ASTM B265-25 PDF

Full title and description

Standard Specification for Titanium and Titanium Alloy Strip, Sheet, and Plate — ASTM B265-25. This specification covers annealed titanium and titanium-alloy flat products (strip, sheet and plate), defining applicable grades (with UNS designations), chemical composition limits, mechanical property requirements, dimensional and surface condition tolerances, required tests (including bend and product analysis), sampling/acceptance rules, marking, certification and packaging.

Abstract

ASTM B265-25 is a material specification that establishes the requirements for annealed titanium and titanium-alloy strip, sheet and plate intended for industrial, chemical, marine, aerospace and medical-related applications. The standard lists permitted grades (including commercially pure and alloyed grades such as Grade 1, 2, 3, 4, 5 (Ti‑6Al‑4V) and ELI variants), gives chemical composition and mechanical property limits, specifies test methods (chemical analysis, bend test, tensile requirements), and sets out inspection, sampling, marking and packaging practices to ensure consistency between manufacturer and purchaser.

Scope

ASTM B265-25 applies to annealed titanium and titanium-alloy strip, sheet and plate. It covers commercially pure titanium grades and numerous titanium alloys identified by grade and UNS designation, establishes required chemical composition limits for the covered elements, and defines mechanical-property requirements and minimum tests. Products are furnished in specified surface conditions (for example, annealed, descaled, sandblasted or ground) and in agreed dimensions; the specification addresses sampling for product analysis, special test requirements (such as bend testing for sheet and strip), and acceptance/rejection criteria.

Key topics and requirements

• List of applicable grades and corresponding UNS designations for commercially pure and alloyed titanium (common examples: Grade 1, Grade 2, Grade 2H, Grade 3, Grade 4, Grade 5 (Ti‑6Al‑4V), Grade 9, Grade 12, Grade 23 (ELI), etc.).
• Chemical composition limits for elements (Ti plus specified maximums/limits for O, N, H, Fe, C and alloying elements such as Al, V, Mo, Ni, Pd, Ru, Nb, Zr, Co, Sn, Si, Cr).
• Mechanical property requirements (tensile strength, yield, elongation) and optional higher‑strength designations (H variants) where specified.
• Bend test criteria for sheet and strip (cold bend without fracture on the outside surface) and other mechanical checks as required.
• Product analysis and sampling procedures with tolerances for laboratory-to-laboratory variation; guidance on sample cutting to avoid contamination (control of oxygen, nitrogen and hydrogen pickup).
• Dimensional tolerances, permitted finishes and surface condition requirements; flatness and finish options by agreement between purchaser and supplier.
• Inspection, certification and marking requirements, plus packaging and handling instructions to protect product integrity in transit.

Typical use and users

ASTM B265-25 is used by material specifiers, purchasing agents, quality and metallurgical engineers, manufacturers of titanium strip/sheet/plate, heat exchanger and chemical‑process equipment designers, aerospace and marine component manufacturers, and medical device makers (for non-implant and certain implant applications when combined with medical-specific standards). Typical applications include corrosion‑resistant process equipment, aircraft structural components, heat exchangers, marine hardware and precision components where titanium's strength-to-weight and corrosion resistance are required.

Related standards

Closely related and often used together with ASTM B265 are ASME SB‑265 (corresponding ASME designation), material standards for titanium used in medical applications (for example ASTM F67 and ASTM F136 for certain implant-grade materials), applicable AMS and industry product/process specifications, and referenced test-method standards cited within B265 for chemical and mechanical testing. Users should consult these allied standards where application-specific requirements (medical, aerospace) or alternate designations are needed.
