GOST 5632-2014 PDF

Full title and description

GOST 5632-2014 — "Alloyed stainless steels and alloys: corrosion-resistant, heat-resistant and creep-resistant. Grades" (Russian: Легированные нержавеющие стали и сплавы коррозионно-стойкие, жаростойкие и жаропрочные. Марки). The standard establishes grade designations, classification, compositional limits and general technical requirements for wrought alloyed stainless steels and nickel/iron‑nickel based alloys intended for use in corrosive environments and at elevated temperatures.

Abstract

GOST 5632-2014 defines the system of grades for wrought alloyed stainless steels and corrosion/heat/creep resistant alloys, specifies classification by structural group (austenitic, ferritic, martensitic, duplex and mixed types), gives chemical composition limits for grades, and sets out requirements for marking, sampling and references to test methods. It replaces the earlier 1972 edition and brought Russian interstate requirements in line with modern metallurgy practice for high‑alloy steels and nickel alloys.

General information

• Status: Active / In force (replaces GOST 5632‑72; has subsequent informational updates listed in official bulletins).
• Publication date: Approved 24 October 2014; put into effect 1 January 2015.
• Publisher: Interstate standard published via Russian standardization bodies (Standartinform / Federal Agency for Technical Regulation and Metrology — Rosstandart).
• ICS / categories: 77.080.20 (metallurgy — stainless steels and alloys).
• Edition / version: 2014 edition (GOST 5632‑2014); supersedes GOST 5632‑72; amendments and information notices have appeared in subsequent IUS bulletins.
• Number of pages: Approximately 54 pages (electronic/text editions vary slightly by publisher).

Scope

The standard applies to alloyed, deformable (wrought) stainless steels and to corrosion‑resistant, heat‑resistant and creep‑resistant alloys on iron‑nickel and nickel bases. It is intended for steels and alloys used in atmospheres, soils, acidic/alkaline environments, salt media and at elevated service temperatures; scope includes grade designation, compositional limits and classification but delegates detailed product dimensions and specific product standards to other GOSTs.

Key topics and requirements

• Classification of grades by structural type: martensitic, ferritic, austenitic, austenite‑ferritic (duplex), austenite‑martensitic and transitional structures.
• Compositional limits for major alloying elements (Cr, Ni, C, Mo, Ti, Nb, etc.) for each grade, with declared mass fraction ranges and residual element considerations.
• Designation and marking rules for grades and batches to ensure traceability and conformity.
• References to sampling and analytical methods for chemical composition and to mechanical/property testing standards used for acceptance (normative references within the standard).
• Guidance on intended application areas (corrosive media, high‑temperature service, creep applications) and on heat treatment effects relevant to structure and properties.

Typical use and users

Engineers, metallurgists, quality and procurement specialists in steel production and metalworking, manufacturers of pressure equipment, heat exchangers and chemical processing equipment, oil & gas and power industry designers, and testing and certification bodies use GOST 5632‑2014 to specify material grades, verify composition and ensure consistent material selection for corrosion‑ or temperature‑sensitive applications. Suppliers of stainless bars, plates, pipes and forgings reference the standard when listing grades for sale.

Related standards

Commonly referenced and related documents include earlier and product‑specific GOSTs and interstate standards for testing, product specifications and fasteners—examples: GOST 5632‑72 (superseded), GOST 5949‑2018 (specifications for corrosion‑resistant and heat‑resistant steels and alloys in products), GOST ISO 3506 series (mechanical properties of corrosion‑resistant fasteners), and various GOSTs covering pipes, sheets and acceptance/marking rules. Users should consult product and testing standards referenced in the normative references clause of GOST 5632‑2014 for complete compliance.

FAQ

Q: What is this standard?

A: GOST 5632‑2014 is the Russian/interstate standard that defines grades, classification and compositional requirements for alloyed stainless steels and nickel/iron‑nickel based corrosion‑, heat‑ and creep‑resistant alloys.

Q: What does it cover?

A: It covers grade designations, structural classification (austenitic, ferritic, martensitic, duplex and mixed types), chemical composition limits for listed grades, marking and references to sampling and test methods; it does not replace product‑specific dimensional standards but provides the material grade framework for many product GOSTs.

Q: Who typically uses it?

A: Material engineers, steel producers and processors, designers in chemical, oil & gas and power sectors, procurement and quality control departments, and conformity assessment bodies use it to select and verify stainless steel and alloy grades.

Q: Is it current or superseded?

A: GOST 5632‑2014 is the current 2014 edition that superseded GOST 5632‑72; it entered into effect on 1 January 2015 and remains in force with information notices/amendments recorded in official bulletins. Users should check official registries or national standardization bulletins for the latest amendment status.

Q: Is it part of a series?

A: It functions as a central grade/specification standard within a family of metallurgical and product GOSTs: product standards (pipes, sheets, bars), testing standards and related GOST/ISO documents (for example the GOST ISO 3506 series for fasteners) are commonly used together with GOST 5632‑2014. Consult the normative references section of the standard for the complete list.
