Full title and description

Standard Specification for Pressure Vessel Plates, Low‑Carbon Age‑Hardening Nickel‑Copper‑Chromium‑Molybdenum‑Columbium (Niobium) Alloy Steel — ASTM A736/A736M‑17. The specification covers chemical composition, heat treatment (quenching and precipitation aging), mechanical properties (tensile and notch‑toughness), and supply conditions for low‑carbon age‑hardening alloy steel plates intended for welded pressure vessels and piping components.

Abstract

This specification defines requirements for low‑carbon, age‑hardening nickel‑copper based alloy steel plates (niobium‑bearing) used in welded pressure‑containing equipment. It specifies available grades/classes, required heat treatment procedures (quenched and precipitation heat treated), minimum tensile strengths by thickness, chemical composition limits, and applicable mechanical test requirements. The original A736/A736M‑17 text is brief (3 pages) and expressed in both inch‑pound and SI units.

• Number of pages: 3 pages (short specification).

Scope

The specification covers low‑carbon age‑hardening alloy steel plates intended for welded pressure vessels and piping components. It addresses two alloy families (nickel‑copper‑chromium‑molybdenum‑columbium (niobium) and variants including manganese in certain grades), and provides requirements for heat treatment (quenched and precipitation aged), tensile properties (minimum tensile strengths dependent on plate thickness), and notch‑toughness where applicable. Plates are supplied in designated grades/classes (historically Grade A, Class 3 in the 2017 text) and the document is published in both inch‑pound and SI (“M”) units.

Key topics and requirements

• Alloy chemistry: specified limits for C, Mn, Si, P, S, Cr, Ni, Mo, Cu and columbium (niobium) to ensure age‑hardening response and weldability.
• Heat treatment: quenching and precipitation‑ageing (age‑hardening) schedules and acceptance criteria for Class and Grade designations.
• Mechanical properties: minimum tensile strengths (e.g., 85 ksi for thinner plates; lower minima for thicker plates) and required tests (tension, notch‑toughness where specified).
• Supply conditions: plate form, maximum practical thickness (limited by chemistry and heat‑treatment capability), and unit designation in inch‑pound or SI units.
• Applicability: intended specifically for welded pressure vessels and related piping components requiring age‑hardening alloy steels.

Typical use and users

Used by material engineers, pressure‑vessel designers, fabricators, inspection and quality personnel, and procurement specialists in industries such as petrochemical, power generation, and industrial gas processing where welded pressure vessels require higher strength and specific ageing characteristics. Also used by steel producers and plate suppliers to certify material to purchaser specifications.

Related standards

ASTM A736/A736M is maintained by ASTM Committee A01 (Subcommittee A01.11). The 2017 edition has been superseded by ASTM A736/A736M‑25 (the current active edition as of 2025). Related standards to consult for pressure‑vessel plate materials and fabrication include other ASTM pressure‑vessel material specifications and applicable code rules (ASME Boiler & Pressure Vessel Code, relevant material specs such as other A‑series steel plate standards), along with previous A736 editions (A736/A736M‑12, A736/A736M‑03, etc.) for historical comparisons.

FAQ

Q: What is this standard?

A: ASTM A736/A736M‑17 is a short ASTM specification (3 pages) that defines requirements for low‑carbon age‑hardening nickel‑copper‑based alloy steel plates intended for welded pressure vessels and piping components.

Q: What does it cover?

A: It covers chemical composition limits, designated grades/classes, quench and precipitation‑age heat treatment procedures, minimum tensile strengths (varying with thickness), and mechanical testing requirements (tension and notch‑toughness where required). The specification is provided in inch‑pound and SI (“M”) units.

Q: Who typically uses it?

A: Material engineers, fabricators and welders who specify or supply pressure‑vessel plate, purchasers and quality/inspection teams who verify compliance, and steel producers supplying plates for pressure‑containing applications.

Q: Is it current or superseded?

A: The 2017 edition (A736/A736M‑17) has been superseded — the active current edition is ASTM A736/A736M‑25 (published/implemented in 2025). For new procurements and design references, use the 2025 edition unless a purchaser specifically requires the 2017 text.

Q: Is it part of a series?

A: Yes — A736/A736M is part of ASTM’s collection of material specifications for steels used in pressure vessels (Book of Standards volume group for pressure‑vessel steels) and is maintained by Committee A01 (Subcommittee A01.11). There are prior and subsequent revisions (for example A736/A736M‑12, A736/A736M‑03, and the 2025 revision).

Q: What are the key keywords?

A: Pressure vessel plate; age‑hardening; low‑carbon alloy steel; nickel‑copper; columbium (niobium); quench and age; tensile strength; ASTM A736; A736M.
