AISI 304H Bolting Products
AISI 304H is listed in the AUSTENITIC STAINLESS STEEL 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 AISI 304H lists Chromium (Cr): Primary corrosion-resistant alloying element; Nickel (Ni): Austenite stabilizer; Carbon (C): Controlled to suit grade and condition. Confirm exact limits and analysis tolerances against the governing standard and product form.
The mechanical-property table for AISI 304H lists Tensile Strength: Condition and product-form dependent —; Yield Strength: Condition and product-form dependent —; Elongation: Condition and product-form dependent %; Hardness: Grade and condition dependent —. These are reference entries; supplied condition, dimensions, test method and governing specification control the requirements, and the figures are not design allowables.
Werkstoff / EN cross-reference for AISI 304H: 1.4948. This comparison does not guarantee interchangeability; confirm chemistry, product form and condition against the governing specification.

AISI 304H is the higher-carbon 304-family variant intended for applications where elevated-temperature strength is important. Key performance features vary by grade and condition.
AISI 304H is selected when higher carbon is important in service.
The grade provides elevated-temperature capability, subject to product form and specification.
This characteristic supports use of AISI 304H in appropriate industrial environments.
Performance depends on the certified material condition and governing specification.
AISI 304H is selected for bolting and engineered components where its corrosion, temperature or fabrication characteristics match the service environment.
Typical applications include general fabrication. Confirm suitability against the project specification, temperature, media and product condition.
Typical applications include food and process equipment. Confirm suitability against the project specification, temperature, media and product condition.
Typical applications include piping and pressure equipment. Confirm suitability against the project specification, temperature, media and product condition.
Typical applications include bolting and fasteners. Confirm suitability against the project specification, temperature, media and product condition.
Consider corrosion environment, temperature, product form, fastener size, heat treatment and the governing specification when selecting AISI 304H.
Corrosion Resistance: AISI 304H is intended for corrosion-resistant service, but actual performance depends on the environment, concentration, temperature and surface condition.
Mechanical Requirements: use certified mechanical properties for the exact grade, product form and condition; do not substitute generic family values for design allowables.
The commonly listed Werkstoff / EN cross-reference for AISI 304H is 1.4948. Treat this as a grade comparison, not a guarantee of interchangeability. Verify chemistry, product form, condition and governing specification against the supplier certificate before substitution.
Typical applications include general fabrication, food and process equipment, piping and pressure equipment. Suitability depends on service environment and product condition.
Yes. Tensile strength, yield strength, elongation and hardness vary with product form, heat treatment, cold work, section size and the governing specification.
