Full title and description
St ASTM A442/A442M-90 — Standard Specification for Pressure Vessel Plates, Carbon Steel, Improved Transition Properties. Specification that defined chemical, mechanical and toughness requirements for carbon steel plates intended for welded pressure vessels with improved low‑temperature transition behavior (designation year 1990).
Abstract
This withdrawn ASTM specification (A442/A442M‑90) established requirements for carbon steel plates used in welded pressure vessel construction where improved transition‑temperature toughness was required. The standard described permitted steelmaking practices, grade designations, dimensional limits and the relevant mechanical and impact properties for plates intended for moderate and lower temperature service.
General information
- Status: Withdrawn / inactive (withdrawn 1991).
- Publication date: 1990 (designation A442/A442M‑90; published late 1990).
- Publisher: ASTM International (formerly American Society for Testing and Materials).
- ICS / categories: 23.020.30 (Pressure vessels); 77.140.30 (Steels for pressure purposes) — metallurgy / pressure vessel materials.
- Edition / version: A442/A442M‑90 (1990 edition).
- Number of pages: 2 (short specification).
Scope
The specification covered carbon steel plates intended for welded pressure vessels that require improved low‑temperature transition properties. It defined available grades, permitted steelmaking practice for thinner plates, thickness limits typically provided in practice, and the required mechanical and impact‑toughness characteristics. The standard presented values in both inch‑pound and SI units (each system to be used independently).
Key topics and requirements
- Material application: carbon steel plates for welded pressure vessels.
- Improved low‑temperature transition properties (impact toughness requirements and transition temperature control).
- Grade designations and permitted steelmaking practices (semi‑killed practice allowed for plates up to specified thickness).
- Thickness guidance and practical limits (typical supply limited by practice; see standard for exact limits—commonly up to ~1 in / 25 mm with practical limits noted up to about 1½ in / 38–40 mm).
- Separate inch‑pound and SI unit specifications (not direct conversions; each system is independent).
- Referenced use in pressure‑vessel codes (materials to be coordinated with ASME Code requirements where applicable).
Typical use and users
Used historically by pressure‑vessel fabricators, material procurement/specification engineers, code authorities and inspectors specifying plate material for welded pressure vessels requiring improved low‑temperature toughness. Today users are more likely to consult current ASTM/ASME materials standards and pressure‑vessel codes for equivalent or superseding material requirements.
Related standards
Examples of related or commonly referenced standards include ASTM A516/A516M (carbon steel plates for moderate‑ and lower‑temperature service), other ASTM pressure‑vessel plate specifications, the ASME Boiler and Pressure Vessel Code (Section II materials, Section VIII construction rules), and regional standards for steel plates for pressure purposes (for example EN/ISO standards on steel plates for pressure equipment).

FAQ
Q: What is this standard?
A: ASTM A442/A442M‑90 is a short ASTM specification that specified requirements for carbon steel plates with improved low‑temperature transition properties intended for welded pressure vessels (designation year 1990).
Q: What does it cover?
A: It covers chemical, mechanical and impact‑toughness requirements, permitted steelmaking practice for certain thicknesses, grade designations and practical thickness guidance for carbon steel pressure‑vessel plates where improved transition‑temperature behavior is needed.
Q: Who typically uses it?
A: Pressure‑vessel manufacturers, procurement and materials engineers, inspectors and code authorities who specify or verify plate materials for welded pressure vessels—historically-used by those needing improved low‑temperature toughness.
Q: Is it current or superseded?
A: The A442/A442M‑90 edition is withdrawn (withdrawn in 1991) and is inactive. Users should consult current ASTM and ASME BPVC material specifications (for example ASTM A516 series and the ASME Section II material lists) or equivalent regional standards for present day requirements.
Q: Is it part of a series?
A: It belonged to the family of ASTM specifications for pressure‑vessel plates (A‑series for steel plates). Related ASTM and ASME material specifications and their ASME counterparts (SA/SA‑M designations in ASME Section II) form the broader series of materials standards used for pressure vessels.
Q: What are the key keywords?
