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.
