GOST 5632-72 PDF

Full title and description

GOST 5632-72 — "Стали высоколегированные и сплавы коррозионно-стойкие, жаростойкие и жаропрочные. Марки" / "High-alloy steels and corrosion‑resistant, heat‑resisting and heat‑resistant alloys — Grades". The standard lists steel and alloy grades (including many chromium‑nickel and nickel‑base grades), their designation and normative application notes.

Abstract

GOST 5632-72 defines grades of wrought high‑alloy stainless, corrosion‑resistant and heat‑resisting steels and nickel‑base alloys, providing grade names/designations and cross‑references to chemical and application groups. It is a materials classification standard used to identify and match alloy grades for industrial, chemical and high‑temperature applications.

General information

• Status: Withdrawn / superseded in practice by later revisions (see GOST 5632-2014) but historically retained in some registries and specific usages (including restricted/restored use in certain Russian nuclear contexts).
• Publication date: Original designation year 1972 (GOST 5632‑72); published editions and reprints circulated in the 1970s (records show publication entries from the mid‑1970s).
• Publisher: State standards body of the USSR (Gosstandart); successor bodies / national standards organizations (e.g., Rosstandart) manage later revisions and restorations.
• ICS / categories: 77.080.20 — Steels; metallurgy and metallic materials (high‑alloy and corrosion/heat‑resisting steels).
• Edition / version: Designation GOST 5632-72 (original). A consolidated modern revision exists as GOST 5632-2014 which replaced/updated the grades and presentations for current use.
• Number of pages: Varies by publication/format — archived/electronic copies and reprints show roughly 60–64 pages in many commercial listings; some national catalog entries show different pagination for local reprints.

Scope

The standard applies to wrought (deformable) high‑alloy steels and alloys — primarily chromium‑nickel stainless steels and nickel‑base alloys — intended for service in corrosive environments and at elevated temperatures. It sets out the list of grades (markings), groups them by alloy system and gives normative references for designation and interchangeability with other marking systems. The scope covers grade identification rather than exhaustive specification of all mechanical testing; chemical ranges and typical intended application classes are provided.

Key topics and requirements

• Official list of high‑alloy, corrosion‑resistant and heat‑resisting steel and alloy grades (chromium‑nickel and nickel‑base systems).
• Designation (marking) rules and correspondence to national marking conventions used in the USSR/CIS.
• Cross‑references and equivalence notes to some international/common grades (AISI/EN designations are commonly referenced in modern crosswalks).
• Notes on permitted uses, special grades for heat‑resistance or specific environments, and amendments recorded in subsequent issues.

Typical use and users

Primary users are metallurgists, materials engineers, procurement/specification engineers, steel and alloy manufacturers, and maintenance engineers in chemical, power generation, petrochemical and high‑temperature process industries. Standard is also referenced by technical libraries and regulatory bodies when matching historical material grades or verifying legacy equipment materials, including certain controlled uses in nuclear facility contexts.

Related standards

Related and successive documents include earlier GOST versions (e.g., GOST 5632-61 referenced as a predecessor) and the later consolidated revision GOST 5632-2014 which updates grade lists and presentation. Other associated standards cover technical conditions, mechanical testing, and specific heat‑resistant steel specifications (various GOST/ISO/EN cross‑references appear in annexes and crosswalk tables in modern catalogs).

FAQ

Q: What is this standard?

A: GOST 5632-72 is a Soviet/Russian national standard that lists high‑alloy, corrosion‑resistant and heat‑resisting steel and alloy grades and provides designation/marking guidance for those grades. It is primarily a materials‑classification/grade list rather than a full test specification.

Q: What does it cover?

A: It covers wrought (deformable) stainless and heat‑resisting steels and nickel‑base alloys — naming the grades and grouping them by composition and intended application (corrosion resistance, heat resistance, creep resistance). It includes grade designations used historically in the USSR/CIS.

Q: Who typically uses it?

A: Metallurgists, materials and design engineers, steel producers and procurement/specification teams who need to identify or match alloy grades (particularly when dealing with legacy equipment, imports/exports, or cross‑referencing older documentation). Technical libraries and regulatory specialists may also consult it for historical or compliance reasons.

Q: Is it current or superseded?

A: The original GOST 5632-72 has been superseded in practice by later revisions and consolidated editions (notably GOST 5632-2014). Commercial catalogs list the 1972 document as withdrawn in many jurisdictions, although some registries note restricted/restored usage for particular contexts (for example, controlled use in certain nuclear facilities). Users should refer to the latest national/regional version (GOST 5632-2014 or applicable national adoption) for current requirements.

Q: Is it part of a series?

A: Yes — GOST 5632-72 is part of a broader group of metallurgy standards covering steels and alloys (other GOSTs cover related technical conditions, testing methods and specific heat‑resistant/structural steel specifications). It also has predecessor and successor GOST documents that together form the national system for alloy grade designation.

Q: What are the key keywords?

A: High‑alloy steels, stainless steels, corrosion‑resistant, heat‑resisting, alloy grades, steel marking, chromium‑nickel steels, nickel alloys.
