ASME BPVC 2025 Section II. Materials. Part D. Proper ties (Metric) PDF

Full title and description

ASME BPVC 2025 — Section II, Materials, Part D: Properties (Metric). This Service Section of the ASME Boiler and Pressure Vessel Code (BPVC) provides metric-unit tables of material properties used by BPVC construction Sections, including allowable and design stresses, tensile and yield values, physical properties, and external pressure charts, together with appendices that explain criteria for establishing allowable stresses and approval of new materials.

Abstract

Part D (Metric) is a reference volume intended to facilitate selection and application of materials in BPVC designs by publishing standardized, code-approved material property data in metric units. It consolidates stress tables, physical property data, and external pressure information and includes appendices with the bases and procedures for deriving allowable stresses and external-pressure charts. The Section is maintained as part of the BPVC series and is published by ASME.

Scope

Part D (Metric) supplies tabulated material properties for materials called out by other BPVC Sections, enabling designers and inspectors to identify applicable allowable stresses, design stresses, tensile/yield strengths, creep or temperature-dependant data where applicable, physical properties (density, modulus, thermal coefficients), and external-pressure charts and tables used in pressure-vessel design and assessment. The Section also contains appendices describing the technical bases and procedures for deriving allowable stress values and the approval process for new materials to be used within the Code.

Key topics and requirements

• Standardized metric tables of allowable stresses and design stresses for BPVC materials.
• Tensile strength, yield strength, elongation and reduction-of-area reference data in metric units.
• Physical properties (density, Young’s modulus, thermal properties) for referenced materials.
• External pressure charts and the methods/bases for their development.
• Appendices with criteria and procedures for establishing allowable stresses and approving new materials for Code use.
• Cross-references to material specifications in Section II Parts A, B and C (SA/SB/SFA designations) and alignment with commonly referenced ASTM/AWS specifications.

Typical use and users

Used as a reference by mechanical engineers, pressure-vessel designers, fabricators, inspection agencies, code reviewers, materials engineers, and regulators. Typical applications include selecting code-approved materials, determining allowable and design stresses for mechanical and structural calculations, verifying material properties during procurement and inspection, and supporting external-pressure and stability checks for pressure-retaining components.

Related standards

Closely related to the other parts of ASME BPVC Section II (Part A: Ferrous Material Specifications; Part B: Nonferrous Material Specifications; Part C: Welding Rods, Electrodes and Filler Metals) and to the construction Sections of the BPVC (e.g., Section I, Section VIII) that call up material properties and allowable stresses. Many Part D entries cross-reference ASTM and AWS specifications where SA/SB/SFA numbers are harmonized with international material standards.
