ASTM A516 Grade 70 Pressure Vessel Steel
ASTM A516 Grade 70 is one of the most common carbon-manganese pressure-vessel plate grades for moderate- and lower-temperature service.
Grade overview
Supplied to controlled chemistry and mechanical properties, commonly in normalized condition when required by thickness, code or purchase specification.
Typical applications
Pressure vessels, separators, columns, boilers, storage equipment and process-industry pressure components.
Equivalent / related designations
ASME SA-516 Grade 70 is the pressure-code material designation commonly encountered in ASME fabrication. It should not be substituted with a structural grade based only on similar strength.
Common manufacturers and supply
Produced by qualified heavy-plate mills including Dillinger, Industeel/ArcelorMittal, POSCO, Nippon Steel, JFE, JSW, SAIL and major Chinese plate producers.
Fabrication and selection notes
Confirm the exact product standard, edition, dimensions, delivery condition, mechanical properties, impact requirements, heat treatment, welding procedure, corrosion environment and certification. A grade name alone is not sufficient for procurement or design approval.
QA/QC documentation
For critical service, verify heat number traceability, mill test certificate, chemical analysis, tensile/impact results where required, NDT, heat-treatment record and project-specific third-party inspection requirements.
Element Folio engineering reference. Values and requirements vary by standard edition, product form and manufacturer; always verify the latest governing specification.
