Hastelloy B3 Screws

Chem Plant sm

A high performace nickel alloy used for severe corrosion environments

Hastelloy B3 screws deliver the same excellent resistance to hydrochloric acid and other strongly reducing chemicals as other B-alloys (including B2) but with significantly enhanced thermal stability and improved ease of fabrication. In addition, B3 screws provide great resistance to knife-line and heat–affected zone attack. Like B2 alloy, B3 screws are not recommended for use in the presence of ferric or cupric salts which can cause rapid corrosion failure.

Availability: Hastelloy B3 screws are generally available in 1/2" sizes and larger due to materials availability. Most B3 screws are made to order.

Hastelloy BFastener & Flange Chemistry & Specifications

B3 alloy, UNS N10675, is specifically designed to deal with very aggressive hydrochloric acid (HCl), hyrdrobromic acid (HBr) and sulfuric acids (H2SO4) as well as acetic, formic and phosphoric acids. Additionally Hastelloy B3 has improved structural integrity over B2. However B3 has little chromium, and it should NOT be used with oxidizing media in the presence of salts.

Hastelloy C2000 Fasteners

Chem Plant sm

A high performace nickel alloy used for severe corrosion environments

Hastelloy C2000 fasteners combine the outstanding resistance to oxidizing media of C276 with superior resistance to non-oxidizing environments, making it a unique alloy for protecting chemical process equipment across a wide range of conditions including streams contaminated with ferric ions. It was designed to offer greater versatility compared to the other Hastelloy alloys. This was accomplished by increasing the chromium and molybdenum content in addition to adding a small, but effective addition of copper (1.6%). The addition of copper provides C2000 fasteners enhanced temperature capability in sulfuric acid, hydrofluoric acid, and dilute hydrochloric acid. Click here for information on the chemistry and specifications of these high performance nickel alloy fasteners.

Availability: Hastelloy C2000 fasteners are generally available in 1/2" sizes and larger due to materials availability. Most C2000 fasteners are made to order.

Corrosion Performance

Key Benefits

  • Excellent resistance to all acids (especially hydrochloric, sulfuric, and hydrofluoric) over large temperature ranges
  • Excellent protection from chlorides and other halide solutions, specifically pitting, crevice attack, and stress corrosion cracking
  • Excellent resistance to stress corrosion cracking and superior resistance to localized corrosion compared to C-276

Uses

  • Chemical process industry reactors, heat exchangers, columns, and piping
  • Pharmaceutical industry reactors and dryers
  • Flue gas desulfurization systems

 Hastelloy C2000 Fastener & Flange Grades & Chemistry

C2000 alloy, UNS N06200, is a corrosion resistant alloy with excellent resistance to uniform corrosion in oxidizing or re-ducing environments. Due to the addition of copper and the high content of chromium, it has enhanced corrosion resistance to sulfuric acid and process streams contaminated with ferric ions. In addition it has excellent resistance to stress corrosion cracking and superior resistance to localized corrosion as compared to C-276 alloy. This alloy has limited availability and can be made into  sizes only 1/2" and greater is size for fasteners.
