Alloy 25 Bolting Products
Alloy 25 is listed in the S ALLOYS 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 25 lists Designation: Alloy 25; Material family: S Alloys; Composition limits: Use the applicable material/product specification and certified material test report. Confirm exact limits and analysis tolerances against the governing standard and product form.
The mechanical-property table for Alloy 25 lists Tensile Strength: Condition and product-form dependent; Yield / Proof Strength: Condition and product-form dependent; Elongation: Condition and product-form dependent; Hardness: Condition / heat-treatment dependent. 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 25 in the cross-reference sources checked for this update. Confirm any proposed EN alternative against the governing specification.

Alloy 25 combines the characteristics of its material family with grade-specific alloying and heat-treatment behavior suited to its intended service.
Microstructure and magnetic response depend on the exact alloy, processing route and condition; confirm these properties for the supplied grade.
Offers useful resistance to atmospheric and general industrial corrosion.
Selected grades can offer practical machinability for fabricated and machined parts.
Product form, processing and condition affect strength and dimensional stability; use certified data for the supplied material.
Alloy 25 is selected for engineered components and bolting where the material characteristics of this grade match the service environment.
Alloy 25 may be suitable when its certified grade and condition meet the application requirements; confirm against the governing material specification.
