    The right alloy.
    The right specification.

    C-276 is a nickel-molybdenum-chromium alloy considered for demanding chemical-process environments. It is not universally resistant to every acid, concentration or mixed process stream.

    EMG reviews Hastelloy C-276 requirements through qualified supply partners. Include the drawing revision, quantity, material condition and required site date so sourcing and documentation can be defined before an order is placed.

    What to specify

    Hastelloy C-276

    UNS N10276

    Chemical process bolting · corrosion-exposed parts

    RFQ CHECK

    Define fluid composition, concentration, contaminants, product form and condition. Corrosion selection belongs to the responsible engineer.

    Reference designations are not stock, certified equivalence or guaranteed service suitability. Final product requirements govern every quotation.

    WHERE THE SPECIFICATION MATTERS

    Engineered around the application

    Mining and minerals processing plant

    Chemical processing and minerals treatment

    Specified bolts, nuts, valve components and sleeves where a plant material schedule calls for C-276.

    Socket head cap screws illustrating threaded-component applications

    Fastener assemblies

    Studs, hex bolts and companion nuts in Hastelloy C-276 to the approved drawing. Confirm thread form, length, mating material and any coating requirements.

    Precision-machined shafts, housings and threaded components illustrating component applications

    Parts to drawing

    Shafts, sleeves, collars and valve parts supplied through qualified manufacturing partners. Fits, surface finish, treatment and usable capacity are confirmed per enquiry.

    ENGINEERING CHECKPOINTS

    Control the details that matter.

    01

    The product specification governs

    Define fluid composition, concentration, contaminants, product form and condition. Corrosion selection belongs to the responsible engineer.

    02

    No automatic substitutions

    C-276 is not C-22 or Alloy 20. A generic Hastelloy description is insufficient for procurement and does not permit substitution.

    03

    Verify the finished part

    State the required chemical, mechanical, hardness and dimensional records. Request EN 10204 3.1 / 3.2, PMI or witness inspection where the project requires them; the quotation must identify the agreed scope.
