ASME BPVC 2025 Section II part A-2 PDF

Full title and description

St ASME BPVC 2025 — Boiler & Pressure Vessel Code, Section II: Materials — Part A-2 (Ferrous Material Specifications, Volume 2). This product is the second volume of ASME BPVC Section II Part A and contains ferrous material specifications (SA-designated) covering the later-numbered specifications included in the 2025 edition; it is intended as a service reference for designers, fabricators, inspectors and material purchasers who require ASME/ASTM-aligned ferrous material requirements.

Abstract

Part A-2 of ASME BPVC Section II (2025) provides prescriptive specifications for ferrous materials used in boilers, pressure vessels and related pressure-containing equipment. The volume includes chemical and mechanical property requirements, permitted product forms, heat treatment and manufacturing rules, sampling and testing methods, and ASME-specific exceptions or notes to aligned ASTM specifications. It functions as the materials reference called out by multiple BPVC construction sections.

• Publication date: 2025 (2025 edition; commercial product listings and distributor pages list a July 1, 2025 publication for the 2025 BPVC materials set).
• Publisher: ASME International (American Society of Mechanical Engineers).
• ICS / categories: Boilers and heat exchangers; pressure vessels — commonly classified under ICS codes such as 27.060.30 (boilers and heat exchangers) and related pressure-vessel ICS headings.
• Edition / version: 2025 edition — Section II, Part A, Volume 2 (Part A-2).
• Number of pages: Volume 2 (Part A-2) page counts reported by distributors vary; common product listings show Part A-2 ≈ 900–1,000 pages (example listing shows ~943 pages for Part A-2). Users should confirm the exact page count on the purchased format.

Scope

This volume covers the ferrous material specifications included in the second volume of ASME BPVC Section II Part A for the 2025 edition. It includes those SA-designated specifications (chemical composition, mechanical properties, heat treatment, permitted manufacturing processes, sampling and testing, marking and certification requirements) that are required or referenced by construction sections of the BPVC. The scope extends to rolled, forged and cast ferrous product forms where specified and to the ASME exceptions or clarifications to the underlying ASTM or other consensus specifications where shown.

Key topics and requirements

• SA-designated ferrous material specifications (later-numbered SA specifications included in Part A-2).
• Chemical composition limits and product analysis procedures.
• Mechanical property requirements (tensile, yield, elongation, impact where applicable).
• Heat treatment, thermal processing and grain-size requirements.
• Manufacturing, dimensional and finish requirements for plates, pipes, bars, forgings and castings where called out.
• Sampling, test methods, acceptance criteria and inspection documentation.
• Marking, certification and traceability requirements for ASME Code use.
• ASME deviations, exceptions or editorial notes to aligned ASTM specifications included as cover sheets where applicable.

Typical use and users

Used by pressure-vessel and boiler designers, mechanical engineers, material engineers, fabricators, welding and NDE inspectors, quality/inspection departments, procurement/specification writers, and code authorities. Typical use cases include material selection and procurement, verification of material certificates, conformity checks during fabrication, and reference during design reviews where BPVC-mandated materials are required.

Related standards

Closely related to: ASME BPVC Section II Part A-1 (earlier-numbered ferrous specifications), Section II Part B (nonferrous materials), Part C (welding rods, electrodes and filler metals), Part D (material properties), and construction sections that reference Section II (for example Sections I, III and VIII). The BPVC code cases and related ASME construction sections should be consulted together with Section II when specifying materials for code-stamped equipment.

FAQ

Q: What is this standard?

A: It is Volume 2 (Part A-2) of ASME BPVC Section II — the 2025 edition collection of ferrous material specifications (SA-series) used as the BPVC materials reference for boilers and pressure vessels; published under ASME International.

Q: What does it cover?

A: Chemical and mechanical requirements, heat-treatment and manufacturing rules, sampling and test methods, product forms and marking/certification requirements for the SA-designated ferrous specifications contained in the Part A-2 volume; plus any ASME-specific exceptions to referenced consensus specifications included on the cover sheets.

Q: Who typically uses it?

A: Engineers, fabricators, material purchasers, inspectors, and certifying authorities working on boilers, pressure vessels and other ASME-code equipment where BPVC material specifications are required.

Q: Is it current or superseded?

A: This entry describes the 2025 edition — the current BPVC Section II Part A (2025) publication cycle. Users should confirm with ASME or their organization’s code authority for any interim errata or code cases that affect specific specifications.

Q: Is it part of a series?

A: Yes — it is Part A of Section II (Materials) of the ASME Boiler & Pressure Vessel Code. Section II contains multiple parts (A — Ferrous, B — Nonferrous, C — Welding & Filler Metals, D — Properties) and Section II Part A itself is issued in two volumes (commonly shown as Part A-1 and Part A-2 for the complete ferrous specifications set).

Q: What are the key keywords?

A: ASME, BPVC, Section II, Part A-2, ferrous materials, SA specifications, material properties, heat treatment, ASTM-aligned specifications.
