Full title and description

ASTM B36/B36M-23 — Standard Specification for Brass Plate, Sheet, Strip, and Rolled Bar. This ASTM International standard specifies required alloys (UNS numbers), tempers, mechanical properties, hardness and grain-size considerations, and ordering information for brass plate, sheet, strip, and rolled bar products used in engineering and manufacturing applications.

Abstract

This specification establishes requirements for brass (copper‑zinc alloys) plate, sheet, strip, and rolled bar made from the listed UNS alloys (C21000, C22000, C22600, C23000, C24000, C26000, C26800, C27200, and C28000). It defines available product tempers (hot‑rolled, rolled, annealed, annealed‑to‑temper), required tensile strengths, Rockwell hardness limits, grain‑size guidance, dimensions/tolerances and ordering information. Both inch‑pound and SI units are provided (each system to be used independently).

Scope

The standard applies to brass plate, sheet, strip, and rolled bar produced from specified copper‑zinc UNS alloys (C21000, C22000, C22600, C23000, C24000, C26000, C26800, C27200, and C28000). It covers permitted tempers, dimensional and tolerance guidance, minimum mechanical property requirements (tensile strength, yield where specified), acceptable Rockwell hardness ranges and grain size considerations for conformance. Units are provided in both inch‑pound and SI systems; the two systems are to be used independently. Plates are commonly available in hot‑rolled temper; other tempers and processing conditions are described in the specification.

Key topics and requirements

• List of covered alloys by UNS designation (C21000, C22000, C22600, C23000, C24000, C26000, C26800, C27200, C28000).
• Permitted product forms: plate, sheet, strip, and rolled bar, with stated dimensional ranges and tolerances.
• Specified tempers: hot‑rolled, rolled, annealed, and annealed‑to‑temper (details for temper identification and acceptance criteria).
• Mechanical property criteria: required tensile strengths (and where applicable other strength limits) for each alloy/temper combination.
• Hardness and grain‑size guidance: Rockwell hardness acceptance limits and use of grain‑size as a supplementary check on temper and processing.
• Units and measurement: separate inch‑pound and SI units (each system is independent; do not mix values from different systems).
• Ordering information and required purchaser options (alloy, temper, dimensions, certifications, testing requirements).
• References and normative cross‑references to related ASTM terminology and product specifications.

Typical use and users

This standard is used by material specifiers, purchasing and procurement departments, manufacturers of brass plate/sheet/strip/rolled bar, quality and inspection engineers, metallurgists, and design engineers who must select or verify brass materials for components, housings, fittings, architectural elements, and general fabrication. It is used to define acceptance criteria for incoming material and to communicate required alloy and temper to suppliers.

Related standards

Relevant related documents and cross‑references include the prior edition ASTM B36/B36M‑18 (superseded by this revision) and other ASTM documents referenced in the standard (for example, ASTM Terminology B846 and various B‑series product and test standards that deal with copper and copper alloys and product testing). The specification also notes where supplementary requirements from other plate/sheet specifications (such as B248/B248M in related contexts) may apply.
