature acidic environments.

High Temperature Focus

• Inconel fasteners are critical for their combination of high temperature, corrosion resistance
• Incoloy bolts are key for long-term continuous use in high temperatures where oxidation, carburization and creep resistance is needed.

Fasteners for Water Systems

Specialty metals provide water system protection far beyond rust

Simple exposure to water can cause rust, but salt water and water contaminated with chemicals can do far worse damage. Specialty material fasteners provide water treatment facilities, desalination plants and chlor alkali users the ability to deal with salt water, sulfuric acid, bleaching agents, chlorides and other chemicals.

Corrosion Focus
The Chlor Alkali Industry is tasked in purifying drinking water for every major city in the country. Dealing with bleach and chlorine solutions has it challenges but something we are very familiar with at Extreme Bolt.

Municipal Waste Water treatment facilities deal with a diversity of chemicals in order to produce clean water free of bacteria and other harmful agents. Chlor alkali, chlorines and even sulfuric acid are used in these corrosive processes.

Industrial Waste Water can have very challenging environments and is unique to each specific application ranging from specialty chemicals, mining operations or semiconductor processing. 

• Hastelloy bolts provide corrosion protection from sulfuric acid used in municipal water facilities as well as harsh chemically polluted waters produced by industry.
• AL6XN fasteners are key components to desalination. They provide resistance to salt water corrosion even up to 1000°F   
• Duplex 2507 bolts offer excellent resistance to pitting, erosion, crevice corrosion, corrosion fatigue and stress corrosion cracking in chloride environments.
• Titanium fasteners are an excellent choice for many Chlor Alkali applications dealing with bleach type solutions.

Fasteners for the Electronics Industry

Specialty metals and polymers make today's electronics possible

Electronics are in every facet of our life, from computers and cell phones to entertainment and wearable medical devices. They are no longer just an accessory but a critical component of society – and so are the specialty materials that make them possible. From high purity clean rooms to non-conductive polymers and corrosion resistant super alloys, specialty materials make our electronics possible.

Corrosion Focus
Like many other industries manufacturing is prone to corrosive environments. The electronics industry requires a multitude of strong acids such as hydrofluoric, sulfuric hydrochloric and piranha acid solutions for semiconductor etching, name a few. To deal with production as well as waste handling specialty materials are necessary.

• Monel bolts have the unique ability to resist hydrofluoric acid across most temperatures and concentrations – HF is key to manufacturing silicon components.
• Hastelloy C276 fasteners also play a role in semiconductor production for their resistance to sulfuric acid.
• Hastelloy C22 and Incoloy are used to prevent corrosion from strongly oxidizing nitric acid.

High Purity Focus
Another aspect of the semiconductor industry, is the need for high purity materials that will not off-gas or contaminate sensitive electronics. Often high purity engineered polymers are utilized in these environments they can achieve the desired levels of purity an be non-conductive as well.

• PEEK fasteners are extremely stable in hostile environments. This polymer will not react with most acids and is very temperature stable as well.

Non-Conductive & Electrical Focus

• Tantalum’s extremely high capacitance (ability to store electric charge) makes it critical for laptops, cell phones, and even medical devices.
• PEEK, PVDF and PTFE screws offer the electronics industry superior dielectric strength to insulate from electric fields.
• Ceramic fasteners made of Alumina and Zirconia also make excellent electronic insulators.

Downhole Oil & Gas Fasteners

High strength and corrosion resistance for exploration & drilling

From exploration to well stimulation and fracking, the downhole oil & gas sector is exposed to a combination of severe corrosion and strength issues which requires specialty materials fasteners such as Hastelloy, Inconel and MP35N. Extreme Bolt offers fasteners that are compliant to many critical oil & gas bolting and material standards including:

Please visit our Oil & Gas Standards page for more in-depth information on each of these quality specifications.

Corrosion Focus
Some of the harshest corrosion encountered occurs during fracking or acidizing where sulfuric (H2SO4), hydrochloric acid (HCl) or hydrofluoric acid (HF) is used to stimulate the well. Furthermore H2S, commonly known as sour gas, is a naturally occurring byproduct of oil drilling and exploration which is also creates highly corrosive byproducts. These corrosive conditions are further amplified by high operating pressures found in deep and ultra-deep wells.

Since oil and natural gas is also found in porous rocks and shale in saltwater environments, chloride corrosion can also be an issue. Geothermal wells also contain brines which are made up of corrosive chlorides, siliceous compounds and gases, such as carbon dioxide, and Sulphur.

• Hastelloy bolts service the most severe hydrochloric and sulfuric acid fracking
• Incoloy 825 bolts provide excellent resistance to sour gas environments
• Duplex 2507 and AL6XN fasteners service moderately corrosive situations involving salt water and brines

High Strength Focus
In addition to corrosion, the downhole industry also requires extremely high strength bolts for a variety of applications. To deal with these extreme conditions some of our most specialized materials are deployed:

• Titanium Grade 5 (6AL-4V) offers a great combination of high strength, light weight and corrosion resistance (148 KSI, typical UTS)
• Incoloy 925 bolts offer high strength in sour gas conditions (165 KSI, typical UTS)
• Inconel 718 is used in situations that demand the strongest alloys, look to age-hardened and corrosion resistant (210 KSI, typical UTS)
• MP35N is the highest strength material we offer with an ultimate tensile strength of over 225 – 290 KSI. This material is not only very strong but also quite corrosion resistant as well.
