Hastelloy® fasteners & flanges are Available from SASA FLANGE – such as Hastelloy C276, which is generally considered a versatile and highly corrosion resistant alloy. Hastelloy slip on flanges have excellent corrosion resistance in both oxidizing and reducing media which makes it well suited for a variety of strong corrosive applications. Hastelloy slip on flanges also have exceptional resistance to both sulfuric acid and hydrochloric acid.
Because Hastelloy slip on flanges resist some of the most severe media, Hastelloy slip on flanges are often utilized in chemical processing applications where acid chlorides, solvents, formic and acetic acids, acetic anhydride, wet chlorine gas, hypochlorites, chlorine solutions and phosphoric acid are used. For chemical processing applications, Hastelloy C276 is the most common grade and one of the most corrosion resistant nickel alloys – exceeding that of most other nickel alloy grades like Inconel or Monel.

Frequently Asked Questions
Q: What is a hastelloy slip on flanges used for?
A: Slip-on flanges are used to connect corrosion-resistant piping to valves, pumps, and process equipment where easy alignment and fillet welding are preferred. Hastelloy grades such as C276, C22, and B3 are selected for aggressive chemical service, chlorides, acids, wet scrubbers, and high-temperature process lines. These flanges are machined to ASME B16.5 dimensions and supplied with EN 10204 3.1 certification, with optional X-ray inspection per ASME Section VIII UW-51.
Q: What materials are available for hastelloy slip on flanges?
A: Available materials include Hastelloy C276, B2, B3, C22, and Hastelloy X. These nickel alloy grades are supplied to ASTM B574 and ASME SB574 requirements, with related fittings and components covered by ASTM/ASME standards such as B366, B564, B462, and B626. Material conditions listed include cold drawn, hot finished, cold rolled, hot rolled, annealed, and mercury-free, depending on size, form, and customer specification.
Q: What pressure ratings does a hastelloy slip on flanges support?
A: Pressure ratings are produced according to the applicable ASME B16.5 flange class requested by the customer, since the exact class depends on size, alloy grade, temperature, and wall schedule.
