GOST 30136-95 PDF

Full title and description

GOST 30136-95 — "Carbon steel wire rods of common (ordinary) quality. Specifications" (Russian: Катанка из углеродистой стали обыкновенного качества. Технические условия). The standard defines technical requirements for wire rod (katanka) made of ordinary-quality carbon steels intended for drawing into wire and for other general purposes.

Abstract

GOST 30136-95 provides dimensions, tolerances, chemical-composition limits, mechanical-property norms, surface-quality requirements, sampling and test methods, and packing/marking rules for carbon steel wire rod of common quality. It corresponds to ISO 8457-1:1989 (steel wire rod — part 1: dimensions and tolerances) and was adopted as an interstate technical specification for CIS states.

• Number of pages: 7 pages (official print/pdf editions typically 7 pages).

Scope

The standard applies to wire rod (katanka) made from ordinary-quality carbon steels intended for subsequent drawing into wire and for other general uses. It covers permitted diameters and tolerances, allowable chemical-element limits for typical grades (e.g., St0, St1, St2, St3 series), mechanical-property norms (temporary tensile strength, reduction of area), surface quality, coil (motok) mass, sampling, testing and acceptance rules, and requirements for marking, packing, transport and storage.

Key topics and requirements

• Designation, assortment and nominal diameters of wire rod; dimensional tolerances and ovality limits (references to GOST 2590 series for round-section assortment).
• Chemical-composition limits for common steel marks (St0, St1, St2, St3 and their deoxidation levels); provisions for weldability and optional guaranteed tensile limits at customer's request.
• Mechanical properties: temporary (tensile) strength, relative narrowing (reduction of area) and rules for normalizing/testing per referenced test standards (e.g., GOST 1497 for tensile tests).
• Surface quality requirements and methodology for determining mass of scale/oxides (includes an express pickling/weight-loss method described in an informative/mandatory annex).
• Sampling, inspection and test frequency: rules for selecting coils (motki) and specimens for diameter, surface, mechanical tests, bending and microstructure checks (sampling percentages and minimum counts specified).
• Heat-treatment / cooling regimes references (single-stage and two-stage controlled cooling options) and the effect on properties; marking and conditional designations for cooling types.
• Packing, marking, transportation and storage requirements (references to GOST 7566 series for packing/transport).

Typical use and users

Manufacturers of wire rod and steel mills producing katanka; quality-control and testing laboratories in metallurgical plants; buyers and specifiers in wire drawing, construction, general engineering and fastener industries; procurement and standards engineers who need to ensure material conformity to CIS/Russian technical requirements. The standard is used when producing, accepting, testing and supplying ordinary-quality carbon wire rod.

FAQ

Q: What is this standard?

A: GOST 30136-95 is the interstate/Russian technical specification that sets requirements for carbon-steel wire rods of ordinary (commercial) quality — commonly called "katanka" — used for drawing into wire and other general purposes.

Q: What does it cover?

A: It covers assortment and nominal diameters, dimensional tolerances and ovality, chemical-composition limits for common grades, mechanical-property norms (tensile strength, reduction of area), surface-quality rules (including a method to determine mass of scale), sampling and testing regimes, conditioning/ cooling types, marking, packing, transport and storage.

Q: Who typically uses it?

A: Steel producers, wire-rod manufacturers, quality and test laboratories, purchasing/specification engineers in wire-drawing and general engineering sectors, and regulatory/standards professionals in CIS/Russian markets.

Q: Is it current or superseded?

A: Public standards registries and contemporary listings indicate GOST 30136-95 remains in force (active) and has not been formally superseded in the national/interstate registries visible in public databases. Users should verify current status in official national registries or the federal standards portal for the latest legal/registry updates before critical procurement. (Status verified in current public listings at time of this summary).

Q: Is it part of a series?

A: It is part of the metallurgical/rolled-steel series of GOSTs covering steel grades, testing methods and product assortments; it references and works together with related GOSTs (e.g., GOST 2590, GOST 380, GOST 1497, GOST 7566). It also corresponds to ISO 8457-1:1989 for dimensions and tolerances.

Q: What are the key keywords?

A: Katanka, wire rod, carbon steel, ordinary quality, dimensions, tolerances, tensile strength, mass of scale, coils, GOST 30136-95, ISO 8457-1.
