GOST 25054-81 PDF

Full title and description

GOST 25054-81 — "Forgings of corrosion-resisting steels and alloys. General specifications" (Russian: Поковки из коррозионно-стойких сталей и сплавов. Общие технические условия). This interstate (GOST) standard establishes general technical conditions, classification and acceptance requirements for forgings made from corrosion‑resistant (stainless and high‑alloy) steels and alloys.

Abstract

GOST 25054-81 defines the technical requirements, classification by groups and grades, dimensional and tolerance rules, mechanical and impact properties, chemical composition limits, marking, inspection and acceptance rules, and packaging/transportation provisions for hot-forged and drop‑forged corrosion‑resistant steel and alloy forgings intended primarily for engineering applications. The standard was issued for application in the USSR and remains referenced in CIS markets with several later amendments.

General information

• Status: Active / effective (limitation of effectiveness lifted per Protocol No. 2‑92 of the Interstate Council; standard retained with amendments).
• Publication date: Approved 21 December 1981; introduced 1 January 1983 (designation year 1981 — "25054‑81").
• Publisher: USSR State Committee for Standards (Gosstandart) — adopted as an interstate GOST standard.
• ICS / categories: Metallurgy — Iron and steel products; forgings (ICS classification equivalent: 77.140.85 / Cast iron and steel forgings).
• Edition / version: Original 1981 adoption (implemented 1983) with Amendments No.1–4 issued in 1986, 1987, 1989 and 1990.
• Number of pages: 10 pages (typical official text length in available bibliographic records).

Scope

The standard applies to forgings (drop forgings and hot stamping) with nominal diameters (or maximum section thickness) up to 1000 mm, manufactured from a wide range of corrosion‑resistant steel and alloy grades (examples listed in the text include grades such as 20Х13, 12Х18Н9, 08Х22Н6Т, ХН65МВ, ХН78Т, ХН32Т and others). Its provisions cover forgings intended primarily for mechanical engineering and related industries where corrosion resistance and specified mechanical properties are required.

Key topics and requirements

• Classification of forgings into groups and by material grades (designation rules and example marking formats).
• Permitted sizes and dimensional tolerances for forgings up to 1000 mm (production by forging and hot stamping).
• Chemical composition limits for listed corrosion‑resistant steel and alloy grades and sampling rules for chemical analysis.
• Mechanical property requirements (minimum tensile strength, yield/limit, elongation) and hardness ranges for groups/grades.
• Impact (charpy) toughness requirements where specified, including temperature conditions for testing.
• Heat treatment regimes and requirements affecting mechanical properties and microstructure.
• Inspection and acceptance rules: sampling plans, destructive testing, hardness tests and references to nondestructive methods (ultrasonic testing where applicable).
• Marking, packaging, storage and transportation instructions for accepted forgings.
• References to relevant test methods and related GOST documents (chemical analysis, hardness, tensile and impact testing standards).

Typical use and users

Primary users are forging manufacturers, metallurgists, material engineers, quality/inspection departments, procurement specialists, designers and standards/compliance teams in industries such as machine building, chemical and petrochemical equipment manufacturing, power and energy, food processing and other sectors requiring corrosion‑resistant components. Procurement and QA personnel use the standard for specifying acceptance criteria and tests for stainless and corrosion‑resistant forgings.

Related standards

GOST 25054-81 is commonly referenced alongside other metal and forgings standards such as GOST 8479-70 (forging blanks), GOST 26131-84 (heat‑resisting steel forgings), GOST 7505-89, GOST 7829-70 and material standards for corrosion‑resistant steels (for example GOST 5632-72). It also cross-references testing and sampling standards (chemical analysis, hardness, tensile and impact tests).
