The 2019 edition saw the addition of new grades of steel designed for higher efficiency in power plants and advanced nuclear applications. This includes newer, creep-strength enhanced ferritic steels that allow power plants to operate at higher temperatures with thinner material walls.
: Covers ferrous metals, including carbon steel, alloy steel, and stainless steel.
Section II Part A contains the material specifications for ferrous materials (iron and steel) used in the construction of pressure-retaining equipment. These specifications are designated by (e.g., SA-516 for carbon steel plate) and are largely identical to or based on ASTM standards.

The remains the gold standard for ferrous material specifications. Whether you are specifying plate for a new pressure vessel or reviewing MTRs for a repair job, adhering to this code is non-negotiable for safety and compliance.
The 2019 PDF of Section II Part A covers thousands of pages of technical data, organized to ensure every piece of steel meets rigorous safety standards. Each specification typically includes: 2025 ASME BPVC
One pain point of the digital version is the lack of a hyperlinked index in older PDFs. Here is a pro-tip workflow:
The ASME BPVC is updated every two years. The 2019 edition is a significant update from the 2017 edition, and it includes several important modifications to Section II, Part A. The 2019 edition saw the addition of new
Historically, ASME material specifications are based on ASTM standards. In the 2019 edition, ASME continued its practice of adopting the latest ASTM versions while modifying them to suit BPVC safety requirements. Engineers using the 2019 version will notice updated chemical compositional limits and testing methods that reflect current metallurgical science.
Its role is strictly supportive; it doesn't stand alone but is a "Service Section" referenced by other parts of the BPVC. For example, a construction section like Section VIII (Pressure Vessels) will direct you to a specific "SA" number in Part A to find the allowed material for a vessel component.
For professionals working with ferrous materials, Part A (which you often search for) is of paramount importance.

Using the correct material is the first step toward a safe pressure vessel. Section II Part A serves as the foundation for the design rules found in and Section I (Power Boilers) .
Specifications for forged and cast components used in piping systems and pressure vessel connections (e.g., SA-105, SA-182).
: If you are a student or faculty member, many university libraries provide access to the ASME BPVC database via institutional logins, which may allow viewing or downloading for educational purposes.
