The American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (BPVC) is a widely adopted standard for the design, fabrication, inspection, and testing of boilers and pressure vessels. Section II of the ASME BPVC is a critical component of the code, as it provides the material specifications for the construction of boilers and pressure vessels. In this blog post, we will focus on ASME BPVC Section II Part A 2019 PDF, providing an overview of its contents, significance, and application.
Specifications for steel plates used to roll vessel shells and form heads (e.g., SA-516, SA-285).
Refinements were made to mechanical testing guidelines, particularly regarding how specimen locations are chosen in heavy forgings and thick plates.

The ASME Boiler and Pressure Vessel Code (BPVC) is a set of standards for the design, fabrication, inspection, and testing of boilers and pressure vessels. Section II of the BPVC is divided into two parts: Part A (Materials) and Part B (Nonferrous Materials).
Understanding ASME BPVC Section II Part A (2019 Edition): A Comprehensive Guide to Ferrous Material Specifications
The American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (BPVC) is the global standard governing the design, fabrication, and inspection of boilers and pressure vessels. Within this framework, Section II plays a critical role by defining the material specifications permissible for construction.
The 2019 edition of BPVC Section II Part A introduced several critical revisions. If you are evaluating a , be aware of the following changes from the 2017 edition: The American Society of Mechanical Engineers (ASME) Boiler
Using the correct 2019 PDF version of Section II Part A ensures that all materials used in construction meet the mandated safety factors defined in the 2019 ASME Code updates.
The book also contains mandatory and non-mandatory appendices that detail guidelines for adopting new materials, formatting requirements, and the basis for establishing chemical and mechanical properties. 3. Crucial Elements within a Material Specification
The ASME BPVC Section II Part A 2019 PDF has numerous applications across various industries, including:
For any professional involved in the specification, manufacturing, or inspection of pressure equipment, a thorough understanding and correct application of the 2019 edition of Section II, Part A is indispensable. As the industry looks to newer editions (2021, 2023, 2025), the 2019 edition stands as a definitive snapshot of ferrous material standards in the late 2010s—a valuable resource for years to come. Specifications for steel plates used to roll vessel
Structural bars and high-strength fasteners used for pressure-retaining closures (e.g., SA-193, SA-320).
Because ASME publishes a new edition of the BPVC every two years (the 2019 edition was followed by the 2021, 2023, and 2025 editions), the 2019 version is considered a historical code text. However, it remains legally and contractually binding for:
: Remember that Part A provides the material specification , but the allowable design stresses across various temperatures must be extracted from ASME Section II Part D .
