AISI 330 Bolting Products
AISI 330 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 330 lists Chromium (Cr): High-temperature oxidation/corrosion resistance; Nickel (Ni): Austenite stabilization and high-temperature performance; Silicon / molybdenum (Si / Mo): May be present depending on grade. Confirm exact limits and analysis tolerances against the governing standard and product form.
The mechanical-property table for AISI 330 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 330: 1.4864. This comparison does not guarantee interchangeability; confirm chemistry, product form and condition against the governing specification.

AISI 330 is a high-nickel chromium-iron alloy used for demanding high-temperature service, especially where carburizing and oxidation resistance are important. Key performance features vary by grade and condition.
AISI 330 is selected when high nickel content is important in service.
The grade provides high-temperature oxidation resistance, subject to product form and specification.
This characteristic supports use of AISI 330 in appropriate industrial environments.
Performance depends on the certified material condition and governing specification.
AISI 330 is selected for bolting and engineered components where its corrosion, temperature or fabrication characteristics match the service environment.
Typical applications include furnace components. Confirm suitability against the project specification, temperature, media and product condition.
Typical applications include heat-treatment fixtures. Confirm suitability against the project specification, temperature, media and product condition.
Typical applications include petrochemical equipment. Confirm suitability against the project specification, temperature, media and product condition.
Typical applications include high-temperature 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 330.
Corrosion Resistance: AISI 330 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 330 is 1.4864. 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 furnace components, heat-treatment fixtures, petrochemical 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.
