6 Производственные условия
6.1 Общие положения
Если не заявлено иначе, то способ производства выбирается на усмотрение изготовителя.
6.2 Состояния после обработки
Проволока должна быть задана в одном из следующих состояний в зависимости от структуры:
— Состояние +A: Проволока является отожженной после конечной термической обработки. Заметим,
что этот материал может быть слегка деформирован за счет выпрямления, нагартовки, контроля
размера или чистовой отделки. В результате этого происходит небольшое увеличение предела
прочности на разрыв.
— Состояние +AT: Проволока является гомогенизированной после конечной термически обработки
на твердый раствор. Заметим, что этот материал может быть слегка деформирован за счет
выпрямления, нагартовки, контроля размера или чистовой отделки. В результате этого происходит
небольшое увеличение предела прочности на разрыв.
— Состояние +C: Проволока является холоднотянутой в результате последней операции для
достижения большей прочности.

ISO 16143-3:2014(R)
6.3 Отделка поверхности
Если не задано иначе, то отделка поверхности проволоки может быть одной из следующих в
зависимости от предыдущих шагов технологической обработки.
6.3.1 После холодного волочения
Это есть естественная чистота поверхности в результате волочения до конечного размера. Обычно на
поверхности проволоки оставляется смазка холодного волочения. Чистота поверхности может быть
более тусклой при сухом волочении или более светлой при мокром волочении проволоки. Тонкие
размеры обычно достигаются при мокром волочении, а более грубые – при сухом волочении.
Специальные отделки до блеска, удаление смазки и т.д., которые требуются для специального
конечного использования, должны быть согласованы на переговорах с изготовителем.
6.3.2 Отожженная
Проволока имеет тускло-матовый вид, непременно ассоциированный со спокойным мягким состоянием
отожженной проволоки, когда окончательное волочение не разрешается. При дополнительной
обработке поверхности может быть реализован ее светлый вид.
6.3.3 Полированная отделка
Проволока имеет гладкую и равномерно блестящую отделку обработанного в холодном состоянии
материала (+C), которая была достигнута за счет механического сглаживания, полировки, притирки
или шлифования.
7 Требования
7.1 Производственный процесс
Процесс выплавки стали для продукции согласно настоящей части ISO 16143 должен быть в
соответствии с ISO 4955 и ISO 16143-2. Технологическая обработка проволоки в случае, когда она не
задается в настоящей части ISO 16143 или не согласована между заинтересованными сторонами,
осуществляется на усмотрение волочильщика проволоки.
7.2 Состояние поставки
Металлопродукция должна быть поставлена согласно описанию в Разделе 6 и согласована в заказа.
7.3 Химический состав
7.3.1 Анализ плавки
Требования к химическому составу в Таблице 1 применяются в отношении химического состава при
анализе жидкой стали.
7.3.2 Результаты анализа продукции могут отличаться от предельных значений анализа жидкой
стали, данного в Таблице 1, на величины, перечисленные в Таблице 2.
7.4 Механические свойства
7.4.1 Механические свойства для отожженной проволоки
Предел прочности на разрыв и удлинение должны удовлетворять требования в Таблице 3. Она задает
механические свойства при комнатной температуре в отожженном состоянии. Для аустенитных,
4 © ISO 2014 – Все права сохраняются
---------------------- Page: 8 ----------------------
ISO 16143-3:2014(R)
аустенитно-ферритных и дисперсионно-твердеющих сталей проволока выпускается в состоянии +AT;
для ферритных и мартенситных сталей – в состоянии +A.
7.4.2 Механические свойства твердотянутой проволоки
Эта проволока выпускается в состоянии +C. Предел прочности на разрыв зависит от степени
механического упрочнения, специфического типа стали и технологической обработки материала.
Предел прочности на разрыв задается минимальным и максимальным значениями. Не все уровни
прочности при растяжении, перечисленные в Таблице 4, могут быть достигнуты для всех марок стали.
Поэтому необходимый уровень прочности при растяжении должен быть согласован между
изготовителем и заказчиком во время оформления заказа.
Таблица 4 дает обзор стандартизованных уровней прочности при растяжении и соответствующие
минимум и максимум.
7.5 Допуски на размер
Проволока круглого сечения. Заказчик должен задать нормальный допуск (N) или ограниченный допуск
(R), как определено в Таблице 5. Для некруглой проволоки допуски должны быть согласованы во
время оформления заказа.
Овальность (отклонение от формы окружности) есть разность между наибольшим и наименьшим
диаметром в одном и том же поперечном сечении проволоки. Это поперечное сечение должно быть
перпендикулярно продольной оси проволоки. Овальность не должна превышать половины общего
допуска на диаметр, который задается для бунтов.
8 Контроль, проведение испытаний и соответствие продукции установленным
требованиям
8.1 Общие положения
Изготовитель должен осуществлять подходящее управление технологическим процессом, инспекцию и
проводить испытания для гарантии, что поставка соответствует требованиям заказа.
Упомянутое выше включает следующее:
— подходящую периодичность проверки размеров продукции;
— адекватную интенсивность визуального осмотра качества поверхности продукции;
— подходящую частоту и тип испытания, чтобы удостовериться в поставке стали правильной марки.
Характер и частота этих проверок, осмотров и испытаний устанавливается изготовителем на основе
степени последовательности, которая была подтверждена заводской системой контроля качества.
Ввиду сказанного выше, отпадает необходимость в проверках для этих требований с помощью
специальных испытаний, если не

6 Manufacturing conditions
6.1 General
If not stated otherwise, the manufacturing procedure is at the discretion of the manufacturer.
6.2 Treatment conditions
The wire shall be specified in one of the following conditions, depending on the structure:
— Condition +A: The wire is annealed as the final heat treatment. Note that this material might be
slightly deformed by straightening, cold work, size control, or finish. This will result in a slight
increase of the tensile strength.
— Condition +AT: The wire is solution annealed as the final heat treatment. Note that this material
might be slightly deformed by straightening, cold work, size control, or finish. This will result in a
slight increase of the tensile strength.
— Condition +C: The wire is hard drawn as the last operation, in order to achieve higher strength.
6.3 Surface finish
If not specified otherwise, the surface finish of the wire is one of the following, depending on previous
processing steps.
6.3.1 Cold drawn
This is the natural finish resulting from the drawing to final size, generally with cold-drawing lubricant
left on. The finish will be duller for dry-drawn wire or shinier for wire that is wet drawn. Fine sizes are
commonly wet drawn, whereas coarser sizes are commonly dry drawn. Special bright finishes, lubricant
removal, etc. required for special end-use shall be negotiated with the manufacturer.

ISO 16143-3:2014(E)
6.3.2 Annealed
This is a dull matt appearance, necessarily associated with the dead soft condition of annealed wire
when no final drawing is permitted. With an additional surface treatment, a bright appearance can be
realized.
6.3.3 Polished finish
This is a smooth and uniform bright finish of cold-processed (+C) material obtained by mechanical
smoothing, burnishing, abrading, or grinding.

ISO/DIS 16143-3
Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
This second edition cancels and replaces the first edition (ISO 16143-3:2005) which has been technically
revised.
ISO 16143 consists of the following parts, under the general title Stainless steels for general purposes:
Part 1: Corrosion resistant flat products
Part 2: Corrosion resistant semi-finished products, bars and sections
Part 3: Wire
