Full title and description

ASTM B536-19 — Standard Specification for Nickel‑Iron‑Chromium‑Silicon Alloys (UNS N08330 and UNS N08332) Plate, Sheet, and Strip. The specification defines chemical, mechanical, and metallurgical requirements for these nickel‑iron‑chromium‑silicon alloys intended for heat‑resisting applications and general corrosive service.

Abstract

This specification covers plate, sheet, and strip forms of UNS N08330 and UNS N08332 alloys, specifying permitted chemical composition ranges, required tensile properties at room temperature, annealing/heat‑treatment notes, and certain microstructural requirements (for example, an average grain size requirement for annealed UNS N08332). It is principally used to ensure materials supplied for heat‑resisting and corrosive environments meet minimum acceptance criteria.

General information

• Status: Withdrawn as originally published (B536-19); a revised/reissued record for B536 with a 2025 designation has been recorded in standards databases and work to revise the document was active into 2026.
• Publication date: Original designation B536-19 published 01 January 2019 (designation B536-19). A reissued/revised record appears with a 2025 entry (01/07/2025) in standards catalogs.
• Publisher: ASTM International.
• ICS / categories: 77.150.40 (Nickel and chromium products / corrosion‑ and heat‑resisting alloys).
• Edition / version: B536‑19 (2019) — reference to later 2025 reissue in catalogs (B536‑19(2025)).
• Number of pages: Typically published as a short specification (reported as 3 pages in catalog listings for the 2019/2025 record).

Scope

The standard applies to nickel‑iron‑chromium‑silicon alloys UNS N08330 and UNS N08332 in plate, sheet, and strip form intended for applications requiring heat resistance and general corrosion resistance. It sets requirements for chemical composition, tensile properties at room temperature, heat treatment/annealing instructions (including a grain‑size requirement for annealed UNS N08332), and acceptance testing methods for delivered material. The values and limits are provided in inch‑pound units (with SI conversions for information where applicable).

Key topics and requirements

• Designated alloys: UNS N08330 and UNS N08332 (chemical composition limits and element ranges specified).
• Product forms covered: plate, sheet, and strip; typical thickness/width limits and product finishes referenced.
• Mechanical property requirements: minimum tensile and yield properties at room temperature and elongation limits for acceptance.
• Heat treatment/annealing: annealed condition requirements and heat‑treatment guidance; grain‑size requirement for annealed UNS N08332.
• Testing and acceptance: mandatory chemical analysis and mechanical testing; hardness or other supplemental tests when specified in purchase order or contract.
• Intended use cases: heat‑resisting and general corrosive service environments (industrial process equipment, furnace components, and similar applications).

Typical use and users

Material specifiers, procurement and quality engineers, alloy plate/sheet producers, fabricators and manufacturers of heat‑resistant components, and inspectors in power generation, chemical processing, and related heavy industries use this specification to ensure delivered plates, sheets, and strips of UNS N08330/N08332 meet minimum metallurgical and mechanical requirements for service.

FAQ

Q: What is this standard?

A: ASTM B536‑19 is (was) the ASTM specification for nickel‑iron‑chromium‑silicon alloys UNS N08330 and UNS N08332 in plate, sheet, and strip form, defining required chemistry, mechanical properties, and basic processing/acceptance requirements for these materials.

Q: What does it cover?

A: It covers product forms (plate, sheet, strip), the two alloy designations (UNS N08330 and N08332), limits on chemical composition, required tensile properties at room temperature, annealing/heat‑treatment notes (including grain‑size for annealed N08332), and testing/acceptance provisions for procurement and inspection.

Q: Who typically uses it?

A: Material suppliers, fabricators, metallurgists, procurement and quality teams in industries requiring heat‑resisting or corrosion‑resistant nickel alloys (for example chemical processing, power generation, furnace components, and high‑temperature industrial equipment).

Q: Is it current or superseded?

A: The 2019 record (B536‑19) is listed as withdrawn in standard catalog listings; catalog entries also show a 2025 reissue/revision record.
