Alloy 450 Bolting Products
Alloy 450 is listed in the MONEL ALLOY material family. The reference data below should be checked against the governing product specification, product form and delivery condition before selection or certification.
The reference chemistry table for Alloy 450 lists Nickel (Ni): Balance / base metal; Copper (Cu): Grade specific; Iron (Fe): Grade specific; Manganese (Mn): Grade specific. Confirm exact limits and analysis tolerances against the governing standard and product form.
The mechanical-property table for Alloy 450 lists Tensile Strength: Grade / condition dependent MPa; Yield Strength: Grade / condition dependent MPa; Elongation: Grade / condition dependent %; Hardness: Grade / condition dependent HB / HRC. These are reference entries; supplied condition, dimensions, test method and governing specification control the requirements, and the figures are not design allowables.
No one-to-one Werkstoff number was verified for Alloy 450 in the cross-reference sources checked for this update. Confirm any proposed EN alternative against the governing specification.

Monel alloys are nickel-copper materials known for corrosion resistance, particularly in marine, chemical and selected reducing environments. Final selection should be based on the actual operating environment and the requirements of the applicable material standard.
Performance is grade-specific and can be tailored to oxidizing, reducing, chloride or chemical service conditions.
Selected grades retain useful mechanical or corrosion-resistant performance at elevated service temperatures.
Chemistry, heat treatment and mechanical requirements should be checked against the exact grade and product standard.
Material suitability depends on pressure, temperature, corrosion mechanism, fastener loading and fabrication condition.
Monel materials are selected for applications where the grade-specific combination of corrosion resistance, temperature capability and mechanical performance is appropriate.
Used for fasteners and components exposed to seawater and marine environments.
Selected grades are used in chemical processing where nickel-copper corrosion resistance is required.
Monel 400 is widely associated with resistance to hydrofluoric acid under suitable conditions.
Age-hardenable grades such as Monel K500 are used where higher strength is required.
Confirm the exact alloy designation, product form, heat treatment and intended service environment before specifying bolting.
Use grade-specific certified mechanical data for preload, torque, strength and temperature calculations.
Check compatibility with the actual process media, pressure, temperature and galvanic conditions for the intended installation.
No one-to-one Werkstoff number was verified for Alloy 450 in the cross-reference sources checked for this update, so this page does not assign a number. Confirm any proposed EN alternative against the applicable product standard and supplier certificate before substitution.
Suitability depends on the exact grade, product condition, temperature and required mechanical properties. Check the governing standard before use.
Monel grades are selected for demanding corrosion environments, but resistance varies significantly by grade and process chemistry.
Monel materials are used in specialized bolting, chemical processing, power, marine, aerospace and other engineering applications depending on grade.
Our engineering team can help you select suitable materials based on operating temperature, pressure and service conditions.
