GOST 11850-72 PDF

Full title and description

GOST 11850-72 — "Steel wire for spring washers. Specifications." National (Soviet) technical standard that sets technical requirements, dimensions, mechanical properties and acceptance rules for steel wire intended for manufacture of spring (locking) washers.

Abstract

This standard specifies types, basic sizes, steel grades, mechanical properties and manufacturing/inspection requirements for steel wire of square, rectangular and trapezoidal cross-sections used to produce spring washers. It includes allowed tolerances, permissible defects and references to related normative documents and amendments.

General information

• Status: Historically introduced as a Soviet (GOST) standard; listed in multiple standards databases and commercial catalogues. It replaced GOST 11850-66 (see notes). Users should verify current legal/registry status in the national standards body before normative use.
• Publication date: Approved 1972, introduced 1 January 1973 (designation ends with -72).
• Publisher: Approved and promulgated by the State Committee for Standards of the USSR (Gosstandart); developed with participation of the Ministry of Ferrous Metallurgy.
• ICS / categories: Wire and wire products / spring elements (industry coding and group references given in the standard; e.g., industry index group references listed in source data).
• Edition / version: Original 1972/1973 edition with multiple amendments recorded (amendments in 1983, 1984, 1987, 1990 noted in commercial catalogues).
• Number of pages: Approximately 8 pages (compact technical specification sheet).

Scope

Applies to steel wire intended specifically for manufacture of spring (locking) washers. Covers wire of square, rectangular and trapezoidal sections in a range of cross‑section sizes and production states (annealed, cold‑drawn) and specifies mechanical properties and permissible deviations relevant to forming and heat treatment of washers. The standard references related GOSTs for steel grades and testing methods.

Key topics and requirements

• Permitted cross‑section shapes: square, rectangular and trapezoidal (section dimensions and tolerances defined).
• Specified steel grades for wire: typically 65G and 70 (with allowance by agreement for other steels meeting required properties and referenced GOSTs such as GOST 14959 and GOST 6402).
• Mechanical property limits (tensile/rupture strength) given by processing state (annealed, cold‑drawn) and by wire size/class.
• Surface and defect acceptance criteria (no scales, burrs, corrosion beyond allowable traces; end and shear finishing requirements).
• Production, sampling and inspection rules including references to normative testing standards and permissible coverings/finishes for washers made from the wire.
• Typical diameter/size range examples for supplied wire (commercial listings and suppliers commonly offer diameters from about 0.6 mm up to ~5 mm for spring‑washer wire).

Typical use and users

Primary users: manufacturers of spring/locking washers, fastener and hardware producers, spring workshops, metal‑processing plants and quality/inspection laboratories that produce or test wire used to form spring washers. Also used by procurement and engineering departments specifying raw wire for washer production.

Related standards

References and cross‑links in the standard include earlier version GOST 11850-66 (which it replaced), steel grade and testing standards such as GOST 14959 and GOST 6402, and other GOSTs governing coverings, hardness testing and inspection methods. Implementing documents and later normative references appear in the standard's reference list.

FAQ

Q: What is this standard?

A: A GOST (Soviet/Russian) technical specification that defines requirements for steel wire produced for the manufacture of spring (locking) washers.

Q: What does it cover?

A: Types and sizes of wire cross‑sections (square/rectangular/trapezoidal), steel grades, mechanical property limits for different processing states, surface and defect acceptance rules, and references to testing and related normative documents.

Q: Who typically uses it?

A: Manufacturers of spring washers and related fastener producers, metallurgical suppliers, product designers specifying washer raw material, and quality/inspection laboratories.

Q: Is it current or superseded?

A: The standard was approved in 1972 and introduced 1 January 1973; it replaced an earlier 1966 edition. Databases and standards vendors still list the document and recorded amendments, but national legal/registry status may vary — users should check the current national standards registry or the issuing body for up‑to‑date confirmation before relying on it as mandatory.

Q: Is it part of a series?

A: It belongs to the family of GOST standards covering wire and spring materials and references other GOSTs for steel grades, testing and coatings; not a numbered "series" per se but conceptually grouped with other wire and spring material standards.

Q: What are the key keywords?

A: Steel wire, spring washers, spring‑washer wire, square-section wire, GOST, 65G, 70, technical specification.
