ASME BPVC 2025 Section II part D (metric) PDF

Full title and description

ASME Boiler and Pressure Vessel Code (BPVC) — Section II, Materials, Part D: Properties (Metric), 2025 Edition. This volume provides metric unit tables and reference data of material properties used throughout the BPVC, including allowable/design stresses, tensile and yield strengths, physical properties and external pressure charts, plus appendices with criteria and procedures for establishing allowable stresses and approving new materials.

Abstract

Part D (Metric) of ASME BPVC Section II is a service/reference section for the Boiler & Pressure Vessel Code that compiles standardized material property tables in metric units. It supplies the numerical property values, design and allowable stresses, physical data and external pressure charts needed by designers, fabricators and inspectors to apply BPVC construction requirements consistently. Appendices explain the bases for stresses and provide procedures for adding or qualifying new materials.

Scope

This metric edition of Section II, Part D provides standardized metric-unit property tables and reference charts for materials used in boilers and pressure vessels. It includes allowable, design, tensile and yield stress values at specified temperatures, physical property tables (density, modulus, thermal expansion, conductivity), external pressure charts and the appendices that define methodologies for establishing allowable stresses, developing external pressure curves, and documenting and approving new materials for BPVC use. It is intended as a cross-reference resource for the other BPVC construction Sections and for regulatory and conformity use.

Key topics and requirements

• Metric-unit allowable stress tables for ferrous and selected nonferrous materials across temperature ranges.
• Tensile and yield strength data, including temperature dependence where specified.
• Physical property tables: density, Young’s modulus, Poisson’s ratio, thermal expansion, thermal conductivity, specific heat.
• External pressure (collapse) charts and tabulated data for cylindrical and spherical shells.
• Appendices: methodologies and criteria for establishing allowable stresses and external pressure curves.
• Procedures and information requirements for submission and approval of new materials for inclusion in the Code.
• Cross-references to material specifications in Section II Parts A, B and C and to relevant ASME construction Sections.

Typical use and users

Used by pressure-vessel and boiler designers, mechanical engineers, materials engineers, fabricators, code inspectors, authorized inspection agencies, certifying bodies and regulators. Typical applications include selection of material allowable stresses for design calculations, checking material suitability at operating temperatures, referencing external pressure charts for cylindrical/spherical components, and preparing submissions for material approval under the BPVC process.
